Fantasy Impact - While the catcher position has been relatively weak recently, 2014 looks better than it has been in a while and Pierzynski should fall in ranking to about the 12th best catcher available. He warrants a draft pick in 12-team leagues or for use on a team looking for a decent utility player (not 1B eligible).
Predictions - .270, 55 R, 15 HR, 62 RBI, 18 BB, 75 K, 0 SB
