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.
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.
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.
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.
When the opposing team scores, walk your player to home plate. The scoring player will be dancing.
Faster base running
Quickly tap Z to run to the next base or quickly tap R to return back to a base faster.
