STATS and Yahoo! released some interesting swing and miss rates for various pitches, and Sergio Santos and Ricky Romero made their lists.
STATS discovered in their research that Santos’ slider was whiffed on a whopping 62.2% of the time, the second-highest of any pitch in baseball outside of the 68.8 % from Jonny Venters’ slider.
Yahoo!, however, said that Santos’ slider, while still the second-highest, was whiffed on by batters a much lower 34.52% of the time. Romero’s had the 18th-highest curveball at 14.89% and his changeup ranked seventh at 23.79%.
