Prince Fielder drove in four runs and Zack Greinke threw seven solid innings and hit a home run Wednesday to lead the Milwaukee Brewers to a 6-4 win over the Washington Nationals. It's the Brewers' ninth consecutive home win and their sixth straight victory overall.

Fielder opened the scoring with a two-run double in the first, added a sacrifice fly in the third and an RBI single in the seventh to take over the National League lead with 41 RBIs.

Greinke (3-1) allowed three runs on five hits with a season-high 10 strikeouts to win his third consecutive decision. His only mistake was on three-run home run in the fourth by Michael Morse, who hit a grand slam a night earlier.

Morse's fifth home run of the season tied it at 3-3, but Greinke broke the tie with a solo home run in the fifth, his second home run in 32 career at-bats.

Jason Marquis (5-2) took the loss, allowing four runs on five hits over six innings. He walked four.

Kameron Loe retired all four batters he faced for his second career save and his first of the season.

The Brewers swept the three-game series and improved their NL-best home record to 19-6.
