Pirates 5, Rockies 3

PITTSBURGH -- Pittsburgh was once again able to wait out the Colorado's starting pitcher and attack the bullpen.

Andrew McCutchen knocked in the go-ahead run with a single in the seventh and Neil Walker added insurance two batters later with his 14th home run to propel the Pirates. Walker finished 3-for-4 with two runs while leading his team to its second series sweep of the year.

Pittsburgh left-hander Jeff Locke worked six innings and gave up three runs on seven hits and two walks.
