ATHLETE: ROGER CLEMENS
MOTIVATION: Consistently getting owned by Mets slugger Mike Piazza.
MOMENT OF VENGEANCE: In one of the most high-profile acts of ‘roid rage ever, Clemens inexplicably throws a piece of a shattered bat in Piazza’s direction'this just a few months after beaning him in the head with a baseball. Yo Rocket: Don’t be mad at Mike ’cause your balls are the size of BB pellets.
