33-year old lefty swinging A.J. Pierzynski just keeps rolling along for the White Sox. He played in 138 games for the White Sox last season and he was 151 for 504 (.300 avg, .756 OPS) with 57 runs scored, 13 homers and 49 RBIs. Pierzynski is a very dependable hitter for the White Sox and there is no reason to think he won’t be again in 2010. Pierzynski made 5 errors and he had 7 passed balls in 131 games behind the plate last season. He only threw out 17% of the runners trying to steal against him last season but White Sox pitchers had a 4.10 ERA with him behind the plate. Pierzynski will be a asset to the White Sox again in 2010.

33-year old righty swinging Ramon Castro will back up Pierzynski in 2010. He played in 57 games for the Mets and White Sox last season and he was 34 for 155 (.219 avg, .698 OPS) with 13 runs scored, 7 homers and 25 RBIs. Castro has big time power so he will likely help the White Sox off the bench in 2010. Castro made 5 errors in 52 games behind the plate last season but he didn’t have any passed balls which was impressive. Castro has a better arm than Pierzynski does as he threw out 25% of the runners trying to steal on him and pitchers had a 4.41 ERA throwing to him.

It’s only a matter of time until 23-year old righty swinging Tyler Flowers is the full-time catcher for the White Sox but it won’t be this season. He played in 108 games in AA+AAA-ball last season and he was 105 for 353 (.297 avg, .939 OPS) with 67 runs scored, 15 homers, 56 RBIs and 3 stolen bases. Flowers also made his major league debut last season for the White Sox as he played in 10 games in which he was 3 for 16 (.188 avg, .600 OPS) with 3 runs scored but he whiffed 8 times. Flowers didn’t make any errors or have any passed balls in 6 games behind the plate for the White Sox. He was 0 for 2 throwing out base stealers and White Sox’ pitchers had a 5.67 ERA with Flowers behind the plate. In time, Flowers will be a good catcher in the majors but he won’t really get his chance until probably 2011 as the White Sox are set to go with Pierzynski and Castro in 2010.
