Get ejected: Hit a player while pitching three or four times and you will be ejected.
Easy fly ball catches: When you are in the outfield and are not sure where the ball is going to land because of the wind, the outfielder will lock on the ball to make an easy catch. Note: This only works under the rookie difficulty setting.
Stealing home: If you have a fairly fast runner on third base, start to steal home. Go back when the throw to third base goes home. You will be safe almost always.
Building a good team: Start a franchise or season. When you get to the season, go into the "Edit" category and select your player. Choose to move the player to another team. You then can have any desired star on your team. After your first season you will lose some players due to the fact you will be over budget, but you can do this trick again. To get better ratings for other players, do the same thing by selecting a player and then editing the desired category up or down.
