Batter Hitting Catcher on Backswing-Repeatedly

[SAump]

Ozzy mentions a practice swing. I did not mention anything about a practice swing or warmup swing. I thought the rule violation took place during a live ball after the batter swung at a hittable pitch. But here you go.

A warmup swing may be as hard as a home run warmup swing a batter may take in the on deck circle or the short plate measurement half swing and soft backswing usually taken in the batters box. The catcher is standing TOO close to the batter.

Now easygoer doesn't mention a warmup backswing, so his catcher is subject to catcher's interference. But he claims to know what that is and states that that did not occur. I have nothing here so I asked for more info.
