I just read that the University of Kentucky baseball team will have two left-handed catchers on its roster this season: Tyler Howe and Ross Hubbard. This got me to thinking about how rare left-handed catchers really are. I have never witnessed one in action.
The last one in MLB was Benny Distefano, who caught three games for the Pirates in 1989. There have only been 33 left-handed throwing players who caught in at least 1 defensive inning. If you exclude the ten men who only caught in a single game, then you're talking about just 23 players. If you count only those guys who caught a 100 or more games in a career, you're down to exactly five left-handed throwing catchers. However, if you're only counting career catchers (minimum of 1,000 games caught), then you have exactly one and that is Jack Clements. (source)
So, why aren't there more left-handed catchers?
