Tyrell Jenkins, high school pitcher

The short stride with his front leg leads to the rest of the delivery looking herky-jerky, since it leaves him with too little time to circle the ball back into the driveline. He compensates by not bringing his hands low before they break and picking up the ball with his elbow. Neither is a huge red flag, but they are things he’ll likely need to fix in the professional game.

The thing that really worries me, and its not even really for injury reasons, is how far behind his back he brings the ball. Its clearly going to be visible to hitters, and as he starts facing more refined ones they’re likely going to be able to pick up his grip, and thus know what pitch is coming, before he ever releases it.

As for the positives, I really like the front side mechanics. He does a good job firming up the front side and tucking in his glove side arm. He seems to pronate well at release and I don’t see any red flags with his arm deceleration.

Overall I think I like what I see. He certainly needs some work, but what HS pitcher doesn’t? I think most of his current issues could be fixed with a longer stride, which gives the arm more time to get into proper position and should help him generate a little more velocity without adding extra stress to his arm.
