 You know, one of the hardest. One of the hardest pitches to hit is a backup. Curveball or a backup slider and I'll tell you what I mean by that in a second to one off the plate three and one. You know, obviously these guys are trying to really get that tight spin on a slider or curveball to get it down, bury it or throw it down low, get you to chase. But the one that just spins and kind of. Never comes down. Oftentimes is the one that gets the weirdest swings and the easiest lightest contact.
