Sean Doolittle’s High-Stakes Fight Against Pressure and Time
Sean Doolittle threw 10 pitches to Billy Hamilton on Saturday. Every one of them was a fastball, and all but one of them were in the upper third of the strike zone or higher. That’s what Doolittle does. No one in baseball throws a higher rate of fastballs than Doolittle’s 89.2%, and no one throws a higher rate of them in the upper third of the zone or higher than his 54.2%. He wears hitters out there, and that’s what he did to Hamilton. After a lengthy battle, the Braves’ new speedster didn’t have enough in the tank to get a piece of this last pitch.
That was a good outing for Doolittle. He retired all three hitters he faced, two of them on strikeouts. Even though Washington failed to rally in the top of the ninth, losing 5-4 to Atlanta, that kind of inning might have left a few Nationals fans feeling a bit more encouraged about their team’s overall outlook than they did before the game. That’s because recently, a dominant inning of work from Doolittle has no longer been the near-guarantee it used to be.
From 2017-18, Doolittle was incomprehensibly great. He threw 96.1 innings between Oakland and Washington and held a 2.24 ERA with a 2.27 FIP. He struck out 122 batters while walking 16. In terms of the game’s elite relievers, Doolittle was practically without equal. But this season, he hasn’t packed nearly the same punch. His ERA is 4.09, and his FIP is 4.23. His xFIP, which was a jaw-dropping 2.68 just last year, is now 5.05. He’s striking out two fewer batters per nine innings and issuing walks at his highest rate since 2015. After allowing just eight homers over the previous two seasons combined, he’s surrendered 10 this season. Read the rest of this entry »
