I would like a rating on the mechanics here, the only thing I can think of is his right back leg, but other then that what else needs critiquing? He’s 11 and can sit at pitching 58 mph.
Looks good! I would like to see a more aggressive transfer of his weight from the back foot to the front foot, which would help to lengthen his stride… but good stuff! Keep it up!
I agree with Steven. I would also eliminate the head movement toards 2B - you don’t want any of your weight going that direction. Let the hips move out first while the head stays still for a moment to get into the “led with the hip” position. You may find that moving forward more aggresssively may eliminate the rearward head movement.
