Shadow Mario
To unlock Shadow Mario, pitch a perfect game. (unverified)
Automatic Homer
When you have Special Stars and are up to bat, hold down the R button and charge up your swing. If you manage to get a perfect charge, it will automatically blast the ball out of the park, no matter which batter you are.
Steal A Base
If you have a speedy person like yoshi, this will work best. If you are on first, you can get to second, and if your on second you can get to third...etc. Get in a run-down and right before ther player throws the ball, press Y to advance (you need to time it perfectly). If you do so, on the second or third throw you should be able to get to the base safely. This works great in close games!
