Yes, the Grosser boy did have shoulder sugery, I saw the young fellow in a sling.
Although, to voice my opinion, I think the seniors up at newcath pretty much have a lock on the positions. As for underclassman, I think Chris Kelly could be getting plenty of time at catcher if not starting and the the meyer kid pitching. I can't see Seibert out playing Rawe, Rawe has speed and a good bat, not to mention a good SS, so he wont be replaced by seibert.
