From Gamespot:

[Joel] Zumaya, who tops the 100mph mark on his fastball, was benched in the ALCS against the Oakland Athletics because of forearm inflammation. However, the Tigers training staff was confused because his injury seemed to be caused by the same motion of playing guitar--not from an overhand pitching motion.

Apparently, Zumaya is a Guitar Hero addict and was playing it so much that he was injuring his throwing arm. His trainers told him to stop playing and he was able to pitch in the World Series. Guitar Hero is fun, but to play it so much you hurt your arm? Yeah... I can understand that :)
