PITTSBURGH (AP) — Christian Bethancourt drove in seven runs, including a go-ahead two-run single in the ninth, as the Chicago Cubs rallied past the Pittsburgh Pirates 14-10. The Cubs trailed by seven through six innings before taking advantage of another shaky performance by Pittsburgh’s bullpen to complete the three-game sweep. Bethancourt hit a two-run homer in the seventh to start the rally. The catcher added a two-run double in the eighth and laced a sharp bases-loaded single to left against Pirates closer David Bednar to finish the comeback. Pirates rookie ace Paul Skenes struck out six in five innings and was in line for his ninth victory before the Cubs rallied.
