Using two controllers, play 1 inning games against yourself. For the away team, set throwing to analog and set it to legend. Increase the fielding and throwing error sliders. Get a guy on second base and bunt the ball. There is a great chance you will throw the ball away.
If you only have one controller, It can be done differently. You will need to increase Throwing Error and Fielding Error sliders to max. Edit an opposing team's infield to have horrible fielding stats. Play as the home team. There's a chance of the fielder throwing the ball away on a bunt attempt. I used the Dodgers edited team needed for Beat LA and they threw the ball away regularly in an Exhibition game. You can't skip or fast forward.
