Ben Sheets got within one out of pitching his third complete game of the season, and Prince Fielder and Russell Branyan homered to lead the Milwaukee Brewers past the Houston Astros 4-1 on Saturday night.

Sheets left after walking Lance Berkman in the ninth inning, but Salomon Torres came on to get Carlos Lee to fly out for his fifth save. Sheets (6-1) gave up seven hits while striking out five to win for just the second time this month.

Sheets had been 1-1 with three no decisions in his last five starts, mostly because of poor run support. His only win in that stretch came at Pittsburgh on May 21, when he gave up one run in a complete game.

The right-hander has allowed just four earned runs in his last three starts covering 23 2/3 innings.

The victory was the sixth in eight games for the Brewers, who still trail the front-running Chicago Cubs by seven games in the NL Central.

The Astros have lost four in a row, their longest losing streak of the season.

The Brewers fell behind 1-0 after Darin Erstad's run-scoring single in the third, but went ahead in the fifth. Rickie Weeks led off with a double to shallow left and scored on a base hit from Ryan Braun, and Fielder hit a 2-2 pitch from Brian Moehler over the right-field wall for his eighth homer of the season.

Branyan made it 4-1 in the sixth when he hit his second homer of the year over the right field wall off Astros reliever Oscar Villarreal.

Moehler (2-2) wound up allowing six hits in five innings, walking one and striking out six, but didn't much help from Houston baserunners.

Brewers catcher Jason Kendall foiled three of four steal attempts.
