All Working High Heat Major League Baseball 2003 Cheats - Playstation 2

Cheat mode
Pause game play and press [Square]x2, [Circle]x2, [L1], [R1]. A sound will confirm this portion of the code. Then, press [L1] + [L2] + [R1] + [R2]. The "Ball Cannon" (set pitch physics) and "Game State" (edit game parameters) options will now be unlocked.

Bean the batter
Select a pitch, then hold [R1] and press [X] when choosing between a ball or a strike. Note: Doing this repeatedly will result in your pitcher getting ejected from the game.

Eject other team's best players
Use two controllers and hit the CPU player. Have him charge the mound. When he is ejected, the CPU will not have as many good players.

Restore pitcher's stamina
When you are at the game menu screen just before starting a new game, return to the main menu. Then, go to the game menu screen again. One of your pitcher's stamina will be restored. Do this repeatedly to replenish your entire pitching staff's stamina.
