Milwaukee, WI (Sports Network) - Casey McGehee hit a three-run homer and Rickie Weeks clubbed a two-run shot, as the Milwaukee Brewers completed a three-game sweep of the Washington Nationals with an 8-3 victory at Miller Park.
Jonathan Lucroy went 2-for-4 with an RBI and run scored for the Brewers, who have won four straight.
Dave Bush (5-8) earned the win for allowing three runs -- two earned -- on six hits with seven strikeouts and did not issue a walk over six innings.
"I like to work quickly and throw a lot of strikes and kind of force the tempo," Bush said. "Any win is a good one no matter who it's against."
Adam Dunn and Nyjer Morgan had two hits and an RBI apiece for Washington, which has lost seven of nine.
Ross Detwiler (0-1) was tagged with the loss after working only 3 2/3 innings and giving up five unearned runs on three hits with as many walks and struck out four. The left-hander was a replacement for starter Luis Atilano, who was placed on the 15-day disabled list with bone chips in his pitching elbow.
"We did not have a good day defensively today," Nationals manager Jim Riggleman said. "We certainly didn't get it done today, but Detwiler has to pitch around them (errors). I thought he did a good job and minimized the damage. We're just having growing pains."
Milwaukee put two runs up in the first to grab the early advantage. With the bases loaded and two outs, Lucroy punched a run-scoring single through the right side and Detwiler's wild pitch allowed another run to score for a 2-0 game.
The Brewers then tacked on three more in the fourth. Lucroy led off with a single and stole second. Bush then hit a grounder to shortstop, but Ian Desmond's throwing error allowed Lucroy to score with Bush taking second. Weeks followed by hammering a 1-1 offering into the left-field seats to put Milwaukee ahead 5-0.
Washington got on the board in the sixth on a sacrifice fly from Josh Willingham and an RBI single by Dunn. Morgan's run-scoring base hit in the seventh drew the Nationals to within 5-3.
However, the Brewers responded with a three-run home half. Alcides Escobar tripled leading off and Prince Fielder was intentionally walked two batters later. McGehee then stepped up and cleared the bases with a three-run blast to center.
Kameron Loe worked a scoreless eighth and Trevor Hoffman got the final three outs in the ninth to close out the win.
