Nice knuckleball...but, I'll probably think twice about eating a hot dog while watching a pitcher throw one .

LOL,I played baseball in HS and we played in state tounament one year.There was a kid on one of the other teams that threw a screw ball. Scared the shit out of me everytime I came up to bat. His team wasn't that great but they won the tounament because of that kid.

Yep . Hard pitch to hit. Phil ' knucksie' Niekro pitched into his 40's throwing that thing. NASTY!

I played High School baseball too, I caught and loved it. We didn't have any pitchers that threw that kind of stuff though...lucky for me .

The catcher actually ducks his head outta the way and he is a specialty catcher that only catches the knuckle ball guy!
