kinda more like a slider? do you have a pitching coach on your team? if so, have him teach you how to throw a curve. or get it touch with a pitching coach in your area. and you will dominate this spring. i only throw about 70-75, and have little movement on my curve, but a great change-up. they cant touch my change, and i had a 1.20 era this past hs season. im a seinor this year. if you can throw your change and fastball for strikes, and drop that knuckle-slider pitch in there every once in a while, mainly using it for strike out pitch, you will do very good.
