The BIGS Cheats

Start a rookie with higher stats
When you create a rookie, name him HOT DOG. His stats will be higher than when you normally start.

Easy Runs and Points
When you fill up your and your opponent fills up their point bars, wait until your opponent uses Power Blast. Strike the batter out with Big Heat and you will get 100,000 points for a Big Strike Out. You must do this a few times.

A few batters before your rookie is up, try to get base hits with them. For example, use Carl Crawford, Hank Blaylock, and Justin Morneau. If you want to do this, load up the bases if possible. Once they are loaded you should be able to hit a home run with your rookie without problems. If you do this four times you will receive unlimited Power Blasts for the rest of the game.
