Control Homerun Replay - After you have hit a homerun a replay of it will be displayed. When your batter is heading home from third base press various buttons which will enable you to see the scene from different angles.
Taunt Opponents - Hit a homerun and on the way to third (after replay) then press L1 or R1. Your player will then taunt the other team's players.
Better Pitching - Good pitchers like the Chicago Sox Mark Burhele have special pitches called a slurve. Use the Dominate Curve with Pedro.
