Easy Points
You can gain "points" for certain feats performed during a game. An easy way to get a lot of points is to throw a perfect game. This is worth 100 points. Switch controls every time the CPU is up at bat and intentionally strike out. This will get you points for 27 strikeouts, and for a perfect game. Repeat as many times as needed.

Control Homerun Replay
After hitting a homerun, a replay of it will be displayed. When you see your batter heading home from third base, press various buttons to see different angles.

Better Hitting
Immediately after the pitcher releases the ball, press Start. You will see where the ball is going and if it will be a strike or ball. Resume the game and move your batting cursor over it to get a nice powerful swing. This will help you improve your hitting. Note: You do not need to press Start directly after he lets go of the ball -- it just gives you more time to move your cursor after the game is resumed.

Use the pause technique before batting. When you see where the ball is going, try your best to get the ball as close to the point of the contact triangle (the part closest to the batter, not the thick part of the triangle). you will usually get homeruns or at least doubles.

Wait until the pitcher's arm is in motion and is coming forward, then swing. If it looks like a bad pitch do not swing. This strategy woks most of the time, and works well with players such as Giambi, Bonds, or A-Rod.

Better Pitching
The best pitchers have a pitch called a "Slurve" (for example, Mark Burhele of the Chicago White Sox). Also try the "Dominate Curve" with Pedro.

Restore Pitcher's Energy
In season, franchise or expansion mod, go to the DL, and put any pitcher on the15 day DL. Then immediately take him back into your lineup. He will have recovered all his energy.

Better Franchise Or Expansion Mode Teams
Use trades to get rid of your older less talented players for slightly better players. Even if the CPU rejects your trade, keep trying repeatedly and it is usually eventually accepted. However, make the trade reasonable, such as B- for a B or B+. If the player you really want just does not seem to want to join your team, try trading for another player who is slightly better, then return to that player you want and try again. Do this every season to keep good young players.
