Ok is is possible to throw a knuckle ball 80-90mph with no- or little spin and alot of action, break on the ball
:shock: Man. If you could throw a knuckleball 90, I'd LOVE to see your fastball!!
With a touch of vaseline, anything's possible.
According to the laws of physics, no. At least not by any human being. If your knuckleball is at 80 mph, your fastball would have to be 120 mph or so.
according to Ellis, you need to throw a knuckle ball around 66-68 mph to get the right "knuckling" action on the ball
ohh u people think i throw a 80 mph knuckle lol what eva. no i dont, its only about 50mph
