Welcome to The Show yet again for the PS3’s number one rated sports game series. The game saw its debut last year on PS4, but this year there are a number of improvements, and with a new game, comes a brand new trophy list. Actually, more than that; three to be exact, what with each version of the game containing its own separate trophy list. After the following step list, there’s a preface for new players to the series as well as how to set up the game with sliders and rosters. If you’re a veteran, you probably already know how to do this, but read on if you need a refresher. For new players, though, I recommend you read the entirety of the following before reading the trophy list itself; it will initiate you with how the game works and how rosters and sliders maximize your chances of earning trophies.

Credits:
I give many of my thanks to PlaystationTrophies.org’s very own: PS4Trophies Wozamil, who provided some of the videos which will be used throughout the portion this guide. Also, thanks to M-Easy in addition to ch2423, who have uploaded sliders and rosters, which will be mentioned for use in this guide. Finally, I'd also like to credit MrMinderBinder for corrections regarding the Legends Never Die trophy.

Step 1:

If you’re playing the PS Vita version, skip this section and go straight to Step 2.

Diamond Dynasty Distilled is an overhaul of the series’ long-standing mode Diamond Dynasty, so of course they decide to throw in a few trophies for us to earn. It’s a mode similar to Fantasy Baseball in which you collect players, stadiums and gear, represented as cards, to build a baseball team. On the main menu, select Diamond Dynasty to get started. From here, you’ll select a team name and location and be given a few packs to start. You’ll be grinding by playing against the CPU to earn stubs, the form of currency used in the game. Using those stubs, you’ll be buying Colorado Rockies players on the marketplace to get a legends player on your team ,as well as opening packs and flipping cards on the marketplace. This one is the main grind of the game, but I have put it first since it’ll get you familiarized with the game’s mechanics. During this step, you’ll earn:

Legends Never Die (Absent on PS Vita)
Hoarder (Absent on PS Vita)
Trophy Hunter’s Trophy Trophy (Absent on PS Vita)
Supply or Demand (Absent on PS Vita)
Oh, It’s Perfect! (Absent on PS Vita)

Step 2:

This is where the frustration starts. You may have earned some of these trophies playing Diamond Dynasty, but trophies like Nope and Sorry Kid will require some real effort and luck to earn. You don’t have to earn the following trophies in any particular order, but the two I just mentioned will likely be your last given how frustrating they can be. During this step, you’ll earn:

Follow The Leader ( on PS Vita)
The Creative Director
Cut. It. Out.
Don’t Test Me ( on PS Vita)
Got Doubles? ( on PS Vita)
The “Me” In Team
Straight Paint
The Claw
Sorry Kid
A One, A Two… ( on PS Vita)
#PitchersWhoRake
Bruh
Nope( on PS Vita)
Feel The Breeze
Good Eye ( on PS Vita)
Crushed It! ( on PS Vita)
Lucky
Graveyard Shift ( on PS Vita)
You’re My Boy Blue (Absent on PS Vita)
See What I Did There? (Absent on PS Vita)
A Complete Game

On the game’s difficulty:
This platinum's difficulty sits at about a 3 out of 10. One thing you should note is that this is the difficulty provided by other users on the forum, most of whom played MLB 14: The Show and versions before. As the people who have voted, including myself, are veterans to the series, you may find this game significantly more difficult to platinum if you are new.

Also, if you are new, navigate to Options on the main menu and click User Settings. Within this menu, select Gameplay Options. Within this menu, you can tune the game’s settings, but for the purposes of this guide, set every instance of any settings set to Beginner, to Rookie. Beginner is a dynamic difficulty that adjusts how the game works based on your performance. Every setting like this needs to be set to Rookie. I’ll assume you have done so for the rest of this guide. After changing all the settings, back out and click Set as Default to confirm them. Then back out again and click Apply Changes to save the settings.

That being said, while this game’s trophies are frustrating, they’re not inherently difficult. Difficulty would imply that the trophies are inherently hard in terms of skill. They just require absurd amounts of luck and patience. For the luck-based trophies like Nope and Sorry Kid, you’ll come close to earning them many, many times and may become frustrated at the fact.

On sliders and rosters:
If you’re new to the game, sliders and rosters are imperative to earning the trophies. Sliders modify game conditions, such as how fast fielders or baserunners run. Rosters modify the players themselves, changing their skill levels to make trophies easier.

For the majority of the trophies, you’ll want to download ch2423’s sliders and rosters from the vault, which can be found at the main menu. When looking at the list of rosters and sliders that the community has uploaded, ch2423’s will be near the top. Download both of them and apply them in the options menu on the main menu; select Load Data and load both the sliders and rosters. For most of the exhibition trophies I’ll assume you have both loaded and ready to go. Otherwise, I’ll mention in each specific trophy below whether to change something, or download a different roster.

On the PS Vita version:
The PS Vita version is different in a number of ways from its console counterparts. Most notably, it does not have any online content at all save for downloading the official live rosters, you’ll have to modify these settings yourself.

For the sliders, go to the options menu on the main menu and select User Settings, then My Sliders. Click Modify.

To their maximum (Yellow bar all the way to the right side):

Human Contact
Human Power
Human Timing
Human Solid Hits
Human Starter Stamina
Human Reliever Stamina
Human Pitcher Control
Human Pitcher Consistency
CPU Foul Frequency
CPU Strike Frequency

To their minimum (Grey bar all the way to the left side):

Dynamic Difficulty Sensitivity
Human Foul Frequency
CPU Contact
CPU Power
CPU Timing
CPU Pickoffs
Pitch Speed
Baserunner Speed
Baserunner Steal Ability
Baserunner Steal Frequency
Wind
Injury Frequency

After that, swipe right along the top bar to confirm the settings, then, when back in the options menu, Click Data Utility, then Save, then My Sliders to save.

For the rosters, you will have to travel to Create & Edit on the options menu. Here, select Edit Player. From here, you can pick any two teams, but for the purposes of this guide, We’ll be playing as the Red Sox against the Yankees. Use the right stick to find these teams. When you’re at the Red Sox, use and to see each player and their position. Navigate to starting pitchers and hover over Clay Buchkolz, then click Edit Player. Then, press to see his Attributes. Max them all out, then press again and do the same for his Pitching Attributes too. After you’re done, press to confirm that player’s settings. Do the same for every position player that is marked ‘MLB’ in this team.

For the Yankees, we’ll do the reverse, but not to such a harsh extent since we’ll still want them to be able to hit. Instead, we’ll dial their settings to about 33 each. Do the same for all Yankees position players. It is not necessary to do anything to their pitcher unless prompted.

After you have done everything mentioned above, back out and tap Data Utility on the right hand side of the options screen. Then, click Save, then Roster. Roster should have a tick next to it. Save it with an appropriate name. Whenever you boot up the game, you’ll have to load both the rosters and the sliders from the Data Utility menu, as they reset when you close the game.

That’s it. You’re ready for the rest of the guide. If you liked it or it helped with your platinum trophy, feel free to give me feedback as it's my first guide.

[PST Would Like to Thank BeforeJam for this Roadmap]

A Complete Game

Earn all of the MLB® 15 The Show™ Trophies.
Congrats on the shiny new platinum for your collection. Or two. Or three if you have saintlike patience (and all three consoles).
Follow The Leader

While batting, successfully perform a double steal with runners on first and second. Hit & Runs will not count. Must play an uninterrupted game against the CPU without switching sides or fast-forwarding. Excludes Community Challenges mode.
First, you’ll have to get yourself into a situation with runners on both first and second base. If you have baserunning decisions set to assist in the options menu, this is very easy as baserunners won’t run further than one base unless you tell them to. This means that any hit that is not a home run results in a single if you just do nothing. Play as you normally would until you have runners on first and second. You also CANNOT have a runner on third as he will have no option to run home, resulting in a very easy triple play for the CPU.

Finally, when you have runners on first and second and the next batter is up, hold without touching until the pitcher is doing his wind-up animation. This is when the pitcher begins the animation to his face to throw his pitch. When this happens, release to let your baserunners loose. If done correctly, early enough in the pitcher’s animation and with the necessary sliders and rosters, you’ll steal both bases with plenty of time to spare.

If you have never stolen a base before, this can take a bit to get the timing of stealing bases right. With the rosters, however, the pitcher’s wind-up animation is also about twice as long as normal, so getting the timing right is more lenient. The trophy will unlock as soon as the play is finished.
The Creative Director

Influence a base hit with the directional hitting interface. Must play an uninterrupted game against the CPU without switching sides or fast-forwarding (excluding RTTS). Excludes Community Challenges mode.
This one’s real easy. When you’re in a game, simply tilt the left analog stick while hitting the ball to influence the direction the ball will travel. This is the directional hitting interface. Get on base having hit a ball while tilting the stick to earn the trophy. You must have your Hitting Interface option in the Batting & Baserunning section in the Gameplay Options menu set to Directional for the directional hitting interface to appear.
Cut. It. Out.

Use the new mid-flight cutoff feature while on defense. Excludes Community Challenges mode.
This one’s kind of a pain to get working properly. Essentially what you have to do is get into a situation wherein you can throw the ball to another fielder, with a third fielder in the way. It’s as confusing as it sounds. Often this comes in the form of catching a flyout ball in the outfield. When an applicable situation arises, a blue line will appear in the middle of the giant baseball where you have to stand your outfielder in to catch the ball. Press one of the buttons to throw to a base BEFORE this blue line disappears to enable a cutoff.

After that, you’ll have to press ( on PS Vita) when the cutoff symbol appears to cut the ball off. Yes, it’s that unnecessarily convoluted and you’ll probably never use the feature again after this trophy. Watch the video below if it’s still really confusing, courtesy of PS4Trophies Wozamil:

The trophy will unlock as soon as the play is finished. Also, you will need Fielding Decision set to Assist and Throwing Decision set to Off in the Fielding section of the Gameplay Options menu to get the trophy working. Having either set to Auto or On will invalidate the trophy.
Don't Test Me

With any outfielder, throw out a runner at the plate. Must play an uninterrupted game against the CPU without switching sides or fast-forwarding (excluding RTTS). Excludes Community Challenges mode.
This one’s also a bit frustrating to get the conditions right. Basically an outfielder will have to catch the ball with enough time to spare to throw the ball down to the home plate. The reason it’s a pain is because the AI is generally smart enough not to try to run home when there’s a chance you’ll throw them out.

When an outfielder gets a hold of the ball, hold to throw to the catcher. Generally when you get the trophy, it will be because the center fielder was relatively close and there was a runner at third trying to run home. You can use quick shifts, as described below, to set the outfielders to Shallow and get the center fielder closer to the home plate.

Additionally, there’s a slider called "Baserunner Speed", which you may want to turn to the minimum to make the opposing team’s baserunners take a longer time to reach the home plate. This especially helps when the bases are loaded and the AI has no choice but to send the third base baserunner home. Use the sliders mentioned in the first post to maximize the chance of getting the trophy. Have a look at a video I've uploaded to get an idea of an appropriate situation for the trophy:

The trophy will unlock as soon as the play is finished. Also, you will need Fielding Decision set to Assist and Throwing Decision set to Off in the Fielding section of the Gameplay Options menu to get the trophy working. Having either set to Auto or On means the AI will never throw to home plate when they're able to throw to first.
Got Doubles?

While batting, hit back-to-back doubles. Must play an uninterrupted game against the CPU without switching sides or fast-forwarding. Excludes Community Challenges mode.
This one you’ll earn in due time using sliders and rosters. One tip is to set baserunning to Assist. This way if you hit one in the outfield that could easily make it a triple instead of a double, just hold the toward your baserunner (his location is shown in the top corner) and press to get him to run to second base. Do this twice in a row and the trophy is yours. They have to be exact doubles; a triple and a double won’t count. Also, strangely, reaching third on a double+error does not count as a double for this trophy. The trophy will unlock as soon as the second play is finished.
The "Me" In Team

In any game mode, total 7 RBIs with one player in a game. Must play an uninterrupted game against the CPU without switching sides or fast-forwarding (excluding RTTS). Excludes Community Challenges mode.
Use the sliders mentioned above and the rosters to maximize your chances of getting runners on base. Here you’ll be using anything you have learned about plate discipline, timing, power etc. to get runners home. Most of the players in the sliders have generally equal skill at hitting, so I wouldn’t say to focus on one batter. Additionally, with both the sliders and rosters, it becomes very easy to dish balls to center field where nobody can reach them. In short, you’ll get this trophy because you won the game 34 to nothing, not because you focused on one player.

Something you might also want to try is to lower the other team’s stats (for the recommended roster, the Yankees) to where their fielding stats are all at zero. You can do this in Create & Edit Player in the options function on the main menu, then scrolling using and ( and on PS Vita) to find the Yankees. This means they’ll error far more when used in conjunction with fielding errors and throwing errors set to max in the sliders.

Also, if you do want to go down the route of using one player, you can try to load the bases and get a power hitter to hit a home run. For every baserunner, that’s +1 RBI in addition to 1 for the batter himself. Each grand slam is a +4 RBIs, so you’ll only need two of these to meet the requirements of this trophy. This is relatively easy to do if you set baserunning decisions to assist as mentioned above for the Follow The Leader trophy. Doing that, baserunners won’t run more than one base unless it’s a home run. Thus, it’s very easy to hit three singles in a row. Follow that up with a home run from a power hitter.

I personally got the trophy when I was not focusing on a single player, instead just trying to get as many runs as possible. I got it in the middle of the sixth inning. The trophy will unlock as soon as the 7th RBI with one player is recorded.
Straight Paint

Complete a full game (extra innings included) without walking a batter from the opposing team. Must have the innings option set to 9 and play an uninterrupted game against the CPU without switching sides or fast-forwarding. Excludes Community Challenges and Quick Counts.
Using the above sliders and rosters, this is relatively easy as your pitcher will be super consistent and pitch nearly exactly where you tell him to. Basically you’ll want to throw offspeed pitches in the strike zone. The opposing Yankees, which have been made inferior by the sliders, will have issues hitting stuff like curveballs and sliders.

Additionally, if there’s a risk you’ll walk a batter, for example if the count is 3-0, just throw fastballs down the center. It’s unlikely he’ll hit them, given his stats anyway. One thing that is also important to remember is that you don’t have to win the game to earn the trophy, so don’t worry about losing because you should had thrown fastballs while getting a few runs scored. Also, hitting the batter himself with the ball and giving them a free first base does NOT count as a walk. The trophy will unlock once the game ends.
The Claw

While pitching, strike out 15 batters in a single game. Must play an uninterrupted game against the CPU without switching sides or fast-forwarding. Excludes Community Challenges and Quick Counts.
(3)
Utilize the rosters and sliders and the CPU won’t be able to get a hit in. Even throwing fastballs straight down the middle is difficult since your pitcher throws them near 100MPH, though I would not recommend it just in case. Offspeed pitches, such as a slider or curveball, inside the strike zone are your main tool here since the CPU, now that it has been weakened using sliders and rosters, has issues following and hitting pitches.

As a result, strikeouts come fairly easily and you’ll most likely get this naturally while playing an exhibition game with sliders and rosters. Some have reported that going into extra innings invalidates the trophy, but I can’t verify it for sure since I got it fairly early in a game. The trophy will unlock once the 15th batter strikes out.
Sorry Kid

Catch a foul ball out of the field of play. User cannot switch sides during game. Excludes Community Challenges mode.
This one is likely the last trophy you’ll earn during your platinum run. It’s a real pain since foul balls usually travel either very shallow or way out, with little in between that can be caught out of the field of play. For the sliders, instead of using the standard ones mentioned in the top post, you’ll want to download M-Easy’s sliders and rosters from the slider vault and roster vault. When searching for the rosters, press and filter Fantasy rosters only. M-Easy’s roster will be near the top. Do the same for sliders, but sort by Arcade instead. After downloading and applying both sliders, the opposite team’s hitters will hit the ball often, but will mostly be foul balls.

If you’re on the PS Vita version, use your standard sliders, but bump CPU contact up three notches. This will help your pitcher hit the ball more consistently. Also, modify your pitcher to have a 2-seam fastball in his repertoire and make it a fairly good one; all of its stats should be around 80 or above.

Next, pick the San Francisco Giants as your team and Tim Hudson as your pitcher (Or whatever team and pitcher you modified, if on PS Vita). Between the middle and bottom of the third is ideal. In essence you won’t have to move the at all since the 2-seam fastball you’re meant to use () already lands here. Fastballs here often tend to pop up high, but not travel very far. Otherwise, this trophy is largely chance. Once you do get an opportunity, move your fielder, in this case usually the catcher, to the edge where the ball will be caught. If the conditions are right, he’ll lean over slightly over the barrier to catch the ball. Other than that, I can’t help much. It’s the most luck-based trophy in the game and you will get many, many frustrating popups that land just outside of where your player can catch it. Watch the video below I recorded if you want an example of it:

The trophy will unlock as soon as the play is finished. Also, you will need Fielding Decision set to Assist and Throwing Decision set to Off in the Fielding section of the Gameplay Options menu to get the trophy working. Having either set to Auto or On can invalidate the trophy. Some have reported the trophy popping with automatic fielding, but just in case, do it manually. One important thing to note is to let go of the analog stick when you get to the edge. If you keep running into the barrier your player won’t even attempt to catch the ball. I have given up a perfect shot at earning the trophy once by doing so and it’s the most rage-inducing thing ever since you know you could have avoided it.
A One, A Two...

Get three double plays in one game. Must play an uninterrupted game against the CPU without switching sides or fast-forwarding. Excludes Community Challenges mode.
This one’s fairly easy given use of the sliders and rosters. When you’re pitching, intentionally walk two batters with +. Then, pitch fastballs down the center on the third batter. The CPU is terrible with the sliders to the point that it may actually strike out here, but generally they’ll hit a short ground ball where your infielders can get it. Then turn the double play by throwing to second with , then to first with . Repeat all of the above steps twice more in the one game to earn the trophy.

Luckily you can have Fielding Decisions and Throwing Decisions set to Auto and On for this trophy, which is how I did it. This way your boosted fielders will always make the right decisions that are best for maximizing outs and will always turn a double play when you meet the above conditions. Also, set Baserunner Speed to its lowest setting in the sliders so the baserunners become ridiculously slow at running, giving you ample opportunity to turn the double play. The trophy will unlock as soon as the play is finished.
#PitchersWhoRake

Hit a home run with a pitcher. Must play an uninterrupted game against the CPU without switching sides or fast-forwarding. Excludes Community Challenges and Home Run Derby™ modes.
Sliders and rosters, as always. But first, navigate to the Create & Edit Player function in the Options section of the main menu. Here you can make a player with maxed hitting stats as, even in the rosters, the Red Sox’s boosted pitcher has unchanged hitting stats and there is currently no roster ideal for this trophy in the roster vault. On Vita, you will probably already have done this having read the earlier part of the guide. If not, refer to On the PS Vita version above.

Select Edit Player from this menu, then press to navigate to Starting Pitchers. Then, press once to navigate to the Red Sox’s players. Select Clay Buchkolz, then Edit Player, then to modify his hitting attributes. Max them all out, then press / to save that pitcher’s new settings.

Then, navigate to Options in the main menu, then select Data Utility on the left hand side. Then, select Save Data from this menu. Roster in this menu should have a tick next to it, in that case save the roster with an appropriate name.

Now, instead of playing against the Yankees, however, play against a poorly-ranked National League team such as the Milwaukee Brewers, with them being the Home team. If you’re new to the sport, this is because, when NL teams are the home team, pitchers are included in the batting lineup. Select Clay Buchkolz when you are selecting your pitcher.

Now, when it’s your pitcher’s turn to bat, his boosted stats should help you hit the home run. As always with HRs though, it’s still about the right timing and pitch, so it may take you a few tries. If you’re still having issues, place the pitcher at the start of the batting lineup while setting up the game. This means he’ll bat first and you can simply restart the game and try again if he gets an out or a base hit instead of a home run.

The trophy will unlock as soon as the play is finished. Also, only a home run by hitting the ball outside the outfield fence will count. Inside the park home runs will invalidate the trophy.
Nope

Successfully rob a home run. User cannot switch sides during game. Excludes Community Challenges mode.
This one is highly variable for people. I got the trophy in my first day of owning the game on PS4, but am still struggling to get it on Vita. The best approach I have found is to load up your rosters, but set the following sliders to their maximum:

CPU Contact
CPU Power
CPU Timing
CPU Solid Hits

Now, instead of playing as the Red Sox against the Yankees, do it the opposite way around. Pitch fastballs straight down the middle until a batter slams one. Now, depending on the distance past the outfield fence it landed, press /, select Sliders and take down the CPU Power slider down a couple notches. Rinse and repeat till you have a hit that gives you orange circles indicating that a home run can be robbed.

You’ll have to react fast when this happens since it may be your only chance for a while. Using your outfielder, run up to the fence. As you’re approaching it, you’ll have to hold to jump at the wall. Too far away from the wall and you’ll just dive straight into the ground. Too close and your fielder will hit the wall like a brick.

Thus, you’ll have to time it right. Have a look at the video below by PS4Trophies Wozamil to get a feel for it before attempting the trophy:

The trophy will unlock as soon as the play is finished. Also, you will need Fielding Decision set to Assist and Throwing Decision set to Off in the Fielding section of the Gameplay Options menu to get the trophy working. Having either set to Auto or On will cause the outfielder not to time his jump correctly and you’ll never earn the trophy that way.
Feel The Breeze

In a single inning, strike out 3 batters in a row with the same pitcher. Must play an uninterrupted game against the CPU without switching sides or fast-forwarding (excluding RTTS). Excludes Community Challenges and Quick Counts.
This will probably be one of the first trophies that you will earn using the sliders and rosters. Playing as the Red Sox against the Yankees, pitch using offspeeds to fool the batters, who are now worse thanks to the sliders and rosters.

You need to strike three out in succession, so if another batter gets a base hit in between, that invalidates the trophy. Also, if you record a dropped third strike, the trophy will not unlock even if you throw the batter out at first.
Good Eye

Perform a check swing on a ball just outside the strike zone. Must play an uninterrupted game against the CPU without switching sides or fast-forwarding (excluding RTTS). Excludes Community Challenges mode.
You’ll probably get this one inadvertently if you learn how to check your swing. Essentially, tap , but don’t hold it. If the button was pressed for a short enough time, your batter will stop his swing halfway. This is a check swing.

When a pitcher throws a pitch that looks a little bit outside the strike zone, but not that far out, try this. If you have got terrible eyesight for strikes and balls. Try it on every pitch until you get it. Odds are you’ll unlock it before one at-bat is over. The trophy will unlock as soon as you successfully check your swing.
Lucky

With any batter on offense, reach base on an error. Must play an uninterrupted game against the CPU without switching sides or fast-forwarding (excluding RTTS). Excludes Community Challenges mode.
If you use the same sliders and rosters you created for The “Me” In Team, you will most likely have already earned this trophy while pursuing that one. If not, refer to that trophy’s instructions as to how you can maximize your chances of reaching base on an error. Then, play normally. You’ll eventually get to an at-bat where you messed up and hit a grounder in the infield (Where you might also get the Crushed It! trophy). A fielder on the opposing team will throw to first and the error is usually the ball sailing over the first baseman’s head or them dropping the ball when catching it. Have a look at the video I uploaded below if you want an example:

Also, if you reach second or third base on a single+error, for example when you reached first, but the CPU erred and you continued to second, the trophy won’t unlock. This is because that play was a hit rather than purely an error. The trophy will unlock as soon as the play is finished.
Graveyard Shift

Use the new quick shift feature, while on defense, to successfully record an out. Must play an uninterrupted game against the CPU without switching sides or fast-forwarding. Excludes Community Challenges mode.
While pitching, press to access quick shifts. Here, you can quickly move your fielders to different positions to gain a strategic advantage. Shift both the outfielders and infielders to whatever you feel is appropriate for the situation. Then, pitch until the opposing batter hits a grounder in the infield or a flyout anywhere.

Also bear in mind that if you only shift the infielders and an outfielder records the out, or vice-versa, the trophy won’t unlock. This is why I recommended to shift both. Also, if the pitcher records the out by catching the ball in the air or throwing the batter out at first, the trophy also won’t unlock as the pitcher can’t be shifted. As you can probably tell at this point, strikeouts and throws out from dropped third strikes don’t count either. Lastly, shifts reset after every at-bat, so if the batter strikes out, gets thrown out by the pitcher or catcher, or records a hit, repeat all of the above steps as the fielders will have reverted to their original positions.
Legends Never Die

In Diamond Dynasty, play in a game with or against a Legend player. Must complete a full 9 inning game.
Simply play a game with a Legends player in it. You might get lucky and play against someone who has a Legends player on their team. I didn't, however. I did it the long way. This method also requires stubs; refer to Oh, It's Perfect! below for tips on earning them.

To get a Legends player, you'll have to obtain the majority of players card for one team. These range from 35-40 per team. For my trophy, I went for the Milwaukee Brewers as they have the least amount of cards at 35. Others have also suggested the Colorado Rockies and the Arizona Diamondbacks as being cheaper overall than the Brewers. I'd suggest to pursue those instead.

To buy cards of a specific team, enter the Marketplace, then Community Market on the left side of the Diamond Dynasty menu. You should already be looking at the MLB Cards section, but if not, press or until you are. From here, press to bring up the filters menu. Scroll down to the bottom to select the team to filter by, choosing the team you've chosen to pursue. Then press / to search. You'll be presented with three pages of entirely players of that team to buy. You'll need around 15 000 stubs to buy the cheapest Brewers players necessary, but reportedly less for cheaper teams such as the Rockies or Diamondbacks; the Rockies in particular can be completed for around 3 000 stubs buying only the cheapest players. Keep in mind prices vary a little bit as other players set them themselves. Also, make sure to scroll through with and instead of and as doing the latter changes the category and clears your filtered search.

After buying the necessary amount different players, go back to the Diamond Dynasty screen and select Card Collection, in the bottom right corner of the screen. Use and to scroll between teams until you're at the your team. Your screen should look something like this:

If your progress is at "35 OF 35", or however many amount your team is, you can press / to claim the Legends player, in my case Robin Yount, to add to your team. Unfortunately, this will forfeit the ability to resell the players in your card collection, so you won't be able to make the stubs you invested back.

Now go back to My Squad, in the center of the Diamond Dynasty screen, and use and to find the position your new Legends player plays. For me, Robin Yount is a shortstop. Press on him to bring up your lineup and again on your old player of that position to replace him with your legends. Alternatively, if the legends player is your highest rated player of that position, you can also press to generate a new lineup with him in it.

Finally, click Play Ball on the top right side of the Diamond Dynasty screen, then select either Head to Head or Play VS CPU to play a game. I recommend the latter as the former requires another player. You must play a full 9 inning game to get the trophy. Additionally, you cannot substitute the Legends player at any point.
You're My Boy Blue

Successfully win a replay challenge.
Another luck based trophy, but this one will come naturally in your time with the game. When you get thrown out, at a base, you may get an opportunity to challenge. This will generally only happen if you beat out the throw, but the game, to simulate flawed umpire calls like in real life, calls it out.

So when that happens, press to review the play. After that, if you beat out the throw, the umpires will overturn the call and you will be awarded first base. The trophy will unlock as soon as the call is overturned.

Perform a slide step and successfully throw out a baserunner. Must play an uninterrupted game against the CPU without switching sides or fast-forwarding. Excludes Community Challenges mode.
This trophy's broken/glitched, but in a good way: slide steps are meant for runners already on base, but you can do it to the batter instead. To put it simply, while using the Classic pitching setting hold, after you select your pitch, then press to throw. If the opposing batter hits it in the infield, the trophy is yours. Luckily you can have Fielding Decisions and Throwing Decisions set to Auto and On for this trophy, which is how I did it. The trophy will unlock as soon as the play is finished.

Trophy Hunter's Trophy Trophy

Purchase or be rewarded with the Ritual item "Trophy Hunter's Trophy."

You’ll get this on the way to the Hoarder trophy. The Trophy Hunter’s Trophy is a ritual item that went for high prices at launch but has since become very cheap, most going for exactly 1 stub, because of being oversaturated in the marketplace. From the main menu, press to view the Locker, then select Inventory. Here, you can view items you have or haven’t gotten. Press until you’re looking at ritual items. In that list, you can find the Trophy Hunter’s Trophy. Pressing on it will give you the opportunity to View in Marketplace. Click that, and from there, press Buy/Sell Options. Now click Buy, then Buy Now to purchase the trophy if one is there. Once you do and the trophy unlocks, click Sell right next to Buy to put the one you just bought onto the marketplace so others can earn the trophy.
Supply or Demand

Using the buy now or sell now mechanic, purchase or sell any item on the marketplace.
You will earn this trophy while pursuing Legends Never Die, Trophy Hunter's Trophy Trophy and Oh, It's Perfect!. The trophy will unlock as soon as you have purchased your first item on the community market.
Oh, It's Perfect!

Be rewarded with a diamond quality item (purchasing will not unlock the trophy).
This one is just opening packs until you get a diamond. I can’t speak for anyone else, but I got this trophy by spending a whole lot of stubs, over 50 grand, on the most expensive pack on the marketplace, which has over 100 times the chance of giving you a diamond compared to the basic pack. That pack gave me two diamond cards. Honestly though, that involves a ton of grinding Diamond Dynasty games for stubs, which is a pain especially since the developers removed the ability to earn stubs via Community Challenges.

See this thread by Wozamil for stub grinding tips.

The trophy will unlock as soon as you open the pack containing a diamond quality card. Spending an absurd amount of stubs buying a diamond player through the community market doesn't work; you must get the card by pure luck in a pack.

Bruh

While pitching, give up a home run to the first batter of the game (inside-the-park HRs excluded). Must play an uninterrupted game against the CPU without switching sides or fast-forwarding. Excludes Community Challenges, Practice, and Challenge Of The Week.
Another simple one. Load up your rosters, but set the following sliders to their maximum:

CPU Contact
CPU Power
CPU Timing
CPU Solid Hits

Now, instead of playing as the Red Sox against the Yankees, do it the opposite way around. Now you’re a bad team playing against a good one. Pitch fastballs straight down the middle until the first batter on the CPU team hits a home run. If he strikes out or gets thrown out, restart the game. The trophy will unlock as soon as the play is finished. Inside the park home runs do not count, so fielding deliberately poorly will not work.
Crushed It!

With a full swing, hit a fair ball that travels less than 13 feet. Must play an uninterrupted game against the CPU without switching sides or fast-forwarding (excluding RTTS). Excludes Community Challenges, Practice, and Challenge Of The Week.
This will most likely be one of the first trophies you earn during your platinum run. Usually it’s the result of chasing a ball pitched low in the strike zone or below it. What essentially happens is you slam the ball straight into the dirt in front of you, causing both the catcher and pitcher to run after it. There’s not much else to it.

Note that you do not have to reach base to earn the trophy, so if the catcher throws you out running to first base, the trophy should still unlock regardless. The trophy will unlock as soon as the play starts. Bunting will not work as it has to be a full swing. Also, vertical distance counts against this trophy, so hitting a high fly ball that does not travel very far in the infield do not count either.
