A Brief wOBA Allowed Leaderboard by Dave Cameron June 12, 2014 In the research for the piece I just posted on Johnny Cueto, I ended up with a treasure trove of data on pitch type outcomes during the PITCHF/x era. It is really fun information, and so I figured I’d share a few tidbits here that don’t necessarily lend themselves to an entire post. This post is basically just a list of interesting numbers without any commentary. Enjoy! First, here are the 10 lowest wOBAs allowed for all pitch types for starting pitchers in 2014, setting a minimum of 100 pitches thrown for each pitch type. Pitcher Pitch wOBA Julio Teheran Change-Up 0.059 Collin McHugh Curveball 0.093 Julio Teheran Curveball 0.099 Chris Sale Slider 0.100 Gio Gonzalez Curveball 0.123 Josh Beckett Curveball 0.128 Hisashi Iwakuma Splitter 0.131 Corey Kluber Curveball 0.131 Masahiro Tanaka Slider 0.133 Masahiro Tanaka Splitter 0.140 Keep in mind that there’s a huge selection bias here, in that breaking balls and off-speed pitches get thrown primarily in pitcher’s counts, when the expected wOBA is much lower. So, you don’t want to say that Colin McHugh’s curveball is the second best pitch in baseball. It’s not. But it’s been a pretty fantastic out-pitch so far this year. And now, the laggards, though we’ll only do bottom five in order to limit our the amount of public shaming. Pitcher Pitch wOBA Sergio Santos Four-Seam 0.639 Edward Mujica Four-Seam 0.617 Sean Marshall Slider 0.602 Jhoulys Chacin Four-Seam 0.596 Eric Stults Curveball 0.592 Maybe time to mix it up or just try something else entirely, boys.
