MILWAUKEE (AP) -- Houston manager Phil Garner isn't worrying about the standings until his Astros reach the .500 mark.

Lance Berkman had two home runs and four RBI, and Jason Hirsh pitched six-plus strong innings to lead the Houston Astros to a 10-4 victory over the Milwaukee Brewers on Saturday night.

Houston won its third straight game to move into second place in the NL Central, one-half game ahead of Cincinnati. The last time the Astros (70-71) were in second was May 6.

"We're one game closer to .500 and that's our goal," Garner said. "We want to get to .500. We got there [before] and had trouble pushing over. We've got to get over the hump."

Berkman agreed: "It's what we've said all along. We've got to get to .500 before we can even think about making a run at the postseason. We've been close a couple times but haven't been able to get over the hump. Maybe this is the time we can get over .500 and make up some ground on these guys we've been chasin'."

Adam Everett and Luke Scott also homered for Houston, sending Milwaukee to its third straight loss and 13th in 15 games.

"We didn't hit the ball against [Hirsh]," Milwaukee manager Ned Yost said. "We didn't do much against him. It was just one of those nights where we got beat."

Hirsh (3-3) gave up four hits while starting for Roger Clemens, who remains day-to-day after he left Monday's game with a strained right groin. Houston starters have allowed three runs or fewer in each of the last 11 games.

"My mentality going out there is a lot better," Hirsh said. "I'm just going out there throwing strikes and letting the ball work. It definitely makes it easier to go out and throw strikes. A lot less pressure. It's a lot more comfortable when you have a lead."

Berkman homered in the first to give Houston a 3-0 lead and added a solo shot, his 39th of the season, in the seventh. In his last three games, Berkman is 7-for-11 with eight RBI.

"The three-run home run by Berkman was large," Garner said. "That puts a damper on them right away. It puts the defense on their heels because they can't throw the ball over the plate. We take advantage of it by scoring a bunch of runs."

Milwaukee starter Tomo Ohka (4-5) allowed six earned runs, five walks and three hits in two-plus innings. It was the right-hander's shortest outing since he threw two innings with Montreal against Florida on Sept. 6, 2003.

Ohka, who threw 36 pitches in the first inning, has just one victory in his last nine starts and dropped to 1-4 in eight career starts against Houston.

"He struggled with his command from the get-go," Yost said.

Scott hit a two-run triple for a 6-0 lead in the third and Everett followed with a two-run homer, his fifth of the season, two batters later.

After Milwaukee's David Bell hit his eighth home run of the season in the third to make it 8-1, Scott connected on a solo shot in the fifth, his fifth of the season.

Bell had an RBI single in the seventh and Corey Hart hit his eighth homer, a two-run shot in the eighth, to close the scoring.

"It's tough when you look up and you're already down eight," Hart said. "But that was early. We still had a chance. But it definitely makes for a long night."
