I did once. I’m ashamed to say it. My girlfriend was at the game and I told her I was gonna hit someone, thinking it’d be cool. I got him right in the helmet. Luckily it didn’t hurt the guy at all. That was when I was young.
Last year, as I was taking my warmup pitches, the ondeck batter was standing too close to the batters box, watching my pitches. I really wanted to nail the guy and at the last minute as I brought my arm around I thought “uh, better not make it too obvious” and I bounced it right at his legs.
He looked at me and said " I thought you were gonna do that."
I said “woops. Ya better be careful.”
But then he didn’t back off on my next warmup pitch, and it really got to me.
I ended up walking him on 4 pitches, cuz my focus was so jarred.
