I readily admit I am not a student of the finer points of pitching. But look at this picture from cincinnatireds.com.
Don't most pitchers keep their eyes on the target, especially this far along in their pitching motion? Homer is about ready to let the pitch fly and it seems to me that he is looking upward. The camera angle could be a bit deceptive, but it really doesn't look as if he is focused on the batter (or the catcher's mitt). Is this unusual? Maybe this would help explain his lack of control. Is he looking at his grip on the ball? Maybe he sees a UFO? Someone from the upper deck waving at him is a possibility? I simply am not certain.
