Even with star players resting or nursing minor injuries and manager Mike Matheny's mixing and matching, the St. Louis Cardinals keep slugging and are never content with a late lead. Harrison Bader hit a tiebreaking homer in the decisive sixth inning after Madison Bumgarner homered in the bottom of the fifth, and the Cardinals beat the San Francisco Giants 7-3 on Sunday to gain ground again in the wild-card race. ''It's big, especially against Madison,'' Jose Martinez said.
