With runners, the plate umpire in the OP is incorrect, and stopping a pitch is a balk.

I had a related situation as HP in a high school game with runners on 2B and 3B where the pitcher failed to come set when he threw a pitch that was fouled off. I called a balk, and awarded the runner on 3B home, and advanced the runner to 2B. My partner tried to talk me out of a balk, by saying that the pitcher is allowed to not come set with a runner on 3B. I told him that the configuration of runners on the bases is irrelevant for the enforcement of the balk rule. Because the pitcher was in the set position, and failed to come set, I called a balk.

So you are the guy that would argue that. But failing to complete the pitch is not addressed in the rule with no runners on. There is a blanket penalty you could use but most of us wouldn’t. In OBR do not warn the pitcher for confusing the batter. The batter knows what happened.
