Karst commands a sinker and slider exceptionally well, tunneling the two pitches to keep hitters off balance. His sweeping slider averages 19 inches of horizontal break and has generated a 44% whiff rate. (2/3)

Jack Karst (@karstjack) has been one of the most efficient arms on the mound this summer. After pitching for @Delta_Baseball this spring, the uncommitted right-hander has frustrated hitters from both sides of the plate, posting a 2.10 ERA and a 1.08 WHIP. (1/3)
