Good contact. However he could hit the ball harder if he lets his hips open up more after contact and follow through. My kids were taught load, stride, contact, follow through and extension. After glancing at this I noticed he was stopping his hip rotation and follow through. There are a bunch of drills out there to help with that. I'm no hitting expert (all 3 of my kids were pitchers), but that did catch my eye.
PS....The catchers reaction is hysterical. He has no clue where the ball is. ;-)
