That game would be perfect for the iPhone, since all you do is swing and pitch.
I went with games that are easy to control. Here's what I have:
RBI Baseball (a bit hard, but I am an addicted pro at that game, modded to 2007 rosters)
Zelda
Monopoly
Tetris
Dr Mario
Excitebike
What's your team? I use two skinnies and a fatty.
