I’d describe this more as get your body to the glove. Your glove to the catcher’s glove; your chest to your glove. The glove should not go to the chest. Remember, we want to move forward down the target line. We don’t want anything going backward. Stay down the target line.
He seems to fall toward the 3b side of the mound. I’d like to get a head on look, but I would guess that his shin at release has his knee closer to third than his ankle. His shin should be vertical at release so that when he braces up on that front leg his weight isn’t off balance to the third base line.
He also doesn’t follow through. Lack of follow through or trunk forward flex can lead to high throws.
