Some might have rolled their eyes when Brewers manager Ron Roenicke put Rickie Weeks in the leadoff spot for the first time in more than a year.

Some might have questioned why he didn't pull Weeks for a pinch hitter in the eighth inning against a right-handed reliever when the Brewers were down by a run.

No one's second-guessing now.

The second baseman continued to show signs that he is emerging from his extended slump with a two-run homer that was the difference Wednesday night in the Brewers' 3-1 victory against the Houston Astros at Minute Maid Park.

Until the moment that Weeks turned on a high slider from Hector Ambriz, the Brewers' long-slumbering offense had nothing going besides four singles off Astros left-handed starter Erik Bedard. With a run of right-handed hitters that Roenicke had placed in the lineup against Bedard coming up, Astros manager Bo Porter went to the pen.

It was the Brewers' gain as Roenicke resisted the temptation to pitch-hit Scooter Gennett, Caleb Gindl or Juan Francisco.

"A good ball game to win," Roenicke said. "It was a great at-bat for Rickie. It was a big hit and we've been needing big hits."

Brewers starter Kyle Lohse, who never seems to get run support, gave up just one run in six innings. John Axford was the pitcher of record, while Francisco Rodriguez earned the 299th save of his career.

Aramis Ramirez also broke his slump with a ninth inning home run, one of just two extra-base hits for the Brewers in the game.

But it was the first that gained the attention.

Weeks, who has been subject to a platoon with Gennett since the rookie was called up more than two weeks ago, was placed into the leadoff spot when Norichika Aoki went on paternity leave. Roenicke thought about leading off Logan Schafer but decided against it with Bedard on the mound.

Roenicke said it was difficult to tell whether the Gennett call-up has lit a fire under Weeks or if he is simply coming around like he typically does after a slow start.
