Slider~the killer pitch

My sons roomate had TJS. My understanding is that he was dominate in HS, with sliders and curves. Was TJS because of the slider and curve? Could be, could not be. He is used primarily in relief and as a closer only, one or two innings as he never learned to master some of the other pitches, yet.
My son is a sophmore, just learning to throw a true slider, which he will use as a show pitch only. Don't get me wrong, he did had a combo curve and slider he used as a senior, but rarely relied on it. If your son goes to college and has good mechanics, they most likely will teach the slider, but hopefully not to rely on. The curveball and slider is dangerous to young developing pitcher's arms, when used continually. If your son relies on his fastball and changeup and develops a decent breaking ball in HS, you have done the right thing. It's ok to teach the pitch later on, but not for a steady diet.
I may take some heat for this, but many overzealous parents and coaches want their players to dominate in HS, so they tend to turn their backs when sons use the slider and curve to get the job done.

Thanks Tiger Paw
He does rely heavily on FB and location.Change is getting more reliable and he is trying to get a little more velocity on his curve( per scouts request). He throws his curve about 68 mph right now and the scout said he would like to see about 73. Any faster than that and I would be concerned because then I feel it would be more like a slider. On another note our HS team will be traveling to Gaffney, SC this year and on Sunday March 26th, we are scheduled to visit Clemson and watch the game vs NC State.I hope I get to see your son pitch. How is he doing? I read earlier that he was rehabbing. I hope he is ready to go. 2 years ago we watched Clemson play Wake Forest. Great ballpark and campus.

Hoov15,
Son is fine, thanks for asking, one of those things that happen in the cold weather I suppose without the proper warmup.
Think it pretty much looks like he will be starter for weekdays and in for relief on the weekends if needed. Enjoy the game at Clemson.
