Kev asked this question I thought would make a good post topic:
"Curious on your thoughts on pitch counts in HS baseball pitchers? This past weekend our kid threw 112pitches in 9 innings of work while the opposing pitcher threw 155 in 6innings of work in the same game.We had a kid who will be drafted this year that could throw about 90-100 pitches/game and be able to turn around and do it again 3 days later. I have another kid now who can throw about 100 pitches and not be ready to go again for a week."
The low 100's at this time of year I would say is right on the money for a high school age pitcher; 155 in the danger zone. Remember, you have to count in warm up throws, bull pen, pitches between innings etc. As far as the differences in your two kids recovery wise, a lot of stuff comes into play. Physical age, training age, physical fitness, height, arm length etc. But, I think the big one that separates recovery time is throwing mechanics. And, I also believe trying to change throwing mechanics at the high school level is just as difficult to change as running mechanics. Those with lousy mechanics will also tend to "over-throw" to get the velocity they need.
