Good hits
If you guess a four seam fastball every time you will increase your chances of hitting the ball, and hit the ball further.

Easy home runs:
Start season mode. Press Start during a game and go to the options. Go to "User Game Tuning" then increase your contact and power until it is a full bar. You will now be able to hit a home run with almost every at bat.

Quick win:
Score a run then press Start. Go to "Fast Forward" and select "End Of Game". You will win.

Inside the park home run:
When you are at bat, if the ball goes to the entrance of a dug out, the opposing team will try to pick it up but will not be able to get to it. Keep running until you get to home plate.

Big ball:
Pause game play, then press Up, Right, Down, Left, Right, Down, Left, Up.
