He wanted shoulder and neck high pitches called a strike.
He constantly asked the catcher where a pitch was (answer “high” each time).
He came out of the dugout once to ask the PU when the catcher shrugged.
He wanted an automatic base on an obstruction.
He objected to the BU confirming a catch on strike 3. Same on a missed tag.
He wanted an out on LBR when the pitcher faked a throw.
You would think a 16&U coach would know better by now.
His manner was irritating most of the time.
He kept announcing the count of calls/rulings he disagreed with.
Yes, probably too patient, and you probably will say so; especially for the next crew. Thought he would go over the edge any moment; making it him, not umpire feelings.
p.s. the opposing coach was a model of patience and understanding.
