Hint: In a single-player game, choose a team with a high rating when you start off. If the AI gets the Yanks and you got the Cubs, chances are you're in for a long day at the old ballpark.
Hint: In two-player mode, play "Billy Ball" and run the bases like a banshee. But don't rely too heavily on the basepath meter as it's not quite to scale.
Hint: Mind the infielders and swing for the gaps when you've got runners aboard.
Hint: Always keep an eye on your pitcher's power meter. As soon as 1/3 of it is orange, it's time to get somebody working in the bullpen.
Hint: If you time the jump just right, you can steal a homer--but you've got to be really good.
