Carlos Zambrano picked up his first win in a Marlins uniform Monday and helped extend Miami's win streak to seven games, all on the road, with a 4-0 victory over the Astros at Minute Maid Park.

Zambrano (1-2) pitched well enough to win in his five previous starts, with a 2.53 ERA in 32 innings, but the Marlins suffered blown saves in three of them. Zambrano took no chances this time, throwing a complete-game three-hitter. He struck out nine and gave up just three singles. He walked only one, but did hit two batters.

The right-hander did not allow a runner past first base all night long. Four double plays turned by the Marlins' infield helped keep Astros baserunning to a minimum. Zambrano threw 110 pitches, 69 for strikes.

Marlins manager Ozzie Guillen summed it up in one word: "Strikes."

"First victory, complete game, what more could I ask for," Zambrano said. "Everything was working and I was using all my pitches."
