Cubs 3, Astros 0
CHICAGO — Travis Wood took a shutout into the eighth inning, Anthony Rizzo hit a go-ahead single and the Cubs completed a three-game sweep. Wood pitched a season-high 7⅔ innings and left the game to a loud ovation after retiring Brian Bixler in the eighth. The 25-year-old left-hander has yielded one run over 20⅔ innings in his past three starts. Chicago scored three in the sixth. Wood led off with a double, and Rizzo hit an RBI single off Wandy Rodriguez.
