Extra out on play: Throw the ball to a base when fielding. This trick works better at second base. Keep throwing the ball to that base until the player over-throws it into the outfield. At times the game will call another out if the ball is caught.
Baseball Bloopers FMV sequence: Enter the start menu and allow the MLB '99 demo to run. Watch it until one half of the inning is over, and then a special FMV sequence, along with the credits, will appear.
Fights: Intentionally hit a batter, then immediately press X(3). The announcer will say "That out to clear the dugout" before the fight begins. Note: A few attempts may be necessary before a fight breaks out.
Hint: Easy hits: When playing the CPU hold Down while hitting and press Power. The batter should get a hit approximately 90% of the time. This is especially useful in spring training mode.
Hint: Easy homeruns: Hold Up/Left when at bat and keep the buttons held after the ball is hit. This will make the ball fly past the left fielder, however he may catch the ball.
Hint: Easy strikeouts: Get a pitcher with a good arm and a sinker. Pitch a sinker to the batter inside and down a little bit, outside the strike-zone. If the right spot is found, keep pitching there to strike the batter out in five pitches.
Super player: Enter Scott Murray or any other development team name as a player name at the player creation screen.
