The Yankees announced this afternoon that Joba Chamberlain is headed to the DL with a strained elbow flexor, and I'm not the least bit surprised that something is wrong with him. Below are the average velocities for his fastball, slider, and curve over each 2011 appearance. Take a look at the last two:
This one is all fastballs:
You can see that in his past two games, his velocity was down about 3 mph from where it usually is. It looks like he won't throw for two weeks, so I wouldn't be shocked if we don't see him back on the team until July. That's disappointing news.
