This was also covered at the National Umpire School I attended last year.

I had never given much thought to this until I was at a high school baseball clinic about five years ago. During some plate drills, one of the umpires used his left hand to signal "don't pitch/hold up play" when there was a left handed batter. The instructor about had a cow. Dressed the guy down pretty good for using the "wrong" hand. Sure enough, baseball mechanics are to always use the right hand.

Since this incident raised my awareness of which hand I was using, the ASA instruction about switching hands based on the batter has always stuck in my mind.

You should see what the baseball guys do when someone hollars, "DEADBALL"....
