Start a two player game, with only one actual player. Throw a perfect game, striking out every batter. Save the game in the bottom of the ninth inning with two strikes and two outs. Finish the game, collect your points, and save the options. Reload the game and repeat to collect the points again.

Change to the team that you are facing and make them play poorly, allowing your original team to score a lot of runs. In the last inning, switch back to your team and claim your team's cheaply made points.

Use the following trick to get extra points to buy packs of cards. Play a quick game as the Negro Stars. Chose a bad team to play against, such as the Tigers or Devil Rays. Then, press Square to display an options screen. Go to "Game Options" and change the number of innings to 1. Play the game. When you are up to bat, keep bunting. When you are pitching, get all three outs and save your points. You should have enough for about seventeen packs of cards.
