Helsey’s curveball clocked in at an average speed of 81.03 mph, but would occasionally dip into the mid-70s to give him a nearly 25 mph difference between his fastest and slowest pitches. His K/9 numbers were down in the majors, dropping to 7.85 from 9.88 in AAA last year, but with that much of a speed discrepancy paired with improving control, that could turn back around.
