Josh Wilson hit a tiebreaking home run in the top of the 11th to lift the Milwaukee Brewers to a 6-5 victory Sunday at Sun Life Stadium.

Wilson's homer off Mike Dunn (4-3) was only the ninth of his five-year major league career, but it was his second since the Brewers claimed him off waivers from Arizona on May 25.

The victory gives the Brewers three consecutive road wins for the first time since last September while sending the Florida Marlins to their fourth consecutive one-run loss.

Brett Hayes' first career grand slam dug the Marlins out of a five-run hole, and Florida seemed poised to win it when it loaded the bases with one out in the ninth, but righthander Tim Dillard (1-0) came on and got out of the jam by getting a grounder from Gaby Sanchez and a flyout from Mike Stanton.

The Marlins also had runners at first and second with one out in the 11th, but John Axford induced a popup from Logan Morrison and a grounder from Sanchez for his 16th save in 18 opportunities.

Rickie Weeks helped the Brewers build a 5-0 lead with a two-run home run in the third and an RBI single in the fourth. The homer was the 100th of Weeks' career and his 11th of the season.

The Brewers have at least one home run in 10 of their past 11 games. They have won 20 of 27 and are seven games over .500 for the first time this season.

Florida has lost 11 of 15 at home and six of seven overall.

Marlins shortstop Hanley Ramirez missed his sixth consecutive game because of inflammation in his lower back; he is expected to go to the disabled list Monday.
