Hey, this guy has some serious mechanics happening. Good job. Nice rotation, well balanced. Now, a couple of suggestions.
His “rocker step” with his left foot in the windup is forward. As he gets older, or in tournaments, he might get called for a balk. The rules state that you can take one step back and one forward. Depends on the ump at this level.
Another thing the forward step does is force him to stop that forward movement of his centre of gravity with a momentary pause, then go backward to get up to knee lift where he has another momentary pause, then throw. Try to eliminate the pauses. Get his left hip going toward the target no later than at the top of the lift. Don’t fall for the “pause at the balance point” cue that so many coaches recommend. What purpose does it serve other than to stop movement? Due to that pause at the balance point, everything that preceded it is just for looks. You might as well just start at the balance point. It just negated everyting that came before.
Many people say that, at this level, you should stick to the stretch rather than the full windup because it simplifies things. This might be true but I think this kid can handle the windup. He’s doing very well already.
His glove side should be worked on a bit. It turns over and drops early. Actually, it never really gets up at all after it drops with the hands breaking out of the glove. It sweeps at hip height and stays down there. It turns over early which has the effect of pulling the front shoulder open with it. Early. Watch some of the videos in the library on this site for lead arm action. Chris and I have been having a running debate about the oft recommended “point the glove at the target cue”. I really dislike this one. I prefer what guys like Nolan Ryan, Roger Clemens or Kevin Brown do with the elbows. These are all to be seen in the library.
He’s sweeping the ball hand down and back behind his body before arcing it up in back. I would suggest that he get a slight bend in the elbow at about 7:00 when looking at him from the 3rd base side. Then he should lift the forearm up instead of circling way back behind him and up. Again, the library would be a great place to research what the pros do.
Lastly, he’s really sticking a finish position here but I’m afraid for his safety with his glove back by his hip and his head out front like that. Get his glove tuck to be to his chest, not his hip.
All in all, he’s looking quite good but some small adjustments will do him well. Nice job.
