Ivan Rodriquez officially retired from Major League Baseball Monday night, after 21 years in the league.

Pudge won the AL MVP in 1999, and won his first World Series in 2003. He may be the best defensive catcher to ever wear a Major league uniform, and will almost certainly be a first ballot Hall of Famer.

Is he the best catcher of all time? Here are the five best catchers in MLB History.
