Looks great for his age. Hip and shoulder are coming through at exactly the same time( no seperation). Gonna have to work on that to get faster. When the front foot turns to land, it begins the delivery. Front foot turns to land, front hip snaps open, which rotates your torso, shoulders then follow the torso, and arm follows shoulder on a fastball the wrist snaps downward on release creating backspin off the middle finger. But honestly he looks great for his age.
