Zach Britton on Sinkers, WPA, and the Cy Young
In October 2011, a Q&A titled Zach Britton, Oriole in Progress was published in these pages. Britton had just completed a rookie season in which he went 11-11, with a 4.61 ERA, in 28 starts. He’d thrown his signature pitch 53% of the time.
Fast forward to today. Britton is still in Baltimore, but much has changed. He became a reliever in 2014, and the results have been nothing short of spectacular. Since moving to the bullpen, the 28-year-old southpaw has appeared in 199 games and fashioned a 1.42 ERA. Relying more heavily on his power sinker — he now throws it over 90% of the time — he has the highest ground-ball rate in the game (80.8% this year). He also misses bats. Britton strikes out better than a batter per inning.
This season he’s been next to un-hittable. In 61.1 innings, Britton has allowed just 34 hits. He’s recorded a microscopic 0.59 ERA and has 45 saves in as many chances. As August Fagerstrom wrote last month — many have echoed his opinion since that time — Britton is very much in the mix for this year’s American League Cy Young award.

Britton on his pitch mix and changing roles: “There were a lot more four-seamers back [in 2011]. As a starter, you throw more pitches and mix in different things. It was probably a negative for me that I wasn’t learning how to command the sinker as much as I am now. That was really the big focus when I went to the bullpen — the command of my sinker. The results have been really good once I got that focus.
