Put Legends on Any Team  -  First, buy two Classic Teams (i.e. '27 Yankees, '55 Dodgers, '46 Red Sox...ect) from the Skybox after obtaining enough challenge points.

Then go to "Team Rosters" (from "Manage Roster" menu inside "Options") and scroll to one of your Classic Teams. Highlight any player and choose to trade that player.

From the Trade Players screen, press L2 four times and Legends teams will be accessible to trade with. Complete a trade with your Classic Team. Now you can just trade a Legend from your Classic Team to any existing regular MLB Team!

Easy Tokens  -  Edit any team to 100 so that everyone is the best at everything. Then, start a franchise or GM Carrier. Then set the game to 162 games and customize budget (the team total cap room). Then, choose the team that you use and set their budget to the highest. When you have everything set, go to your schedule, go all the way to end season, and select "Simulate". This will simulate all your games and the reward will appear. This will leave you with about 20,000 Tokens. If you do not have enough, save your profile then shut off the game. Delete your GM Carrier or Franchise data, then repeat the steps again to buy everything.

Better fantasy draft picks  -  To get a better draft pick, keep pressing Back to go to the previous screen and press A. This will bring you back to the draft screen. Keep doing this until you get a good number.

Easy base hits  -  Put players with a speed rating of A or better (for example, Rafael Furcal, Carl Crawford, Juan Pierre, etc.) in your lineup. When the pitcher throws the ball, bunt it down the third base line and use your speed burst to get to first base. It does not matter if it is a left or right handed hitter; they will be safe 99% of the time. You can use A- players, but your success rate drops to about 90% and you must bunt it perfectly.

Fake out announcer  -  To make the announcer say something wrong, get an outfield hit with a man on second. Have the lead runner round third base when the fielder throws it. Quickly press [L] to hear the announcer say "The play at home... He's outta there!"

Easy base runners and increased RBIs  -  To get the bases loaded and increase your clean-up hitter's RBI total, use the "Easy base hits" trick. Once you have a runner on base, make them steal the next base as your hitter is about to bunt. This will keep your runner from being thrown out at second or third base on the bunt. Once the base runners are on second or third base, bunt again to load the bases. If you want to keep bunting for hits, you can send all your runners; but be careful -- if the pitcher pitches out or throws a ball and the batter misses, the runner on third base will get tagged out.

Easy wall climbs  -  First, throw a bad pitch. The batter almost always will put on a slam zone. Press A slowly. The batter will most likely hit a home run. When the Right Analog-stick icon appears, click it. If done correctly, the fielder will catch the homerun.
