I kneed a guy in the head a couple of years ago... I'd say I wasn't proud of it, but I kind of am.
It was a team that was notorious for playing dirty, talking trash, arguing with the umps... and this was the semifinals in the tournament. The ump actually had to call the police to remove their manager after the game that day and they were banned from playing at the parks department in the future.
Anyway, I was playing short and we had a 3 or 4 run lead. There was a runner on first and a grounder was hit to second. I got the ball at 2B and there wasn't even a close play there, but the guy running from first was coming straight at me, standing tall with his hands in the air. I'm about 6'2", and he was kind of short, so I jumped to throw over the top of him, but he kept running through the base anyway and undercut me when I jumped. I came down on top of him with my knee in his ear. I'd like to say it didn't feel good when I hopped back up and he was rolling around in pain, but when I realized he was trying to hurt me when he undercut me, it felt kind of good.


And yes, we got the double play.
