The good news is if he has to miss a month or two, he , Robert, Eloy, all should be pretty strong at the end of the season and the playoffs when other guys are probably dying. Could be huge.
It looked terrible because he was in a lot of pain, but the physical act that caused it to happen was minimal. Hopefully that keeps the severity down. It wasn't like he was busting his ass going somewhere, he just took a pitch That calf muscle couldn't have been as engaged as it would be for other things.
I am not a medical professional, but I am thinking even if he had sat out a week, that calf was a ticking time bomb and the same thing was going to happen. There really was no good answer IMO.
