Add my son to the list of last minute cancels. Apparently he had been playing with a fractured hook of the hamate bone in his left hand for a while (he's a RHH). It finally got to where he couldn't grip the bat during D3 Regionals. He started every game of the season up until that point.
He had a CT scan last week and today the ortho says it's a "nondisplaced" fracture and put him in a cast for 6 weeks. Son begged the doctor to just remove the bone, but the doctor said he would not take on the risks involved with hand surgery just to speed up his return for summer ball. The doctor didn't rule out playing immediately after the cast comes off, but the summer season will be almost over by then. This was going to be my son's last season of summer ball, and he was really looking forward to playing in the Valley League. Needless to say he is terribly disappointed.
