I am trying to decide whether to throw a curve or a slider. I already can throw a curve and its good when I am right with it is fairly tight but I don’t have overpowering stuff and its not 12-6 its more 1-7 or 2-8. I think I should throw a slider since I have more groundball stuff and most groundball pitchers in the majors(Derek Lowe, Tim Hudson, Carmona) have sliders.
I have
4 seam- slight tail, 72, 73
2-seam- sharp, late sink 70
circle change- late fade 64
