Zach Duke and minor league shortstop Brock Holt are both facing new injury troubles. Duke is describing his injury--a muscle strain around his pitching elbow--as not particularly serious, and it sounds like the plan is to have him miss only one start. But elbow injuries are always scary for pitchers, so this bears watching. Holt has a torn MCL and will miss at least six weeks, according to the Post-Gazette. He had been out of the lineup for a while, but I don't think I'd heard before today what the problem was. Surgery is supposedly a possibility, so I wouldn't be surprised if he missed the rest of the season. Which is a shame, because Holt really hit well, posting a huge OBP for Bradenton despite 2010 being his first full pro season. When you draft a guy from a major college program like Rice, you hope that he can really fly through the low levels of the minors, but Holt is one of those rare guys who actually did it. And then this happens, and it slows everything down considerably. UPDATE: Rob Biertempfel is now reporting that Holt's MCL is not torn and that he will not require surgery. I'm not sure what happened, but this is nice news.
