Being 14 a slider could destroy your arm. And I beg to differ. I am not giong to contradict you kelvin this has nothing to do with the other topic. Heres a post I've been wanting to make. Regarding the cutter.
It is a mental pitch more than a physical pitch. If you don't believe me then how come a major league batter, the best of the best, can't hit Marino Rivera? He's let up like 2 runs all year. These are the best hitters in the world that can't hit him. They even know that its coming every single pitch.
This is what the cutter does. You throw it RHP to a RHB inside. First pitch if you can locate a cutter they won't swing unless they're a crazy first pitch hitter. They'll think its a ball next thing you know its a strike. I throw my cutter almost more than my fastball. The hitter gets a bit confused. Then I throw it outside or even inside again. This can really fool with a hitter. Use the mental aspect. Ever realize how hard it is to adjust to a very bad umpire? One past Major League player said that if the umpire didn't call it in his zone he didn't care he only swung when it was in his zone. Becuase it is incredibly tough to change habbit. So this pitch can be used as a mental pitch. This year I pitched an inning and the next inning both coaches were on the grass by the infield looking at me and watching me. Because their hitters were baffeled. Now unless you throw a 94 MPH cutter like Mo, this won't be your KO pitch. Most likely. Your going to need a nice hammer or change-up.
But kelvin is correct. The cutter is a tough pitch to use if you don't throw very hard. Heat is nice but you don't have to have have the heat for it. You can throw this with a good 2-seam or sinker. It compliments very well.
If you face good hitters its a good pitch to use because he will be picky. If you can locate this first pitch. You will be ahead every single count. Once they see that your fasbtall moves, a great atbat is inside for a called strike. Just catching the plate. Then get it even more inside and get him swinging at a bad pitch or something. If you can get 2 strikes, go with your KO pitch.
