Just 24 hours after Miguel Tejada, Lance Berkman and Carlos Lee hit consecutive home runs in Friday's win, Brandon Backe and Michael Bourn hit back-to-back homers to lift the Astros to a 6-2 victory over the Brewers on Saturday night at Minute Maid Park.

Backe held Milwaukee to two runs in 5 2/3 innings, while the Houston offense stayed on a roll with 12 hits. In their last four games, the Astros have scored 26 runs and hit .314 (44-for-140).

"We're just continuing to do good stuff," Tejada said. "The good thing about this team right now, it's not one guy, it's everybody's hitting. That makes us a better team."

Tejada extended his hitting streak to eight consecutive games with a single and a double. The Astros shortstop has hit safely in 25 of his 31 games this season, including a .403 (27-for-67) batting average with 15 RBIs in his last 16 games. Berkman also contributed two singles as the Astros won their fifth consecutive home game.

"[Tejada] and Berkman have been the two really main [guys] really since the start of the season," Astros manager Cecil Cooper said. "Any time you get a couple of guys going, you hope the other guys chip in. Kazuo [Matsui, 2-for-2 with two walks, two runs scored and a stolen base] has been a nice spark since he came back from the DL.

"Hunter [Pence is] starting to swing it better and Carlos is a big key for us. We're getting contributions throughout. Michael did a good job tonight -- his home run was a big hit for us, gave us a little breathing room."

Backe sent a 2-2 curveball from Brewers starter Manny Parra (1-2) into the Crawford Boxes in left to give Houston a 2-1 lead in the fifth.

"It wasn't a good curveball," Parra said. "At the same time, credit to him for even hitting the pitch."

The Astros were just getting started.

Bourn followed and snapped an 0-for-9 string with his third homer of the season.

"I didn't want him on base, so I went right after him," Parra said. "I wasn't thinking, 'long ball,' at all there. I was behind in the count and wanted him to put the ball in play."

Consecutive hits by Matsui, Tejada and Berkman made it 4-1 Houston. A wild pitch scored Tejada and a walk to Lee loaded the bases and sent Parra to the showers.

Pence greeted Dave Bush with a single, scoring Berkman to make it 6-1 before the Brewers finally recorded an out in the inning.

The Astros tied the game at 1 in the third when Matsui scored from third on a Berkman ground ball.

Rickie Weeks led off the game with his fourth homer of the season. The Brewers second baseman rocketed an 0-2 pitch from Backe off the coal tender of the train that runs along the top of the left-field wall.

"It was a bad breaking ball to Weeks, but I still didn't think it was a ball where he could have -- first at-bat of the game -- could have driven that far," Backe said. "But he did a good job getting the barrel on the ball, like some of us do, and hitting it out of the ballpark."

After the Astros hung a five-spot on the scoreboard in the fifth, the last thing they needed was putting Brewers on base, but that's what Backe did with three walks in the sixth.

"I think he had to sit for a while. That's probably the main reason he did kind of lose command in the sixth inning," Cooper said. "He hit twice in one inning, so I'm sure that took a little bit out of him. I thought he threw the ball well for the most part, used his changeup a little bit more than he has all season. I thought it was effective for him."

Cooper won't complain about long innings by his offense if the results are crooked numbers on the board. Backe agreed he can't allow long innings to get him off his game in the future.

"I'm tired of all these walks I'm giving up and getting myself in trouble and ultimately not going as far as I want to go," he said.

Fortunately, Oscar Villarreal, Wesley Wright and Jose Valverde picked Backe up with 3 1/3 scoreless innings of relief.

"Oscar has been throwing much, much better, made some adjustments and he's been much better down in the strike zone. His slider has been really good," Cooper said. "I have to give kudos to the bullpen for the most part the last two nights. They've done well."

So has the offense.

"Hitting is contagious," Pence said. "Once one guy goes, starts giving you more at-bats, you start coming up to bat quicker, and you start getting the vibe and things start going. Baseball's somewhat of a swagger and you can't explain it, but we've got a good lineup and we're going to hit."
