26-year old righty swinging Welington Castillo and 29-year old switch-hitting Dioner Navarro are sharing time behind the plate and the results have been impressive so far in 2013. Castillo has played in 99 games for the Cubs so far this year and he is 88 of 331 (.266 avg, .704 OPS) with 33 runs scored, 4 homers, 22 RBIs and 2 stolen bases. Navarro has been a force offensively for the Cubs this year. He has played in 72 games for the Cubs so far this year and he is 55 of 186 (.296 avg, .871 OPS) with 27 runs scored, 11 homers and 27 RBIs. Navarro could be trade bait this weekend for the Cubs. That being said, Castillo and Navarro have made a nice combo behind the plate for the Cubs in 2013.
