Any help would be great.
Ok, the video you put up didn’t have your son pitching on it, I traced it back and found this video, I think it’s what you wanted to post.
Love the kid in center after he pitches.
Good balance on his post, he might be dropping his hips just a bit at the end of the post like to see him stay a little taller. Decent stride, may be a little short for being a pretty good sized kid. I like his arm path looks comfortable, he does need some help with his glove side mechanics, pulling the glove either to the chest or pulling the elbow back toward 2nd base.
