Marshall mechanics Tyler S. Pronated curveball

This is Tyler S. 13 yo pitching a pronated curveball.
This is a very difficult skill to acquire to make this pitch pronation driven to protect the elbow against ballistic elbow crash always associated with supinated curves like knuckle, Karate chop or 3/4 curves traditionally thrown.

I have 2 questions that I was wondering about Marshall pitching: Why is the Max. Pronation Curve so hard to throw, and is there a Torque pronation curveball? That was a great curve by the way!

The articulation is not difficult if you throw from inside of vertical, produced from Marshalls over all approach, as soon as Marshall pitchers loose this angle they then supinate also. The trick is to get your elbow up at the back during the Marshall transition then driving the ball with your hand on top and the fingers rotating the ball like a draddle that actually wont happen by producing 12/6 rotation. Two of my older clients produce overspin. You can throw this pitch from either side.

@dirtberry

have a high speed of my latest students pronation release. note pronation as hand goes out of frame.

This ball has a nasty late break. He hit 95 this summer at 17 years old. He now is at Bucky Dent and they will probably ruin him....
