Matt Garza pitched into the ninth inning and Anthony Rizzo hit his first home run since May 18 to lead the Chicago Cubs over the Houston Astros 3-1 on Friday after a rain delay that lasted more than 3 hours.

The subject of trade speculation, Garza (2-1) allowed four hits and struck out eight in eight-plus innings for his first win since beating Arizona on May 31.

Garza, who threw seven scoreless innings last Sunday against the Mets but did not get a decision, walked Jose Altuve to begin the ninth and was replaced by Kevin Gregg, who earned 11th save in 11 tries.

Chris Carter broke up Garza's shutout bid with a leadoff homer in the seventh. Carter's 15th home run was a sharp line drive to right-center.
