Anibal Sanchez pitched seven scoreless innings and Cody Ross and Hector Luna hit back-to-back homers to power the Florida Marlins to a 9-0 win over the Houston Astros on Friday night.

Dan Uggla and Emilio Bonifacio each drove in a pair of runs for the Marlins, who have won four straight.

Sanchez (10-8) allowed three hits and one walk while striking out five. He is 3-0 with a 0.70 ERA in four starts against the Astros.

J.A. Happ (3-2) retired 10 straight before a 37-minute rain delay. He was charged with three runs in six innings and struck out six.

The Marlins led 3-0 in the seventh before Sanchez delivered a run-scoring single.

It was his first RBI in 103 at-bats since Sept. 11, 2006 against the New York Mets, a span of 103 at-bats.
