I might be naive or just overly optimistic, but I would think if his arm or shoulder were bothering him, the Twins would shut him down. But, yes. The performance thus far is worrisome. Could be mechanics, could be confidence or a combination of the two. Whatever it is, he doesn't look right. Hopefully nothing injury related and he starts to round into form. The Twins can't win the division or wildcard spot without Duran being himself.
