They played the 3-seed St. Louis Cardinals, who clinched the National League Central on September 29, the final day of the regular season.

Muncy drove in two more runs with a bases loaded single off Fernando Rodney in the seventh and Gavin Lux hit a pinch-hit homer off Hunter Strickland in the eighth.

Joc Pederson also homered off Strickland to extend the lead, as the Dodgers held the Nationals to two hits in the 6–0 win.

[24] At 21 years and 314 days, Gavin Lux was the youngest player all-time to hit a pinch-hit home run in the playoffs.

He was also the youngest Dodger to hit a home run in a playoff game, with that previous record belonging to Cody Bellinger, who homered at the age of 22 years and 88 days during the 2017 NLDS against the Arizona Diamondbacks.

The Dodgers loaded the bases off Daniel Hudson in the ninth but failed to score and the Nationals evened up the series at one all with the 4–2 win.

Juan Soto hit a two-run homer off Ryu in the first inning to give the Nationals the early lead.

Kiké Hernández drove in two more later that inning with a pinch-hit double and Justin Turner followed that with a three-run home run off of Wander Suero.

Martin hit a two-run homer off Hunter Strickland in the ninth to give the Dodgers ten runs in the game.

In the third inning, Hill loaded the bases on two walks and a single before Anthony Rendon hit a sacrifice fly to tie the score.

The Dodgers jumped on Strasburg in the bottom of the first with a double by Joc Pederson followed by a two-run home run from Max Muncy, his third of the series.

Back-to-back home runs in the eighth by Rendon and Juan Soto off Clayton Kershaw tied the game.

Howie Kendrick hit a grand slam off of Joe Kelly in the top of the tenth inning to give the Nationals a 7–3 lead.

2019 NLDS (3–2): Washington Nationals beat Los Angeles Dodgers This was the fifth postseason meeting between the Braves and Cardinals.

The Braves quickly got to work against Mikolas, with Ronald Acuña Jr. and Ozzie Albies both drawing walks and Freddie Freeman singling to load the bases.

Tommy Edman would then double and move Fowler to third and Keuchel was relieved by Darren O'Day, who got Paul Goldschmidt to line out to shortstop Dansby Swanson.

One out later, Swanson singled in two runs on a ground ball to shortstop Paul DeJong that was deflected by Edman's glove.

Chris Martin came out the bullpen, but did not throw a pitch as he left with an oblique injury, and was replaced by Luke Jackson.

Martínez would end the rally though, getting Donaldson to ground out and striking out Markakis to seal the Game 1 victory for St. Louis.

Jack Flaherty, who was the Cardinals ace for the second half, got the ball for Game 2, and was opposed by right-hander Mike Foltynewicz.

Like Game 1, the Braves got to work quickly against Flaherty, with an Albies infield hit, a wild pitch and an RBI single from Donaldson.

St. Louis took an early 1–0 lead, as Marcell Ozuna had a second-inning double then scored following a ground out and sacrifice fly.

However, in the fifth inning, Hudson ran into trouble as Dansby Swanson doubled with one out and Adam Duvall reached on a fielding error by Matt Carpenter.

One out later, Albies hit a two-run home run to put the Braves ahead 4–3 and chased starter Dakota Hudson from the game.

The Cardinals would rally to tie the game in the eighth when Goldschmidt doubled with one out and scored on a Yadier Molina single that just got by the leaping Freddie Freeman.

The Cardinals would win it in the bottom of the tenth, when Kolten Wong doubled to lead off the inning, Goldschmidt was intentionally walked, Ozuna grounded into a forceplay and Molina, who tied it in the eighth inning, walked it off with a sacrifice fly that scored Wong and sent the Cardinals back to Atlanta for a Game 5.

Atlanta starting pitcher Mike Foltynewicz lasted only 1⁄3 of an inning, leaving after allowing three hits and three walks (one intentional); he was charged with seven runs (six earned).
