Pittsburgh, PA (SportsNetwork.com) - The way the Braves have been hitting, the Pirates needed a lot more than the return of Andrew McCutchen to slow them down.
Justin Upton homered and drove in five runs to highlight Atlanta's fifth straight win, an 11-3 drubbing that sent Pittsburgh to a seventh consecutive loss.
Jason Heyward added two hits and three RBI and Evan Gattis hit a solo homer for the Braves, who have scored 33 runs during their winning streak.
Aaron Harang (10-7) tossed 8 1/3 innings and limited Pittsburgh to three runs on nine hits to pick up his first victory since July 10.
"He navigates through lineups and he doesn't give you anything good to hit over the middle of the plate," Braves manager Fredi Gonzalez said of Harang.
McCutchen went 0-for-4 in his return from missing two weeks with a fractured rib, and all the Pirates managed offensively was an RBI groundout from Neil Walker in the fourth and run-scoring singles from Brandon Cumpton and Ike Davis in the sixth and ninth, respectively.
"We haven't played a complete game," Pittsburgh manager Clint Hurdle said of the losing streak.
Otherwise, it was all Braves, who hammered Francisco Liriano (3-10) for nine runs -- seven earned -- on 10 hits over the first four-plus innings.
Harang helped himself with a two-out, RBI single in the second inning, and Upton, who was playing in his 1,000th career game, reached the left-field stands for a three-run homer in the third.
Heyward tacked on an RBI single in the fourth, and after the Pirates got on the board in the bottom half, Atlanta broke it open with a five-spot in the fifth.
An error, single and walk loaded the bases for B.J. Upton, whose base hit drove in a run and ended Liriano's outing. Heyward and Justin Upton both singled in a pair for a 10-1 cushion.
Gattis' mammoth ninth-inning blast down the left-field line capped the rout.
