Easy points
Start a two player game, with only one actual player. Throw a perfect game, striking out every batter. Save the game in the bottom of the ninth inning with two strikes and two outs. Finish the game, collect your points, and save the options. Reload the game and repeat to collect the points again.
Change to the team that you are facing and make them play poorly, allowing your original team to score a lot of runs. In the last inning, switch back to your team and claim your team's cheaply made points.
Free balls
If you are down in the count or need a quick ball, pretend to lay down a bunt. Pull back while the pitcher is in his motion. This should result in a ball being thrown. Note: This only works up to two times in an at bat.
Restore pitcher's energy
Wait until your pitcher has low energy then pause game play. If your pitcher is still on the mound, go to "Save Game and Quit", then save the game. Restart the system, and when you go to the main menu, load the game. When you finish loading, it should automatically take you back to the game, and it should show your pitcher on the mound with the full green energy bar.
Pick off from the catcher
When the ball is released, hold [L] and the base that you would like to throw the ball to. The catcher will then snap up and throw the ball to the selected base. Note: This only works when you are pitching.
Change jerseys in franchise mode
Before playing in a franchise mode game, go to quick play, and on the team's options highlight "Change Uniform". Go back, exit quick play, load the franchise, and when you get to the play game screen on options, your pointer will be on the blacked out uniform part. Press [A] and you can change uniforms. Once you change lineups or pitchers, this option is no longer available; it only works for that one game.
Better players
Select the "Extras" option at the main menu, then choose "Player Management". On that screen is a category called "Player Editor". It allows you to improve players. In season mode, go to "GM", then choose "Player Management", then "Player Editor". Note: Making a player all A+ may result in the game freezing in later innings.
Sign All-star players to long-tern contracts for less
Create as many players as desired for the positions you want by using the "Create-A-Player" option. Collect the players you have made from the free agent pool and sign them to your team. Once you have all of your created players that you want, go to "Roster Management", then to "Long-Term Contracts". Offer each player you created a long-term contract at the same, or even for a lower price than they want. Since the players are not proven in the major leagues, they will sign for basically nothing (just for the chance to play). You can now edit their stats in "Player Editor". Make each player the best that they can be (everything A+), and you will have the best team for the lowest price. Use this in franchise or expansion modes.
Duplicate players
Start a franchise or continue an existing one. Make sure the "GM Control" option is set to all teams. Go to the GM Office, then to "Trading Block". Select any player not from your team and put them on the trading block. Then, select "Get Offers" and make sure the other player involved is also not from your team. When you select the other player, the screen will change to the regular trading screen. The person on the trading block will be in your team's section. Go to "Submit Trade". When the message stating that the trade was accepted appears, you should have the player that was not on the block. The player on the block should be on his current team and the other team involved in the trade.
