Is the discussion by some to suggest that a screwball can only travel on a flat plane?
Sluggers and I have $100 each to give anyone with video proof of a 3-9 screw ball (RHP) that breaks. I’ve seen a handful of scrops, but never a screw ball that wasn’t anything more than drive left and throw right.
I'm not sure if you are talking about the slo-mo starting around 0:17 or not. For clarity, the slo-mo looks to my eyes to be 3 to 9 rotation. For a RHP to a RHB that is screw spin. As for the first two "live action" pitches, they are obviously too fast to see the spin, but I'd hesitate to call the first one a curve (unless maybe trying to throw a back-door curve).
