Hidden pitches
When pitching you are normally only able to choose from a "fastball" and a "split". Hold [Left], then rotate the D-Pad clockwise and press [B] to unlock the rest of the pitches.
Choose your hit
When batting, there are five ways to hit the baseball.
Grounder: Press [Down] + [B].
Homerun (sometimes): Press [Up] + [B].
Left Field: Press [Left] + [B].
Right Field: Press [Right] + [B].
Random Hit: Press [B].
Powerful offense
Because this game uses the 2001 rosters with 2000 stats, if you play as the St. Louis Cardinals you will get both Albert Pujols and a healthy Mark McGwire. In 2000, Mark Gwire hit .305 with 32 home runs and 73 RBIs in only 89 games -- he was injured for most of the second half of the season. Projected to a full season of 162, he would have hit 58 home runs and gotten 133 RBIs. Pujols was a rookie in 2001, so he had no 2000 stats. Playing as the Cardinals, you also get CF Jim Edmonds who hit .295 with 42 home runs and 108 RBIs in 2000.
Glitch: Double play after a walk
Sometimes when a batter walks, he will stay at home plate and not go to first base. You (or the CPU) can make a double play if the next batter pops out.
