Batter hits pitch that hit ground

[mcrowder]

The swing may be quick, but the ball may not be. I think that's the clarification...

Pitch ... bounce.... swing is one scenario.

Pitch ... start swing ... bounce just before the hitting or missing of the ball - this is the scenario in question. Sounds like you (MikeR) are calling strike whether the ball was hit or not here. Don't the rules say it's not? Can you really call it a strike if they hit it, but then not allow the hit to stand?
