MILWAUKEE -

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.
