Ryan Braun homered in the bottom of the eighth two give the Brewers a 3-2 lead which Trevor Hoffman closed out in the ninth for the win.
Dave Bush pitched another great game. Bush went seven solid innings giving up only two runs on four hits. He struck out four and walked none on the night.
Milton Bradley homered off of Bush in the fifth inning to get the scoring going for the Cubs. It was Bradley's third home run of the season.
The Cubs added another run in the sixth. Bobby Scales scored on an Alfonso Soriano sacrifice fly to center after Scales hit his first career triple.
Rookie Randy Wells filled in very nicely for the injured Carlos Zambrano. Wells threw five shutout innings and struck out five batters.
The Brewers began to rally in the bottom of the sixth when JJ Hardy hit a home run off of Cubs' reliever, Angel Guzman. The deep ball was Hardy's fifth of the year.
Guzman got through two innings giving up only the single run and it appeared the Cubs' bullpen would put the Brewers away for the night.
The Cubs had a chance to blow the game open when they loaded the bases in the top of the eighth with only one out. Carlos Villanueva was able to get Ryan Theriot to ground back to him to get a force play at home.
Mitch Stetter then came on to face Geovany Soto. Stetter was able to get Soto to ground out to first baseman Prince Fielder and the Brewers avoided any further damage.
Aaron Heilman came on in the eighth inning and promptly walked Corey Hard on four straight pitches.
That brought the Brewers' best clutch hitter, Ryan Braun, to the plate. On Heilman's second pitch, Braun sent a fly ball to deep into the right field bleachers and the Brewers took their first lead of the night, 3-2.
Trevor Hoffman entered the game in the ninth and struck out two batters to pick up his fifth save of the season.
The Cubs lost more than just the game. Aramis Ramirez left the game in the third inning with what turned out to be a separated shoulder. Ramirez may be the one bat the Cubs can't replace in their lineup.
The Brewers and their fans should be happy with a well-earned victory. However, they should avoid taking too much join from the game. It is only one win in a series in early May. There is a long way to go in the season.
The two teams will play the second game of the series Saturday night at Miller Park when Ryan Dempster takes the mound for the Cubs against the Brewers' ace, Yovani Gallardo.
