I had this play a few years back, big night game between cross town rivals. The game was tied in a game the visitors were supposed to winning big and the home team steals home. R3 slides headfirst to the infield side, the batter checked his swing, and the catcher tried to go behind the batter and tag the runner. I had a safe call and a very upset manager. If you want to see the manager look on the rulebook cover.
Anyway, he wanted the runner out on interference and I wouldn't give it to him. I explained exactly what I've said here, the batter is allowed the chance to swing. Just being there isn't a violation. The manager wanted me to go to my partner for help. I gave him the "Have you lost your mind" look and told him there was no way I was going to do that. Of course my ruling carried the day.
With it being a big game and a night game the place was packed and there were at least 6 to 12 mid to upper level umps behind me. Some agreed, some thought I blew it. After the game we had a big meeting at my truck and I convinced the naysayers I was correct and that they were misapplying the rule. Once they understood why I made the call they all agreed.
