CHICAGO (AP) David Ross homered and teamed with Jon Lester for another scoreless performance, and the Chicago Cubs hurt St. Louis' wild-card chances with 3-1 victory over the Cardinals on Sunday night.
Ben Zobrist had three hits and scored two runs as Chicago finished with a major league-best 57-24 home record. It's the most home wins for the Cubs since they went 58-19 at the West Side Grounds in 1910.
The Cardinals lost for the third time in four games, wasting a chance to improve their playoff positioning. They remain a half-game back of San Francisco for the second NL wild card.
Lester (19-4), one of the top candidates for the NL Cy Young Award, struck out seven in 6 2/3 innings. The left-hander allowed three hits and walked one while improving to 10-0 with 1.34 ERA in his last 13 starts.
Carlos Martinez (15-9) allowed two runs and six hits in six innings.
