Over at Fangraphs, they're doing a neat recap of the best pitches of 2011. Madson makes the honorable mention cut for his changeup.
Ryan Madson: I didn’t include a reliever on this list until now, but RHP Ryan Madson got some serious results with his changeup with a 55.8% whiff rate and 14.9 wCH, both leading all relief pitchers. It’s a changeup that dives down and runs at about 84 mph. As a mostly fastball/changeup combo reliever, he used his changeup as much as anybody in baseball (34.4%).
