Matt Treanor achieved a career high in RBIs with one swing Thursday, hitting a three-run homer to help the Florida Marlins complete a three-game sweep by beating Milwaukee 7-2.

Jorge Cantu also homered for the first-place Marlins, who won their fourth game in a row and matched their best start after 34 games (20-14).

The Brewers lost their sixth game in a row, their longest losing streak this year. They finished 1-5 in the season series against Florida, scoring a total of 10 runs.

Milwaukee stranded 11 runners against four Florida pitchers. Marlins starter Mark Hendrickson needed 109 pitches to get through 4 1-3 innings but allowed only one run.

Logan Kensing (1-0) retired all eight batters he faced, striking out four. Florida's Luis Gonzalez went 3-for-3 with a walk and finished the series 7-for-11.

Carlos Villanueva (1-4) allowed seven runs in five innings to remain winless since his first start of the season April 4. His ERA rose to 6.46.

Trailing 3-1, Villanueva was a strike from retiring the side in order in the fifth, then gave up four runs. Dan Uggla walked on a 3-2 pitch, Gonzalez reached on an infield single, Wes Helms singled home a run and Treanor hit a three-run homer off the foul-pole screen, his first.

Treanor, who is in his fifth major-league season, never previously had more than two RBIs in a game.

Hanley Ramirez singled with two out in the first, stole second and took third when the throw was errant. Cantu hit his fifth homer on the next pitch to put Florida ahead 2-0.

Jeremy Hermida led off the third with a soft liner that bounced past left fielder Ryan Braun for a double. Ramirez followed with an RBI single.

The Brewers scored their first run thanks to a lapse by Hendrickson with two out in the fourth. He allowed catcher Mike Rivera to steal second without a throw -- the first stolen base of his career -- and Villanueva followed with an RBI single.

Villanueva, who came into the game with a career average of .051, singled twice. Rivera singled home a run in the eighth, but that was as much offense as the Brewers could muster, and they finished a three-city trip with a 2-7 record.
