MILWAUKEE (AP) -- Scooter Gennett had a grand slam and five RBIs, Khris Davis added a solo shot and the Milwaukee Brewers roughed up ace Stephen Strasburg in a 9-2 victory Wednesday over the Washington Nationals.
Homer-prone starter Marco Estrada (7-4) allowed just two hits -- and no homers --and pitched effectively into the seventh for the Brewers, who bounced back nicely a day after falling 4-2 in 16 innings to Washington.
Davis finished with three RBIs in a game in which nearly everything went right for Milwaukee. Carlos Gomez even drove home a run in the sixth on what looked like a swinging bunt that rolled slowly up the third-base line and stayed fair.
Strasburg (6-6) was tagged for eight hits and seven runs in 4 2/3 innings.
It matched a career-worst outing for Strasburg, who also allowed seven earned runs in a two-inning start on July 12, 2013, in an 8-3 loss to Miami.
The Brewers started pouncing on Strasburg in the second, when lefty-swinging Gennett turned on a 2-1 fastball for his first career grand slam and fifth homer of the season that landed on the concourse above right-center field.
Davis opened the bottom of the fourth with a no doubt-about-it shot above the "Goodwill" sign in left-center for his team-high 14th homer to make it 5-2. Gomez, who finished 3 for 4, could only smile at first after his slow roller in the sixth allowed Gennett to score from third for a seven-run lead.
About the only thing left in Miller Park by then to make it official was for the 39,000 fans to start singing and dancing to "Roll Out the Barrel" during the seventh-inning stretch.
Gomez also tripled to the warning track in the fifth on a hard-hit ball that took a tricky bounce off the wall for center fielder Denard Span. Strasburg departed three batters later after giving up a two-run single to Davis.
The Brewers' bats broke out after scoring just two runs in 25 innings in the first two games of a series between NL division leaders. Milwaukee had 13 hits, even with Ryan Braun, Aramis Ramirez and Jonathan Lucroy all getting a day off.
Estrada walked four and struck out four over 6 1-3 innings in a start that may secured in his spot in the starting rotation. Estrada, who has allowed a major league-worst 24 homers, didn't give up a homer for just the second time this season, the only other outing coming in a 6-1 loss to St. Louis on April 15.
This time, the 30-year-old right-hander walked back to the dugout after getting lifted from the game to a standing ovation.
NOTES: Gomez slid through second base on 2B Kevin Frandsen's relay on double play to end the eighth inning, and benches cleared after SS Ian Desmond and Gomez exchanged words after the play. No punches were thrown and the teams returned to their dugouts. ... Nationals OF Bryce Harper (left thumb) has joined Class AA Harrisburg for the next phase of his rehab stint for a left thumb injury. ... Manager Matt Williams said C Wilson Ramos (right hamstring) could rejoin the team in time for the start of Thursday's four game series in Chicago against the Cubs. ... Doug Fister (6-5) will start the opener of the Cubs series for Washington. Milwaukee opens a four-game set on Thursday at Miller Park with Wily Peralta (8-5) taking the hill.
