LOS ANGELES — The Dodgers overpowered the Nationals on the mound and at the plate, extending the dominance that led to a franchise-record 106 victories in the regular season right on into the playoffs.
Walker Buehler allowed one hit over six innings, Max Muncy drove in three runs and Los Angeles capitalized on mistakes to beat Washington, 6-0, in Game 1 of their National League division series on Thursday night.
“Oh, they’re good. They’re really good,” Nationals Manager Dave Martinez said. “That’s why they have been in the postseason so many years in a row.”
Buehler struck out eight, walked three and retired his final seven batters after earning the start over the veterans Clayton Kershaw and Hyun-Jin Ryu, whose 2.32 E.R.A. was lowest in the majors this season.
“Walker, time and time again, just knows how to temper, control his emotions and transfer that into the delivery, the execution of pitches,” Dodgers Manager Dave Roberts said.
The Dodgers’ 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 St. Louis 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.
“That first inning was the game,” Roberts said. “That really set the tone.”
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.
“Walked a lot of guys, chased a lot of bad pitches,” Martinez said. “When you’re walking guys and not hitting, it’s tough to win ballgames.”
Corbin gave up two runs — one earned — and three hits in six innings. The left-hander struck out nine and finished with five walks.
“It just didn’t seem like he had his command,” Muncy said. “We did a really good job of not chasing balls out of the zone.”
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.
“I wouldn’t change anything about the way I tried to make that play. Just one of those times you just miss it,” Kendrick said. “You never want to let your teammates down or do anything that could give the other team the advantage.”
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.
“Mechanically, was rushing a little bit. Was cutting my fastball,” Corbin said. “Later on, was able to get back to my sinker and everything else felt good after that.”
Muncy added a two-run single with two outs in the seventh, extending the lead to 4-0.
The Nationals loaded the bases in the fourth on three walks by Buehler. He escaped when Asdrubal Cabrera tapped the ball back to the mound and Buehler flipped to first to end the inning.
“From that first throw, he was on point,” Roberts said. “That’s a really good lineup over there and for him to go six, we needed that.”
Juan Soto, who had the key hit in the Nationals’ wild-card win over Milwaukee, singled in the second and Trea Turner doubled in the ninth off Joe Kelly for the Nationals’ only hits.
It was a quiet offensive night for each team’s M.V.P. 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 eight games between the teams this season, the third by the Dodgers.
Los Angeles won its eighth in a row dating to the regular season. Washington’s nine-game winning streak, including the wild-card victory, ended.
