No, I didn't run him

Ace,

As I read (and re-read) your OP...it just seems to me that the HC had a brain fart...nothing to be tossed for.

As I have moved from being "just an umpire" to "umpire and umpire association President" I tend to view these types of posts with two eyes: (1) how would I have handled it if it was me umpiring AND (2) can I (as President) defend "my umpire" with a straight face to a league President who wants to know why "my umpire" (insert: ejected a coach; or made such a ruling; etc.).

As a President of an umpire association I will say this:

Frankly, if one of my umpires did toss this coach after this play and your OP served as my umpire's ejection report...I'd have a tough time defending you to the high school league assistant director for baseball when said assistant director calls me wanting to know why the heck my umpire tossed a coach for simply touching a live ball.

Good move not tossing him (unless there were some other acts committed by the HC that were left out of your OP).

"TIME. THAT'S INTERFERENCE BY THE COACH".

I don't think any coach would want to hear that said loudly. Business is taken care of. Play ball.
