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.
"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."
"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.
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."
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 eight games between the teams this season, 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.
Corbin scrawled the number 45 in the dirt on the back of the mound in the bottom of the first, a tribute to late Los Angeles Angels pitcher Tyler Skaggs. He's been doing that since Skaggs died July 1 of a toxic mix of drugs and alcohol. "Obviously, we all miss him," Corbin said.
BACK IN THE DAY
Buehler and catcher Will Smith formed an all-Kentucky battery. Buehler is from Lexington and Smith is from Louisville, where he attended college. Buehler pitched at Vanderbilt. They played against each other in high school and college. "You could tell back then he was special," Smith said, recalling Buehler threw 95 mph in high school.
IN THE CROWD
Magic Johnson and Billie Jean King, part of the Dodgers' ownership group, shared a box with principal owner Mark Walter, Sandy Koufax and Tom Lasorda. ... Hall of Famer Dave Winfield, former Dodger Matt Kemp, former Dodgers manager Joe Torre and actor Jason Bateman attended.
Coming off the first relief appearance of his career, Washington RHP Stephen Strasburg will start Game 2 against Dodgers LHP Clayton Kershaw on Friday. Strasburg tossed three shutout innings Tuesday night in a dramatic wild-card victory over Milwaukee. He's under no limitations returning two days later. "My arm's felt great all year," Strasburg said. He would be available to return on normal rest for a potential Game 5 next Wednesday in Los Angeles. By starting Kershaw in Game 2, the Dodgers could possibly use him out of the bullpen if Game 5 is necessary.
