Someone, somewhere in this thread mentioned the bone in question was the hamate which makes sense from the perspective that surgery really won't repair the problem.
I remember Griffey Jr. having a broken hamate and went to look up information on his issues and found an article talking about Jr. having the bone removed which also included this line in the story,
"On May 26, 1995, Griffey fractured two bones in his left wrist while making a spectacular catch against the Kingdome’s right-center field wall. Griffey missed 73 games, but returned to play the rest of the season with a 4-inch metal plate and seven screws attached to his wrist."
Not wanting to go angry old man who talks about back in my day players didn't take days off and we don't know the full details, but when I read the comments from Alvarez etc...and am reminded that AFTER returning from surgery with a FUCKING plate in this left wrist he hit over 200 HR's in his next 4 seasons for Seattle, wtf is going on with Alvarez and I don't believe it is all the Astros medical staff.
