Catcher A.J. Pierzynski’s track record speaks for itself, with a long career behind the plate and two All-Star appearances to his name. However, part of what made Pierzynski successful was his competitive drive, and as a result he would frequently cross the line.
Pierzynski was known for frequent arguments, trash-talking, and getting under the skin of opponents. In 2006, after being tagged out at the plate, he aggressively bumped into opposing catcher Michael Barrett, prompting Barrett to punch him in the face and subsequently sparking an epic brawl.
