Oakland Athletics pitcher A.J. Griffin plays guitar before his starts. "When everybody is doing batting practice, for me there's nothing better to do than just hang out and not think about anything before I pitch," Griffin recently told ESPN. "I like to chill out, relax, and mess around with the guitar." He also plays for his teammates, keeping the clubhouse lively with Led Zeppelin and Spanish standards. "We play well as a team when we're all loose and enjoying ourselves," he says.
