Extra hit:
Do the "Reset the count" trick multiple times and your batter will have an extra hit. For example, with a man on first that steals, use the trick. The hitter will now have an extra hit.

Easy homerun:
When you are up to bat with a decent power hitter, move the top of the batting cursor to where the ball is being pitched. You will hit a homerun about 90% of the time.

Hint: Easy hit:
Press R trigger before the pitcher makes his selection. When the pitch is thrown, your cursor will become small. If you hit the ball it will either be a home run, or a very hard hit.

Hint: Easy strike out:
When pitching, paint the corners and the batters will not swing, making a easy strike out. It does not matter if it is their hot or cold zone, but you should still pitch it in their cold zone.

If you have two strikes already, pitch a fastball as the first pitch followed by any other pitch. On then the last pitch, throw a curveball low and away.

Hint: Pick runners off the bases:
After a CPU runner reaches a base, very quickly press A to select the pitch type, then press B and the Analog-stick in the direction of the base to try a pickoff play. The pitcher will throw it to the base. After the throw gets to the base, run towards the base to get the runner called out. For example, if there is a CPU runner on first base, immediately after the pitcher-hitter screen appears, throw over to first base. Then, after the first basemen catches it, run to the right of first base or run in circles around the baserunner. It may not work at first, but keep repeating it.

Hint: Large batting target:
Hold R while hitting, before the pitcher starts his windup. The batting target will appear later than usual, and will be larger. The target will return to normal as the ball crosses the plate.

Hint: Change computer pitched shutouts:
Go to your schedule screen. Press X to get the list of games and start times. When you simulate computer played games, and one of the teams pitches a shutout, you can simulate it again, until both teams score. You can also play games over when you or your opponent are shut out.
