(Sports Network) - The Colorado Rockies take aim at their season-high fifth straight win this afternoon, as they try and complete a three-game sweep of the Milwaukee Brewers at Coors Field.

On Saturday, Brad Hawpe's grand slam was all Greg Reynolds needed to earn his first major league win, as Colorado rolled to a 7-2 win. Chris Iannetta and Ian Stewart added solo home runs for the Rockies, whose winning streak comes on the heels of an eight-game slide.

Reynolds (1-3) allowed two runs on four hits and two walks through six-plus innings. The bullpen threw three innings of scoreless ball to seal the win.

Dave Bush (2-6) was shelled for five runs on five hits and two walks through four innings in the loss. Russell Branyan and Jason Kendall plated Milwaukee's runs, as the club has dropped two in a row following a six-game win streak.

The Brewers have also lost six straight at Coors.

Hoping to complete the Rockies first three-game sweep of the Brewers since July of 2003 will be left-hander Jeff Francis, who is 2-5 with a 5.53 ERA. Francis, though, had one of his best outings of the season in his last start on Tuesday against the Los Angeles Dodgers, as he scattered four hits over seven scoreless innings to get the win.

Francis is 2-2 lifetime against the Brewers with an 8.71 ERA in four starts.

Milwaukee will counter with right-handed veteran Jeff Suppan, who is 3-4 this season with a 3.93 ERA. Suppan did not get a decision on Monday against Arizona, as he allowed three runs and seven hits in seven innings of his team's 4-3 victory.

Suppan, who has lost his last four starts on the road, has had success against the Rockies in his career, going 5-1 against them with a 3.58 ERA in eight starts.

Colorado won all three of its matchups at home against the Brewers last season on the way to taking four of six in the season series.
