Happy Birthday, AJ Pierzynski! From your first All-Star appearance with the Minnesota Twins in 2002 to swinging your way into a Silver Slugger Award in 2012, you've always been a catcher who knows how to make headlines—on and off the field. Your legendary ability behind home plate was matched only by your knack for stirring up some good-natured trouble.Here's hoping this birthday is as memorable as those epic moments when you called pitches like a psychic and swung bats like Thor's hammer. May you celebrate today with fewer collisions at home plate—and more cake on yours!
