More runs:
Get Barry Bonds to bat in the third spot in the order and play against the Cubs. Take control of the Cubs and start intentionally walking everyone until Barry Bonds is up for the second time. Rotate the hitting icon so it will hit a home run. Make contact and you will hit a grand slam. Repeat this as many times as needed. Note: Do not check the box score after 100 runs or the game will freeze.
More 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.
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.
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 (except A) to see different angles.
Improved 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.
Easy cards:
Use the following trick to unlock all the cards in one or two games. Once you unlock the Cooperstown Legends and the Pixels, play as the Legends. You will find that within the fifth or sixth inning, every hit equals ten points and possibly more. Constantly hit homeruns and strike out the batters and you should have forty to fifty packs to open after the game. This is the easiest way to complete your card collection and unlock the cheats.
Designated hitters:
In season, expansion or franchise mode, create players then trade them for the person you want. The best created player you can make is a designated hitter. Use the following settings. Note: Only American League teams need designated hitters. If you want someone in the National League, then trade your created designated hitter for a good American League player then trade him for the desired National League player.
