In the ninth inning of last night's game Hanley Ramirez hurt his shoulder while swinging at a pitch.
I had a friend do this and it continued to be a problem for a very long time. His shoulder kept popping out and in when he tried to exert himself. I guess that would be okay if you were Houdini or the Martin Riggs character in the Lethal Weapon series, but it would stink for a ball player.
Hopefully that won't be the case.
