Doolittle slammed the door on Baltimore on Thursday, firing a perfect ninth innings to secure his 20th save of the season in a 4-2 victory.

EDGE Analysis

Doolittle has locked down a save in both his opportunities since Washington acquired Kelvin Herrera and it looks like he's the clear closer moving forward. The 31-year-old lefty has a 1.65 ERA and 43:3 K:BB in 32.2 innings. He's also converted 20-of-21 save opportunities, with the lone blown attempt coming back on May 19.

Doolittle allowed one run over one inning in Tuesday's win over the Orioles to collect his 19th save of the season.

EDGE Analysis

Doolittle allowed a solo homer to Joey Rickard but was able to induce three fly outs to secure the win for the Nationals on Tuesday.

EDGE Analysis

Doolittle has put up outstanding numbers through the first few months of the 2018 campaign, so it's no surprise that the Nationals will stick with him as their closer. He's posted a 1.52 ERA and 0.57 WHIP with an outstanding 41:3 K:BB over 29.2 innings this season.

Doolittle struck out one in a perfect ninth inning Wednesday to record his 17th save of the season in a 5-4 win over the Yankees.

EDGE Analysis

He's blown only one save all year so far, and Doolittle's numbers are among the league's elite as he's posted a 1.52 ERA and 41:3 K:BB through 29.2 innings. If he can stay healthy, the left-hander should easily top last year's career-high 24 saves, and he could get there by the All-Star break.

Doolittle allowed no runs on one hit while striking out one across 1.1 innings as he slammed the door for the save Saturday against the Giants.

EDGE Analysis

Doolittle allowed two hits in a scoreless ninth inning Wednesday to pick up his 13th save of the season in a 2-0 win over the Orioles.

EDGE Analysis

The left-hander gave up as many hits in his first nine pitches as Max Scherzer did in his eight innings, but Doolittle quickly settled down after picking off Craig Gentry trying to steal third base for his first out. The Nats closer now has a 1.78 ERA and minuscule 0.63 WHIP through 24 appearances and 25.1 innings.

Doolittle struck out two in 1.2 perfect innings Friday to record his 10th save of the season in a 9-5 win over the Marlins.

EDGE Analysis

Brandon Kintzler put two runners on base in the eighth inning, creating the save situation for Doolittle, but the left-hander quickly retired Justin Bour and Starlin Castro to neutralize the threat and then breezed through the ninth. Doolittle now has a 2.01 ERA and eye-popping 35:3 K:BB through 22.1 innings on the season.

Doolittle struck out the side in a perfect ninth inning Tuesday to record his second win of the season in a 2-1 victory of the Padres.

EDGE Analysis

Michael Taylor's walkoff double in the bottom half of the frame gave Doolittle the win, as the left-hander bounced back from his first blown save of the season in his last appearance Saturday. The Nats closer now sports a dominant 2.18 ERA, 0.63 WHIP and 33:3 K:BB through 20.2 innings this year.

Doolittle allowed one hit and struck out one over a scoreless ninth inning Sunday to record his ninth save of the season in a win over the Diamondbacks.

EDGE Analysis

Nats manager Dave Martinez has been keeping a close eye on Doolittle's workload, and it's been paying off, as the left-hander's reeled off 10 straight scoreless appearances with a 12:0 K:BB in 10.2 innings over that stretch while picking up seven saves and a win. He'll likely continue to cede the occasional save to Ryan Madson, but if it keeps Doolittle healthy -- last year's 51.1 innings was his highest total since 2014 -- those with fantasy shares in the closer will be more than happy with the tradeoff.

Doolittle got the save against Arizona on Thursday, giving up one hit and striking out one with no walks to close out the Nationals' 2-1 extra-inning victory.
