Perhaps Compton or whoever he was signaling in calls to had poor eyesight. When I was a catcher in HS baseball, we had a pitcher who's eyes were so bad he couldn't see my fingers. I faked giving signals then either used and open hand or a fist to call the pitch.If I remember correctly he hasn't done it since he's been here - first off because he wasn't DC, and second because I remember earlier last season he didn't have the tape, and went to it starting with (perhaps) the Wisconsin game?
