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.
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 strikeouts
Change the pitching type to "Classic". Then during a game, go to the "Game Options" menu and change all of the opposing team's "Take Strike" settings all the way up and "Take Ball" down. This will make it much easier to get a strikeout. Note: This will not stop the batter from swinging. He will still swing occasionally. Additionally, throw a fastball nice and low (either side). After that, throw a change-up right down the middle (do not move the pointer, just pitch). Finally, choose a curve/slider/sinker at the bottom right or the top left corners.
Easy Tokens
Edit any team to 100 so that all players are the best at everything. Then, start a franchise or GM Carrier and set the season 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.
