For you pitching experts, how does JT get that hard sink and run? Is he rolling his wrist over or is it simply from pressure with the fingers? If ya’ll think back, Bobby Reed had a hard sinker and was almost unhittable as a freshman but tore his elbow up. I know a guy who pitched in the majors for a short time. He threw slow frisbees to the plate but hurt his elbow, came back with much less movement and was out of the game because he wasn’t effective anymore.

I rambled but could the problem be the hard movement that JT is creating?
