Press L + R when choosing a team in exhibition mode.
Bunt singles
This trick will only work if it is raining. It does not matter if the bases are full or empty, but do not do this with a man on third base, as the pitcher will throw home, which results in an out. Also, do not use a slow-running batter. Have the batter bunt the ball. Because it is raining, the mud will keep the ball from rolling much. The AI will have the pitcher get the ball, rather than the catcher who is much closer. By the time the pitcher gets the ball to first base, your runners will be safe.
Easier hitting
Start a game in exhibition, quick start, or season mode. Press Start, go to "Options", and make the batting 100%. Continue your game and it should be easier to hit the ball because the batting aid is larger.
Easy wins
When u want to play a game go on options and for player 2 (the comp) if your playing one put that white bar all gone. this will make them more tired and u will get better pitches to hit I once did a no-hitter with that on.
Free triples
This trick works best with a man on first. Have the batter hit a ground ball into the outfield. Let the player on first go all the way home. If it was a good hit, he will be safe. Around the time when the batter has reached halfway to, or is already on, second base, the outfielder will throw to home plate. When the batter touches second, stop his running. When the outfielder's throw gets to the shortstop (who will if done correctly, throw to home plate) , wait until he tosses it home. As soon as the ball leaves his hand toward home, get the man on second to go to third base. If done correctly, you will now have an extra run and a man on third.
Mascot Costumes
To get mascot costumes you have to beat season mode without losing. (You have to beat the game with whatever teams you want because it only gives you the mascot of the team you beat the game with.)
Miller Park Slide
If you play at Miller Park in Wisconsin when the home team hits a home run their team's mascot will slide down Bernie Brewer's slide.
New Reds Park
When you play any game at Cinergy Park, when you hit a homerun you can see where the new Great American Ballpark is going to be built at.
