Regardless of eveyone's medical background, the facts remain... 1) This problems started on 3/25 2) It took 3 weeks to get him on the DL 3) Within a few days, the diagnosis has changed dramatically and for the worse. The most likely explanations seem to be: 1) that Mastro is REALLY good at hiding the problem, which he might be, but it's not like they didn't know he was injured. They openly talked about how limited he would be and when he could come back to the lineup. Or... 2) that he wasn't all that bad, but it got a lot worse. Well, yeah, that can happen when you continue to play on an injury. And if it was one time, that would be fine, but it happens over and over. Baker, Pavano, Span, Plouffe, Morneau... and that's off the top of my head.
