(Sports Network) - The Milwaukee Brewers shoot for a three-game sweep of the Pittsburgh Pirates this afternoon at Miller Park.

The Brewers have won two straight and four of five games, including Saturday's 2-1 victory over the Bucos. Prince Fielder's RBI single in the bottom of the ninth lifted the Brewers to victory, while Eric Gagne got the win for tossing a scoreless top of the ninth. Gagne came off the disabled list on June 29.

Milwaukee starter Dave Bush allowed one run on four hits in eight innings, while striking out seven and walking none in the no-decision.

Pirates starter Paul Maholm did not factor in the outcome and also surrendered one run on four hits, struck out six and walked one through eight innings of work. Reliever Tyler Yates suffered the loss in the ninth inning.

Pittsburgh has lost two straight and four of six games.

Jeff Suppan will take the hill for the Brewers on Sunday, and he is 5-6 with a 4.30 ERA. Suppan last pitched on Tuesday at Arizona, hurling five innings for the win. He gave up five runs and nine hits to end a three-game winless streak (0-2).

Suppan, a right-hander, is 10-3 with a 3.95 ERA in 18 career starts against the Pirates.

Countering for Pittsburgh will be Zach Duke, who is 4-5 with a 3.88 earned run average in 2008. Duke is 0-2 in eight road starts this season and did not factor in the outcome of a 6-5 victory at Cincinnati on Tuesday.

Duke allowed just one run and six hits in five innings.

The lefty is 3-3 with a 4.36 ERA in nine career starts against Milwaukee.

Milwaukee took two of three from the Pirates earlier in the season after taking 10 of the 16 in the season-series a year ago.
