At the controller selection screen, press L to activate cheats that have been bought.

Restore pitcher's energy
In season, franchise or expansion mode, go to the DL, and put any pitcher on the 15 day DL. Then immediately take him back into your lineup. He will have recovered all of his energy.
To get more points in franchise mode to sign your free agents, during the off season either create a player and pick him up as a free agent or sign free agents and release them at the end of the season.
You can gain points for certain feats performed during a game. You can use these points to buy cards which unlock cheats, stadiums, jerseys, producers, and players. 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 this as many times as needed to get an unlimited amount of points.
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. Note: You do not need to press Start directly after the pitcher 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.
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.
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 camera angles.

Extra Free Agency Players
If you win 30 or more games with one pitcher is franchise, or expansion, and still win the Cy Young Award for the respective league, go to create a player, enter Cy Young as a name, and it will automatically create Cy Young and put him in Free Agency with an A rating. If you accomplish a sub 1.25 ERA and have more than 200 K's, so the same for Young, but enetr Nolan Ryan, and it will create Ryan, put him in Free Agency with an A rating.
