PITTSBURGH — Coming off two subpar outings, Chad Kuhl went into the video room to find some past success he could recreate.

Kuhl and four relievers combined on a three-hitter, and the Pittsburgh Pirates scratched out the only run of a rainy game Sunday when David Freese was hit by a pitch with the bases loaded in a 1-0 victory over the Philadelphia Phillies.

Kuhl used his sinking, two-seam fastball to rack up quick outs. He allowed his only hit in the fifth inning.

“I looked back, watched a ton of video and tried to get back to when I was good,” the second-year pitcher said. “It feels great to have it show up in the game — all the work paying off. It just feels like I’m on the right track.”

Philadelphia starter Aaron Nola (2-1) got back on track, as well. Nola returned from the disabled list and threw seven strong innings. The right-hander, who had been sidelined with a back injury, gave up four hits and faltered just briefly in the sixth.

Adam Frazier and Josh Harrison started the inning with consecutive singles, putting runners at the corners. Harrison stole second and, after Andrew McCutchen grounded out, Josh Bell was intentionally walked to load the bases. Nola hit Freese with a pitch, forcing in a run, before John Jaso grounded into an inning-ending double play.

“I’m not really good about getting out of the way, anyway,” Freese said. “But I saw it coming and I was trying to wear it, for sure. Just get that RBI.”

Philadelphia lost for the ninth time in 11 games. But the 23-year-old Nola struck out five and had thrown 89 pitches when he was removed for a pinch hitter in the eighth.

“What a breath of fresh air that was,” Phillies manager Pete Mackanin said. “He looked like his old self today. That’s the thing that I take out of this game that I’m really happy about. The only run scored was on a hit batsman. He looked like his old self and I’m really happy about that. That’s about all I’m happy about today.”

Wade LeBlanc (3-0) pitched 1 1/3 innings to win in relief. Juan Nicasio and Felipe Rivero got the ball to Tony Watson, who earned his 10th save in 11 opportunities.

Pittsburgh’s bullpen has been pitching well of late, and that’s what gave manager Clint Hurdle the confidence to pull Kuhl for a pinch hitter in the fifth.

The game started on time and was never delayed but was played during a steady rain that became heavy at times.

Frazier finished 2 for 3 with a walk to increase his batting average to .369. He would rank second in the National League if he had enough plate appearances to qualify.
