Bit by bit Milwaukee's offense is starting to take shape, which is usually the case with a series against the Houston Astros.

The Brewers look to move back over .500 for the first time in two weeks and win their 12th in a row over the Astros in Wednesday's finale at Miller Park.

After beating Houston 6-5 in Monday's opener, Milwaukee (9-9) hit a season-high four homers in Tuesday's 9-6 win. Corey Hart, Travis Ishikawa, Carlos Gomez and Rickie Weeks all went deep for the Brewers, who have averaged 6.5 runs in winning the last 11 meetings in the series since a 5-0 loss at Minute Maid Park on May 1.

This is Milwaukee's longest active winning streak over an opponent, and Houston's longest skid against one team.

Hart has been instrumental to this run, batting .405 with three home runs and seven RBIs in his last nine games against the Astros (6-12). He is 3 for 6 with four runs in the first two games of this series after going 5 of 28 (.179) in his previous eight contests.

Weeks appeared to break out of his slump Tuesday with a three-run homer after coming in batting .182 with two home runs and three RBIs.

"It was only a matter of time for our offense to kind of click in,'' said Randy Wolf, Tuesday's winning pitcher.

Weeks could be poised for another big game. Milwaukee's leadoff hitter is 4 for 5 with a homer and two doubles lifetime against scheduled starter J.A. Happ (1-1, 4.00 ERA), while Hart is batting .462 in 13 at-bats, also with a homer and two doubles.

Happ has also been part of Houston's struggles against the Brewers, going 0-2 with an 8.78 ERA in his last three starts in the series, yielding at least five runs in each outing.

Milwaukee's scheduled starter Shaun Marcum (1-1, 3.79) has one victory during the winning streak over the Astros, and went 2-0 with a 1.80 ERA in three starts against them last year. He struck out 22 and surrendered 11 hits over 20 innings.

Marcum gave up three runs and eight hits in six innings of Friday's 4-3 loss to Colorado, but didn't get a decision. The right-hander, who battled shoulder problems during spring training, has thrown 105 pitches in each of his last two outings and is the only pitcher on Milwaukee's staff to have notched a quality start in each of his outings.

Like Marcum, Happ is the only pitcher in Houston's rotation with a quality start in each of his outings.

Against the Los Angeles Dodgers on Friday, Happ allowed eight hits and four walks over six innings, but limited the damage to three runs. The left-hander didn't get much help from his offense, though, and was saddled with a 3-1 loss.

The Astros have lost 11 of 14 and another defeat will allow the Brewers to move back over .500 for the first time since April 12, when they were 4-3.

Despite Houston's woes, Jose Altuve is off to an encouraging start.

The second baseman hit his first homer Tuesday and also singled for his ninth multihit game. He is batting .344 with seven RBIs and a .403 on-base percentage after hitting .276 with two homers and 12 RBIs in 57 games last season as a rookie.
