(Sports Network) - The National League Central-leading Milwaukee Brewers shoot for their sixth straight series win today, when they wrap up a three-game set with the division-rival Chicago Cubs at Wrigley Field. The Brewers lost the opener of this series on Friday, but rebounded with a 13-4 pounding of the Cubs yesterday afternoon. Ryan Braun hit a two-run homer and went 4-for-5 with four RBI to lead the way, as the Brewers extended their lead over Chicago in the NL Central to 7 1/2 games. Craig Counsell homered and Prince Fielder added three RBI for Milwaukee, which has won 13 of its last 16 games. Milwaukee starter Ben Sheets won his sixth straight decision, allowing four runs on six hits with one walk and a season- high 11 strikeouts in eight innings of work. Dave Bush gets the nod for the Brewers on Sunday and he is 6-6 with a 5.06 earned run average in 16 games (15 starts) this season. Bush has won three straight decisions and recorded the victory his last time out in a relief role. Bush pitched two shutout innings during a 6-3 triumph over Houston on June 27 at Miller Park. The right-hander owns a 1-4 record with a 4.15 ERA in seven career starts against the Cubs. He is 0-2, however, with a 7.50 earned run average in two outings versus Chicago this season. Chicago had its seven-game winning streak stopped with Saturday's loss. Mark DeRosa drove in two runs for the Cubs, while starting pitcher Sean Marshall was tagged for seven runs -- six earned -- on seven hits in just two innings for the loss. The Cubs will hand the ball to Jason Marquis this afternoon and he is 5-4 with a 3.46 ERA in 16 starts this season. Marquis, though, is 0-3 over his previous nine trips to the rubber and did not factor in the outcome his last time out on June 25 against Colorado. Marquis was reached for three runs in 5 2/3 innings of a 10-9 win over the Rockies. The veteran right-hander is 4-6 with a 4.23 ERA in 14 career games (12 starts) against Milwaukee. Marquis faced the Brewers on June 4 this season and did not post a decision, yielding two runs -- one earned -- in 5 1/3 frames of a 7-2 Chicago victory. Chicago is 6-5 against the Brewers this season, including a 2-3 record in the friendly confines of Wrigley Field.
