Over the past few months, I have become obsessed with Andrew Kittredge. This obsession has prompted articles like this one, as well as tweets like this and this. After Tuesday night, when he threw a near immaculate inning en route to a two inning save against the Phillies, I felt the need to talk about him again, because I have noticed something different.
In Kittredge’s Tuesday night outing, he threw a total of 26 pitches. Of those 26 pitches, he threw 5 four-seam fastballs; just a shade below 20 percent. Pointing out pitch usage in a one game sample is tricky, but this is outside the norm for Kittredge, who has been heavily sinker and slider all season.
