Is a Swing a Strike?

[Shmuelg]

Men's FP, although this works with the women as well, and even in baseball.

Count is 1 and 2, no outs, no one on base.

Pitcher throws a helium-ball (very very high), impossible to hit or catch, and it goes to the backstop. Batter, being shrewd, swings when he sees this. He didn't "aim" at the ball, it was obvious that he was swinging to get the "dropped third strike" situation. He then runs to first, and gets there safely. PU (I was FU) says it's a ball, and calls the batter back. Batter doesn't like this, and says he swung. Defense does NOT appeal the call, btw. I supported the PU, based on the understanding of the rules that a strike is to be called when the "batter strikes at the ball", and he didn't strike AT THE BALL. That's why it's called strike, Maude.

OK, what do you guys say to this? Good call? Bad call?
