What he demonstrates slowly appears to be a change with curve rotation (crange.) Shown at full speed, the hand seems to be behind the ball. Can't see the spin, but he's locating it pretty high and inside (RHB.) I'll ask a buddy to see if he can translate.
What is a good batting average for a top level men's FP player? .200? How can anyone hit that? Looks harder to hit than MLB.
