Additional warmup pitches during defensive coaches rules discussion

[moorg]

Top 3rd. One out, R2. Defensive coach comes out to discuss substitions (he's bringing in a new outfielder but must not have had a clear "18 in for 23" situation, it took quite a discussion).

During this conversation with the plate umpire the pitcher from the rubber gets in several additional warmup pitches. Any problems with this? This was a Fed game but I wouldn't find hearing from any book.

I hope this doesn't have the same fate as the Coach Bringing Ball onto Field During a Conf thread.
