Pitcher Hits Batter With Pitch, Batter Whips Bat At Pitcher

I played baseball all through high school and never once saw an HBP that seemed remotely intentional. it just doesn't happen much.

Yea I know of multiple occasions of tossing at a batter over my time playing ball

You serious KG6? I pitched. Hit 2 guys intentionally that i remember, and it wasn't for something that happen in a baseball game. Didn't like those guys from playing basketball against them. Game was in hand for us, they came up to bat, threw it as hard as i could at their back. Pretty sure they knew it was coming.
