ESPN Major League Baseball Cheats

Stealing bases:
99% of the time, if your lead off hitter is fast enough he will be able to swipe a base, but if the other team has a cannon of a catcher stay there. If you are a rookie, try not to lead off because it is difficult to get back on base not getting off. 

Better homerun chance:
Hold Left Analog-stick Up for a better chance of hitting a homerun. This works well when using a power hitter such as Carlos Beltran, Manny Ramirez, A-Rod, Barry Bonds, etc.

Easy perfect game:
Go to the game play setting sliders and go to "AI batting". Set everything to 100 and the CPU will never swing the bat.

Running into the catcher:
While running home, hold Square and the baserunner will knock the catcher over, and possibly drop the ball.
