PITTSBURGH — Patrick Corbin pitched eight scoreless innings to remain unbeaten in more than two months, and Asdrubal Cabrera’s three-run home run capped a six-run third as the Washington 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.

Signed to a six-year, $140-million contract in free agency in December, Corbin has not lost since June 11. The left-hander is 5-0 with a 2.12 ERA in 12 starts since then.

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.

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 center field to make it 6-0.

It was Cabrera’s second home run since being claimed Aug. 6 off waivers from Texas.
