AH a knuckle ball is pretty easy to throw if you have someone who can throw it right show you. my knuckle ball has gotten better since highschool because ive busted more fingers and they are all crooked. really helps w/ the movement. and yea im sure that your arm hurts from throwin a screwball. mine does everytime. i never throw them any more or i wont last 4 innings. once in a while ill throw one to a lefty batter after throwin a 6 to 12 curve. ide say my most reliable pitches would be 2 seem which tends to tail high and right. and my change w/ a 6/12 curve a 2/7 curve will get driven everytime in the league i play in. its all they see. and it pretty much goes w/ out sayin if i throw a knuckle ball that becomes a silvaneer for someone lol i cant throw it w/ any velocity
