Moran’s homer, his 10th of the season, to deep center field in the first inning opened the scoring. The Pirates scored four runs in the sixth to move ahead 7-6. Moran singled home an insurance run in the seventh.
Coming into the game, Moran was hitting just .186 in 22 games in September.
“He’s starting to swing at the right pitches,” Pirates manager Derek Shelton said. “When he does that, a hitter of his caliber is going to get hits.”
Bryan Reynolds had three hits and scored three times for Pittsburgh, which won for the second time in six games. His single started the sixth-inning rally.
Moran had two hits and drew two walks, and Jacob Stallings also had two hits for the Pirates.
Moran hits cleanup behind Reynolds in the batting order, and the duo combined for five hits.
“Hitting behind him is fun. It’s fun to watch him work up there,” Moran said of Reynolds, who is hitting .296. “I get a good feel for how they are pitching him and hopefully him being on base leads to me getting some good pitches to hit.”
Down 6-3, the Pirates rallied in the sixth inning. Ben Gamel’s sacrifice fly made it a two-run game, and Hoy Park drove a tying two-run triple to center field. Pinch-hitter Michael Chavis singled in Park with the go-ahead run.
Chris Stratton worked a scoreless ninth inning for his seventh save, as the Pirates snapped a seven-game losing streak to the Cubs.
“I got in some good counts then left some balls over the heart of the plate. You can’t leave it there,” Keller said. “The bullpen came in and put up zeroes and we kept adding on runs. The rest of the guys had my back.”
Mills is 0-2 with a 7.82 ERA in five September starts.
“To be honest, this is one of the worst stretches of pitching I’ve ever had,” Mills said. “It’s frustrating.”
The Cubs went ahead 6-3 with three runs off Keller in the fifth. Ian Happ hit an RBI single, Duffy doubled in a run and Martini lifted a sacrifice fly.
After Moran put the Pirates ahead 3-0, the Cubs tied it with a three-run third that included run-scoring singles by Schwindel, Duffy and Martini.
