As Joba Chamberlain was busy walking everyone and their mother in Friday night’s Subway Series opener, Jorge Posada was busying visiting the mound between what seemed like every pitch. Yesterday, the two acknowledged the obvious: They were having trouble communicating, mostly about pitch selection. Posada said he was trying to speed Joba up to improve his tempo, while the pitcher said he was out of rhythm. As much as we all love you Joba, you’re 23. Listen to Jorge.
