For pitches with 250+ swings, Buchholz's changeup is 3rd with a .462 whiff rate (behind Hamel's changeup, .480, and Marmol's slider, .465). For only pitches in the zone, Buchholz's change is 1st for pitches with 250+ swings at a .413 whiff rate, above Hamel's change at .355 and Marcum's change at .352. That's insane. The whiff rate on Buch's change in the zone would be 13th in whiff rate when compared to other's pitches thrown anywhere. Conclusion: Buch needs to throw more changeups, and not be afraid to throw them in the zone.
