CD I have to disagree with you on who should listen. Perfect for the serious high school player, in fact every serious HS player should have the audio CD on his iPod. My son listens to it prior to games, usually every away game since he has the time in the car/bus, he LOVES this guy. He has seen him a couple of times at Jaeger camps and the guy is even better in person.
Funny story, he went 1 for 4 a few weeks ago and one of the coaches was ribbing him about it and he looked the coach straight in the eye and said "coach you are wrong, I had 4 quality at bats and hit the ball hard 4 times, I can't do anything about what happens after I hit the ball, particularly if I hit it hard." The coach looked at him and said "you know what you are right" and walked away.
