CHICAGO (AP) -- Michael McKenry and Starling Marte homered to back a strong start by Jeff Karstens, and the Pittsburgh Pirates beat the Chicago Cubs 8-4 on Wednesday.
Garrett Jones added two hits and drove in three runs after entering in the eighth as a pinch-hitter. Andrew McCutchen chipped in with two hits and scored three times, and the Pirates pulled away late.
Clinging to a 2-1 lead, Pittsburgh started a five-run eighth with seven straight hits against Shawn Camp and sent 10 batters to the plate in the inning.
Jones, batting for Gaby Sanchez, drove in two with a single and McKenry made it 7-1 with a three-run drive to left -- his 10th homer. Just like that, the Pirates could breathe a little easier.
