I sat behind the bullpen the other night and I thought Berrios looked like someone had shot his dog. He generally look miserable.
My gut says there might be something minor wrong with his elbow (bone spurs). If they needed him to pitch, he'd pitch through it, but they don't, so off to the IL he goes...
Wouldn't be surprised to see him get some type of clean up arthroscopic surgery on the elbow his offseason. Hopefully it allows him to rebound next year.
