CHICAGO (AP) - Cody Ransom hit a tiebreaking, three-run homer in the seventh inning and Edwin Jackson pitched the Chicago Cubs to a 4-1 victory over the Pittsburgh Pirates on Sunday.
Ransom connected off reliever Justin Wilson for his sixth home run of the season. Darwin Barney and Julio Borbon were on base after the Cubs were held hitless for 5 2-3 innings by Pirates starter Jeff Locke.
Jackson (2-8) had his best and longest outing of the season, striking out eight in seven innings. He allowed four hits and a walk as the Cubs salvaged the finale of a three-game series.
Kevin Gregg pitched the ninth for his seventh save, completing a six-hitter.
Chicago manufactured a game-tying run in the sixth before Dioner Navarro got the team's first hit on a two-out single to left.
