Chris Tillman Ain’t Right
Joey Votto might have the most discerning eye in all of baseball, and this season he’s somehow made his own approach something even closer to perfect. Votto has swung at just 19% of pitches out of the strike zone, a rate which counts as especially low. At the same time, Votto has swung at 70% of pitches in the strike zone, a rate which counts as unusually high. When running discipline analysis, I like to compare those two rates. Votto has a swing-rate difference of 51 percentage points. It’s enormous. Joey Votto swings mostly at strikes.
Chris Tillman has started five games since coming off the disabled list, and he’s thrown 452 pitches. When he’s thrown a pitch out of the zone, he’s gotten a swing 24% of the time. When he’s thrown a pitch in the zone, he’s gotten a swing 75% of the time. Tillman, therefore, is running a swing-rate difference of 51 percentage points. Hitters who’ve faced Chris Tillman to this point in 2017 have, on average, been about as disciplined as Joey Votto.
