LOS ANGELES — Walker Buehler allowed one hit over six spotless innings, Max Muncy drove in three runs and the Dodgers capitalized on mistakes to beat the Nationals 6-0 in Game 1 of their NL Division Series on Thursday night.

Buehler struck out eight, walked three and retired the final seven batters he faced after earning the start over veterans Clayton Kershaw and Hyun-Jin Ryu, whose 2.32 ERA was lowest in the majors this season.

“[Buehler] set the tone for us,” Muncy said. “He was pounding the zone.”

Dodgers rookie Gavin Lux and Joc Pederson slugged pinch-hit solo homers in the eighth.

Nationals first baseman Howie Kendrick had two grounders roll under his glove, the second leading to the Dodgers’ second run in the fifth.

Washington’s Patrick Corbin stumbled through a rocky first inning. He issued four walks, joining Art Reinhart of the Cardinals as the only pitchers to walk that many in the first inning they ever pitched in the postseason. Reinhart walked four — including Babe Ruth and Lou Gehrig — in the fifth inning of Game 4 of the 1926 World Series against the Yankees.

Corbin walked three in a row with two outs in the 31-pitch inning. Yan Gomes was charged with a passed ball, too, and Muncy drew a free pass with the bases loaded to put the Dodgers in front.

“We didn’t play very well today,” Nationals manager Dave Martinez said.

Corbin gave up two runs (one earned) and three hits in six innings. The left-hander struck out nine and finished with five walks.

Cody Bellinger walked with two outs and scored on an error by Kendrick in the fifth that made it 2-0. Third baseman Anthony Rendon made a diving stop on Chris Taylor’s single down the line, but his throw to first wasn’t in time and Bellinger went to third.

Muncy’s grounder rolled through Kendrick’s legs for an error, scoring Bellinger, and Taylor got thrown out at the plate to end the inning.

In the fourth, Muncy singled leading off. Corey Seager followed with a hit that got past a diving Kendrick at first and rolled into right, sending Muncy to third. But then Corbin settled down and retired the next three batters to end the inning.

The Nationals loaded the bases in the fourth on three walks by Buehler. He escaped when Asdrúbal Cabrera tapped the ball back to the mound and Buehler flipped to first to end the inning.

Juan Soto, who had the key hit in the wild-card win over Milwaukee, singled in the second and Trea Turner singled in the ninth off Joe Kelly for the Nationals’ only hits.

It was a quiet offensive night for each team’s MVP contender. Rendon, who hit .319 in the regular season, went 0 for 2 with two strikeouts and a walk. Bellinger, a .305 hitter, struck out twice and walked twice.

It was the fourth shutout in games between the teams this season, and the third by the Dodgers.
