(My Sportsbook) - The Milwaukee Brewers have been unbeatable over the last 10 days, except for games in which Manny Parra has pitched. The struggling hurler hopes to end his struggles when he takes the mound for the red-hot Brewers in tonight's clash with the Arizona Diamondbacks from Miller Park.

Milwaukee enters this evening's tilt having won eight of their last nine games, with the team's lone blemish over that span -- a 3-2 setback at Houston last Sunday -- coming in Parra's last start. Parra was also on the hill for the Brewers' second most-recent loss, an 11-4 defeat at Philadelphia on April 21 in which he was reached for five runs and walked three in four innings of work.

Parra is 0-4 with a 6.52 earned run average through his first four 2009 starts and hasn't gone past five innings in three of those outings. In addition, he has issued 12 walks over a combined 19 1/3 frames.

The left-hander pitched a little better in Sunday's loss to the Astros, as two of the three runs Parra allowed were unearned in his five-inning start. However, he did walk three batters and threw 97 pitches before exiting.

Parra will be attempting to get back on track against a team he has excelled against so far during his brief big-league career. The 26-year-old faced the Diamondbacks twice as a rookie last season and yielded just one run in 13 innings over those starts, earning a win in one and a no decision in the other.

The Brewers extended their current winning run to four games with a 4-1 decision over Arizona in last night's opener of this four-game series. Milwaukee scored all four of its runs against the Diamondbacks' bullpen in the seventh inning, with Prince Fielder's bases-loaded walk forcing in the go- ahead score.

Arizona starter Max Scherzer held the Brew Crew scoreless over the first six innings and departed with a 1-0 lead, but the combo of Tom Gordon, Juan Gutierrez and Scott Schoeneweis failed to protect that narrow margin. Gordon (0-1) was charged with all four runs allowed and recorded just one out before being taken out.

Mike Cameron finished 3-for-4 and lengthened Milwaukee's advantage to 4-1 with a two-run double off Schoeneweis in the seventh.

Mark DeFelice (2-0) picked up the victory for the Brewers, who have now won five in a row at home, after getting the final two outs of the top of the seventh, while Trevor Hoffman earned his 556th career save by throwing a scoreless ninth.

Jeff Suppan worked the first 6 1/3 innings for Milwaukee and gave up just one run on six hits without a walk.

Arizona, which had won three of its last four coming in, turns to Jon Garland tonight in hopes of evening this series. The veteran righty had his longest start of the season Sunday against San Francisco, a 7 1/3-inning stint in which he allowed four runs on 10 hits and did not receive a decision in his team's 5-4 win over the Giants.

Garland was quite sharp in his previous outing, a 6-3 triumph over Colorado on April 20. In that game, the offseason addition limited the Rockies to two runs -- one earned -- and struck out five batters.

Having pitched exclusively in the American League before this season, Garland started against the Brewers only once during his first nine years in the majors. That came with the Chicago White Sox in 2000, with the 29-year-old tossing seven innings of two-run ball to register a win.

Milwaukee went 5-2 against Arizona in 2008, with a three-game sweep of the D'Backs at home from June 2-4. The Brewers are 11-4 in the series since the start of the 2007 campaign and 7-1 as the host over that time.
