I'd really appreciate help. I'm a single Dad and working with my son(s) on baseball is my primary window to get to spend time with them and support them. I am a former D-1 athlete (swimming) and have experience in biomechanics. I'm hoping that with this forums support, I can level up enough to provide my boys solid base mechanics.
This is Evan. 12 years old. 5'10" 145 lbs. He is likely to grow into a big guy. I'm 6'4" and there is a lot of size on his mom's side. At same point on growth chart at 18, he would be 6'7" 230. I don't expect that but I don't think 6'5" is unrealistic.
Evan has pitched 40 innings or so each of last two summers. He's not had any pitching specific coaching outside what I've been able to do this past summer. This is where we've gotten.
Using an accurate timer on an app and a formula on the side view pitch (video is cropped), I calculated his avg speed from release point to front of home plate at 65.8 mph. Has good control and keeps the ball down.
I've just taught him the curve and slurve/slider in the second video. Looking for feedback on those pitches. No change up yet but looking into it. Has only thrown 4 seam CB in games to now (season over).
My first post and I really appreciate you reading all of this and looking at the videos. My focus is to try to prepare him for a shot a HS ball (in Ky). He hit over .400 this summer and plays a strong 1st as well.
Two videos (side view and catch view).
