Bro, pay attention. CIS is bursting with some of the top martial artists in South Florida.
@OriginalGatorHater already told you he is coming with the Mexican hook or maybe a single leg take down followed by some ground + pound.
@TLOC is using aikido mastery and style to stop on a dime and make the pitcher look foolish on his way to home plate.
@Cajuncane is half stepping it into a forearm strike to the throat... he might catch a charge on that one.
Personally, it depends on my mood. On a bad day, I'm probably going with a front flip into a falling axe kick aimed at the back of the head. Leave him with a Manny lisp for life. On a good day, a very simple judo hip toss, utilizing the pitcher's own moment to clown him, then a few back hand springs onto home plate.
Either way, just for the audacity of the attempted tackle, I'd find his sister or his GF (whichever is hotter), smash, make her fall in love, send her flowers every Tuesday (just because), make her think it's real for several months, meet all her friends and gain their approval, start looking at apartments together, and suddenly ghost her as she was waiting for me outside Applebees for dinner with her parents. No call. No text. No DM. She'd never see or hear from me again.
