Koji Uehara's horrific run last August and September was apparently not due to fatigue—as had been previously thought. It has now been revealed that Boston's closer was experiencing back pain during that period that forced an alteration in his pitching mechanics. Said Koji, "I didn’t talk about it at that time. I think I’m over it. I’m not going to go into specifics, but it wasn’t fatigue." Despite being yanked from the closer role last year, Uehara is expected to regain that status in 2015.
