is it possible to throw a nuckleball side-arm? if so what is the best grip?
the knuckleball is a feel pitch. You need at least 2 fingers directly on the ball (finger tips) and a 3rd finger on the ball somehwere else as a balance. And yes, it’s possible. A pitcher on my team can throw a knuckleball from all arm angles. Well, he can throw it from his 3 arm angles. 3/4, sidearm, and submarine.
