Cubs 4, Astros 0
CHICAGO — The Cubs used three homers — Steve Clevenger (first of career), Luis Valbuena and Alfonso Soriano — to help Paul Maholm get his first win since May 9. He entered 0-4 with a 6.43 ERA over his previous eight outings but outdueled Bud Norris, who came off the DL after missing 2½ weeks with a sprained left knee. Clevenger's two-run shot in the fourth made it 3-0. All 15 of Soriano's homers have come since May 15.
