PITTSBURGH — Patrick Corbin gave the Nationals another stellar outing in his first season in Washington.

Corbin, signed to a six-year, $140 million deal last winter, pitched eight scoreless innings to remain unbeaten in more than two months, and Asdrúbal Cabrera had a three-run home run in a six-run third as the Nationals rolled to an 11-1 victory over the Pittsburgh Pirates on Wednesday night.

Corbin (10-5) struck out four and walked two while throwing 93 pitches to help the Nationals maintain their lead atop the National League wild-card standings.

"He was really good," Martinez said. "He pounded the strike zone and kept everything down. He was awesome."

Corbin has not lost since June 11. The left-hander is 5-0 with a 2.12 ERA in 12 starts since then.

"He just throttled us," Pirates manager Clint Hurdle said. "We had no answers."

Corbin was three outs away from his second shutout this season and third of his seven-year career. However, with the Nationals ahead 11-0, Washington manager Dave Martinez decided to have Tanner Rainey pitch the ninth inning.

"It's a long season and why not save some pitches, really, and give someone else some work?" Corbin said. "I don't blame (Martinez)."

Joe Musgrove (8-12) gave up six runs and seven hits in five innings as Pittsburgh lost for the 29th time in 37 games since the All-Star break.

"I didn't really have good stuff tonight from the bullpen all the way out through the fifth inning," Musgrove said. "It was just one of those nights where I was battling the best I could."

Adam Eaton opened the scoring in the third with an RBI double and Anthony Rendon followed with a two-run single, giving him 100 RBIs. Following a walk to Juan Soto, Cabrera hit a drive to straightaway centre field to make it 6-0.

It was Cabrera's second home run since being claimed Aug. 6 off waivers from the Texas Rangers and 14th overall. He was filling in at second base for Brian Dozier, who is on paternity leave.

Cabrera believes being reunited with hitting coach Kevin Long has helped. They also worked together with the New York Mets.

"He knows when I'm swinging the ball well and when I'm not," Cabrera said. "I feel very comfortable with him."

Corbin retired 11 batters in a row until Jacob Stallings and Erik González hit consecutive singles with one out in the fifth inning. However, Corbin escaped the jam by getting pinch-hitter Melky Cabrera to fly out and Kevin Newman to ground out.

Washington added three runs in the eighth when Yan Gomes hit a two-run double and scored on a double by Corbin. In the ninth, pinch-hitter Adrian Sanchez and Trea Turner hit back-to-back RBI singles.

Turner has reached base safely in a career-best 28 straight games.

Josh Bell's run-scoring double in the ninth prevented the Pirates from being shut out.

TRAINER'S ROOM

Nationals: RHP Joe Ross (bruised right shin) will throw a bullpen session Thursday before the team determines whether he can make his next scheduled start Saturday against the Cubs at Chicago. Ross left in the fourth inning of Monday's game after being hit by a hard one-hopper by Pirates 1B Bell. If Ross is unable to pitch, RHP Eric Fedde will start instead.

Pirates: RHP Chris Archer (right shoulder inflammation) and RHP Clay Holmes (right quadriceps discomfort) were placed on the injured list. Archer left Tuesday's game with the Nationals after the first inning and Holmes followed by pitching 3 2/3 innings. Archer will not throw for at least a week then be evaluated. ... RHP Dario Agrazal and RHP Parker Markel were recalled from Triple-A Indianapolis. Agrazal is expected to start Sunday against the Cincinnati Reds. ... RF Gregory Polanco (right shoulder inflammation) has started participating in baseball activities at the team's spring training facility in Bradenton, Fla.

MINOR MOVE

The Nationals signed veteran LHP Sam Freeman as a free agent and assigned him to Triple-A Fresno. Freeman made one relief appearance for the Los Angeles Angels earlier this season and has also pitched in the major leagues with four other teams.

UP NEXT

Nationals: RHP Max Scherzer (9-5, 2.41 ERA) is on course to be activated from the IL and start in the finale of the four-game series. The three-time Cy Young Award winner has been out since July 26 with a mid-back strain.

Pirates: LHP Steven Brault (3-2, 4.06) looks to snap a six-start winless streak.
