CHICAGO — Madison Bumgarner outpitched Jake Arrieta with 10 strikeouts over six innings, and the San Francisco Giants pounced on rare miscues by the Chicago Cubs in a 3-2 victory on Saturday.
Bumgarner (14-8) allowed two runs and five hits in his fourth victory in his last five starts. San Francisco, trying to catch Los Angeles in the NL West, rebounded from a pair of one-run losses in the first two games of the four-game set against the major league leaders.
Arrieta (16-6) was charged with three runs — two earned — and four hits in six innings in his first loss since July 30. The Cubs had won five in a row overall.
