Cubs 6, Rockies 4

CHICAGO (AP) - Carlos Zambrano won for the fourth time in five starts, and the surging Chicago Cubs beat the Colorado Rockies 6-4 Wednesday to extend the Rockies losing streak to 6 games.

Mark DeRosa hit a three-run homer and Mike Fontenot added a solo shot for Chicago, on its longest winning streak since a seven-game run from May 27-June 2, 2005. Colorado has lost a season-high six straight since sweeping three games from the New York Yankees.

Zambrano (9-6) allowed two runs and five hits in six innings, improving to 4-1 since his dugout and clubhouse fight with former teammate Michael Barrett on June 1. In his only loss during that five-game stretch, he took a no-hit bid into the eighth against San Diego before losing 1-0.

Carlos Marmol struck out two in a perfect ninth for his first career save, finishing a six-hitter.

Jason Hirsh (3-7), a 6-foot-8 right-hander, gave up five runs and five hits in six innings. Colorado is on its longest losing streak since a six-game skid last August.

Ryan Theriot hit an RBI single in the second, and DeRosa connected for his seventh homer of the season with two outs in the third following walks to Derrek Lee and Cliff Floyd.

The 5-foot-8 Fontenot, a 27-year-old-rookie the Cubs acquired in a 2005 trade with Baltimore for former star Sammy Sosa, hit his third homer to make it 5-0 in the fourth, a long drive to the back of the bleachers in right. Fontenot, called up from Triple-A on June 9, earlier extended his hitting streak to 10 games when shortstop Troy Tulowitzki lost his pop in the sun and it fell for a single. He added a double in the seventh.

Fontenot, 3-for-4 Wednesday and 5-for-5 Monday, finished the series 9-for-13.

After Zambrano struck out Garrett Atkins with the bases loaded and one out in the sixth, Brad Hawpe dumped a 3-2 pitch into right for a two-run single.

Angel Pagan's sacrifice fly in the seventh put the Cubs up it 6-2. But Atkins hit a two-run homer in the eighth off rookie Billy Petrick, who made his major league debut after being called up from Double-A on Tuesday.

Notes: Cubs 3B Aramis Ramirez was given the day off to rest and DeRosa filled in with a couple of nice defensive plays.
