We are looking at which pitchers have the largest discrepancy between their fastball and change-up average velocities.
For our sample size, we are taking all pitchers who have thrown at least 20 innings this season and thrown their change-up at least 8% of the time. Sure, that is an arbitrary number, but I feel like if someone throws 100 pitches in about 8 innings of work, they should at least throw the change-up, on average, once per inning.
According to Fangraphs, this left us with a sample of 152 pitchers.
National League
Marco Estrada, Brewers 90.6 - 76.8 = 13.8
Erik Bedard, Pirates 89.1 - 75.9 = 13.2
Craig Breslow, Diamondbacks 90.6 - 77.9 = 12.7
Tyler Clippard, Nationals 92.8 - 81.6 = 11.2
Brandon Beachy, Braves 91 - 80 = 11
Johan Santana, Mets 88.4 - 77.8 = 10.6
Chris Capuano, Dodgers 88 - 77.8 = 10.2
Edinson Volquez, Padres 93.6 - 83.4 = 10.2
