Estrada (7-4) threw 114 pitches and worked into the seventh inning Wednesday afternoon, a little more than 12 hours after Tuesday night’s game finally ended, and Gennett belted a second-inning grand slam off Stephen Strasburg to power the Brewers to a 9-2 win in the series finale at Miller Park.
Milwaukee (48-32) salvaged the final game of the series after dropping the first two, including a 4-2 loss in 16 innings Tuesday night/Wednesday morning.
The Nationals (41-36) also burned up most of their bullpen in the marathon and both teams made roster moves to bolster their bullpens prior to Wednesday’s game.
But Strasburg (6-6) wasn’t sharp and couldn’t get out of the fifth inning, matching a career high by allowing seven earned runs.
Washington scored first, getting a run on a Nate McLouth fielder’s choice in the second. But in the bottom of the inning, Gennett got the rout on its way.
Mark Reynolds led off the inning with a single to left and one out later went to third on a double by Elian Herrera. Martin Maldonado walked to load the bases and after Estrada struck out, Gennett took a fastball straight away to center field for his first career grand slam.
It was his fifth homer of the season.
The Nationals got one back in the top of the fourth on an RBI double by Ian Desmond, but Khris Davis made it a three-run game again quickly, leading off the bottom of the inning with a homer to left-center.
Davis took over the team lead with 14 home runs this season—11 of them since May 1.
Milwaukee delivered the knockout punch to Strasburg in the fifth, doing all of the damage with two outs.
Davis came up and took a big swing, but hit a little flare into short right-center field that brought home Gomez and Overbay and ended Strasburg’s afternoon.
It was only the second time Strasburg has allowed seven earned runs in a start, the first since July 12, 2013, against the Miami Marlins.
The Brewers capped the scoring off reliever Jordan Hill—making his major-league debut—in the sixth. Maldonado led off with a single and moved up to second on Estrada’s sacrifice bunt.
Gennett lined a single to left to score Maldonado and moved up to second on the throw. He then moved up to third on a ground out and scored on an infield single by Gomez.
Gennett drove in five runs on the day, becoming the first Brewers leadoff hitter with at least five RBI in a game since Marquis Grissom drove in five against the Houston Astros on Sept. 26, 1999. The only other leadoff hitters with five-RBI days in Brewer history are Fernando Vina, Jim Gantner and Paul Molitor (twice).
Estrada came up big when he had to for the Brewers, working 6.1 innings and allowing two runs on just two hits, walking four and fanning four.
Most importantly, for just the second time in 16 starts this season, he did not surrender a home run. Estrada, who has given up a Major League-leading 24 homers this season, hadn’t gotten through a start without surrendering a long ball since April 15 against the St. Louis Cardinals.
Brandon Kintzler—the only Brewers reliever other than Rule 5 draftee Wei-Chung Wang not to pitch on Tuesday—got the final two outs of the seventh, striking out one, and Alfredo Figaro—called up from Triple-A Nashville earlier in the day—worked two perfect innings to close it out.
The Brewers banged out 13 hits, with Gomez going 3-for-4 after being held hitless two straight games. Davis was 2-for-4 and Gennett and Jean Segura each went 2-for-5.
The Brewers open up a four-game set at home on Thursday, hosting the Colorado Rockies—whom they swept in Denver last weekend. Wily Peralta (8-5, 3.02 ERA) takes the ball for Milwaukee against left-hander Christian Friedrich (0-1, 6.00 ERA).
