Milwaukee, WI -- (Sports Network) - Geoff Blum's sixth-inning three-run home run made the difference, as the Houston Astros beat Milwaukee, 5-2, in the second of three games with the Brewers.

Brian Moehler (9-4) took the win after limiting Milwaukee to two runs -- one earned -- despite giving up nine hits in 5 1/3 innings. He also walked one and struck out four.

Michael Bourn finished with a triple and two runs batted in, while Darin Erstad and Humberto Quintero each collected two hits for Houston, which has won two of three.

Ben Sheets (11-7) continued his struggles after giving up all five runs on five hits in six innings. He walked just one and struck out seven, but lost his second consecutive start, and has now dropped four of his past five.

"It seems like I didn't make many mistakes. But the ones I did make, they hit hard," Sheets said. "I'm not pitching great, but I'm not pitching as bad as it's made out to be."

Jason Kendall had three hits, while Mike Cameron and J.J. Hardy each drove in a run for the Brewers, who have lost four of six.

With the score knotted at two runs apiece headed into the sixth inning, Erstad got the Astros going with a leadoff single. After Erstad stole second, Bourn was hit with a pitch.

Ty Wigginton flied out and Lance Berkman followed with a strikeout, but Blum took advantage of the situation by blasting a three-run shot to right-center field to give Houston a 5-2 lead.

"I was looking off-speed," Blum said. "I think it was a sinker or changeup. He just happened to leave it out over the plate, and I got a hold of it."

Kendall hit a one-out single in the sixth for Milwaukee, which forced Moehler out and brought in Chris Sampson, who got the final two outs of the inning. Geoff Geary worked a perfect seventh frame, LaTroy Hawkins was perfect in the eighth, and Jose Valverde notched his 32nd save of the season with a flawless ninth.

The Brewers took a first-inning lead. Ray Durham led off with a single and scored when Hardy followed with a double -- though Hardy was thrown out trying to get to third.

Milwaukee added another run in the second after Craig Counsell reached base when Berkman couldn't cleanly field his bunt. Cameron then doubled home Counsell for a 2-0 Brewers lead.

But Houston tied the game in the third. With one out, Quintero singled, though Moehler struck out. Erstad singled to put two runners on base, and Bourn sent them both home with his triple to right.

Game Notes:

Wigginton's 15-game hitting streak came to an end after an 0-for-4 night...Valverde's save was the 130th of his career, which broke a tie with Antonio Alfonseca and Kazuhiro Sasaki for 81st all-time. It also broke a tie with Alfonseca for fourth-most all-time by a Dominican-born player.
