Ben Zobrist broke a tie with a two-run double and Kris Bryant followed two batters later with a two-run single, powering a four-run seventh inning that sent the Chicago Cubs to a 6-2 victory over the San Francisco Giants in the opener of a three-game series in Chicago. Kyle Hendricks limited the Giants to two hits and one run over seven innings for the Cubs, who busted out after having been held to one run in two games by the Cleveland Indians earlier in the week. Gorkys Hernandez homered for the Giants, who have scored just five runs in three games on a trip that began with a pair of losses in Houston.
