Before I read Reluctant O's post I was thinking the exact same thing. There is a ton of power waiting to be tapped into. My son used to have a very similar swing. At times it almost looked like a golf finish. The tips his hitting coaches are always giving; stay in your back hip, stay back, and stay down. They do a "knee down" drill where you swing and finish with your right knee on the ground. It is much better to do with soft toss than a tee. It was very awkward at first but now it's one of my son's favorite drills.
