CHICAGO (AP) — Gregory Polanco hit a two-run homer in the sixth inning and Ivan Nova pitched three-hit ball into the seventh, leading the Pittsburgh Pirates to a 4-2 victory over the Chicago Cubs on Saturday night.
Josh Bell had three hits and two runs scored, while Francisco Cervelli and Jordy Mercer each drove in a run for the Pirates.
Ian Happ and Kyle Schwarber had back-to-back home runs for Chicago, which has not won consecutive games since a three-game streak June 18-20.
Nova (9-6) struck out six and walked one in 6 2/3 innings. Besides the homers, the only other hit he allowed was a second-inning single to Schwarber.
Felipe Rivero, who reached 102 on the radar gun, got the final four outs for his sixth save.
Cubs starter Jake Arrieta (8-7) allowed four runs (three earned) and six hits in 5 2/3 innings. He had allowed an unearned run through five innings before being knocked out in the sixth.
