Still reaching for waist high pitches, set the distance and/or height so that EVERY swing you take is at least arm pit high, shoulder height is better, neck height is fine also. Feel like you are almost hitting down and chopping the ball. This will put spin on the ball and they will carry much further. The post above about lowering your right elbow will also help because if you slow motion your video you will see that you are redirecting your elbow down prior to every swing. You should start with the elbow lower, and you will be in ready position to **** your swing back and power through.
