Its rare to get arm-side run with a 4 seam grip, but hes a super rare pitcher. Think they call that "the running fastball" (arm side run with a 4 seam grip). Its got less verticle drop than a 2 seamer usually.
Kind of funny, how if it runs arm side with no drop, its a running fastball, wiht some drop its a 2 seamer, but not too much drop becasue then its a sinker.
King of like 1-to-7 oclock is a curveball, but 12-6 is a 12-6 curve, but 3-to-8 is a sweeping curveball
So many different names and more are added every year.
