If a player or coach requests the number of outs, how do you signal it? On your right hand? Left hand?
What if there is no scoreboard, and you periodically give the number of outs? Both hands? Up high? To your sides? Does it change if you're behind the plate or on the bases?
Kind of a mundane detail, I know... But one that's never talked about. At least, not at any clinic or NUS I've ever been to.
