Does Long Toss Predict Throwing Velocity? DAN BLEWETT

Does Long Toss Predict Throwing Velocity? DAN BLEWETT

Backspin in long toss produces lift, causing the ball to resist the force of gravity and fly further. At the same initial trajectory and velocity, a throw of higher spin rate will fly farther. Sidespin, another variable in the equation, reduces this effect of hang time by producing a lateral Magnus force, reducing the lift of the ball.
