Quickly tap Z to run to the next base or quickly tap R to return back to a base faster.

Slower game:
Set the batting camera option to "Zoom" to have a slower game in almost all play modes.

Reversed batter:
Pause game play and replace the batter with a different player that bats with the same hand. Resume game play briefly until the new player is seen, then pause and return to the line-up screen. Then, replace that batter with a player that bats with the opposite hand.

Dancing player:
When the opposing team scores, walk your player to home plate. The scoring player will be dancing.

Quick recovery:
After a player becomes injured, send him to the minor leagues, then immediately return him to the rotation.

Hint: Easy hits:
Hit the ball anywhere in fair territory, then quickly pause game play. Change the controller options to control the opposing team, then resume the game. Intentionally miss the ball, allowing the batter to reach base before switching back.

Hint: Keep a low ERA:
Press Start to pause game play in season mode if a home run is hit against your pitcher. This must be done before the ball leaves the park. Select the "Bullpen" and "Bullpen To Mound" options to change your current pitcher for another player. After game play is resumed, the new pitcher will be charged with the home run, allowing the original pitcher to keep a lower ERA.

Hint: CPU bunts:
If a CPU batter misses a bunt, he will automatically make a second attempt on the next pitch. Use this to your advantage by pressing B after selecting a pitch to throw a pitch out.

Hint: Picking off a CPU baserunner:
If the CPU reaches second base by stealing, the baserunner will almost always try to steal third as well. Throw a pitch out to increase the chance for a pick-off.

Hint: Weird play:
Run along the wall and hold Z, then throw the ball to any base. The player will throw the ball into the air and catch it.

Hint: See the catcher:
Select the Cleveland Indians as a team and Enir Diaz as the catcher. He will be visible when the pitch is thrown.
