Scherzer (7-1) gave up four hits and one run, and he retired the final 15 he faced after David Peralta homered to lead off the third inning. Scherzer struck out 11 and did not walk a batter as the Nationals won for the 11th time in 13 games.

Peralta had two of Arizona's five hits, but the Diamondbacks got only one runner on base after Peralta's homer. Sean Doolittle pitched around a one-out single in the ninth inning by Paul Goldschmidt for his eighth save.

The Diamondbacks have lost three in a row and six of nine and are in danger of losing their first series of the season after dropping the first two games of this four-game set. They are 10-0-2 in series.

Arizona right-hander Matt Koch (2-1) gave up seven hits and three runs in eight innings, the longest start of his career. Koch has faced Clayton Kershaw, Justin Verlander and Scherzer is his last three starts. Arizona won the first two.

Turner hit the eighth pitch of the game for his seventh career leadoff homer to give the Nationals a 1-0 lead.

Peralta singled and Jarrod Dyson beat out a bunt single, and the runners took second and third on a throwing error by Scherzer with no outs in the first inning, but Scherzer got out of it with two strikeouts and a popout.

Ketel Marte tripled with one out in the second before Scherzer struck out the final two batters of the inning.

Peralta tied it at 1 with his leadoff homer in the third inning.

Scherzer gave himself a 2-1 lead with a two-out, ground-rule double in the fourth inning after Andrew Stevenson was hit by a pitch and Pedro Severino singled.

Arizona announced right-hander Troy Scribner will be purchased from Triple-A Reno to oppose Washington right-hander Stephen Strasburg on Saturday. Scribner was 2-1 with a 5.68 ERA in five starts at Reno. He made 10 appearances with the Angels last season.
