Got a still shot of my son throwing in Cary, NC. He is 14, 5’9” and 150lbs. It’s crazy to see the different forces on his elbow. No injuries or discomfort, just a crazy picture to see.
The injuries will come with this delivery. Called pole-vault pitching. Three articles that might get you thinking differently about the hazards of modern pitching mechanics (piling up strikeouts, but also piling up injuries - now that’s crazy).
