Complete a round of golf at Whistling Straits in any game mode
How to unlock Site of PGA Championship
You must complete 18 holes at each individual course listed in the trophy descriptions (Celtic Manor, Liberty National, The Greenbrier, TPC Scottsdale, and Whistling Straights) in any game mode, but you MUST complete 18 holes. If you play match play and defeat your opponent after 13 holes, it does not count so I would stick with Stroke Play.
I strongly recommend playing a 18-hole Showdown in a GamerNet Challenge to help you on your way to "GamerNet Pack Rat". Just find a challenge that you think you can beat that is played at the trophy course you are looking to unlock and give it a go. Even if you beat or fail the challenge on the 16th hole, you still have the option of finishing the round out, letting you unlock this trophy. You may not earn the GamerNet points you hoped for, but at least you'll get the Silver trophy for finishing the course.
