Thanks JM.
I think I worded my question poorly. Since obviously the angle is different, blah, blah, I was wondering if anyone had better visual cues to determine a swing attempt from C (or B, for that matter). Different angle, but closer to the batter, etc.
In my rather limited experience I have not had as many appeals to me as BU in B or C (perhaps F2/coach thinks I wont change the call?), but I dont know why that is. I have banged out a few batters from C on checkswings, though.
Appreciate the input
