PITTSBURGH (AP) -- Pinch-hitter Jayson Werth hit a tying two-run homer, Chris Heisey drove in the go-ahead run, and the Washington Nationals scored five runs off former teammate Felipe Rivero in the eighth inning to rally past the Pittsburgh Pirates, 10-7 on Sunday.
Clint Robinson added an RBI single and Pedro Severino drew a bases-loaded walk in the inning. Rivero (1-5) had allowed just four earned runs in his previous 25 innings since being traded to the Pirates.
Jung Ho Kang hit a two-run homer off Koda Glover to give the Pirates the lead in the bottom of the seventh, but Glover (3-0) got the win with the Nationals' offensive outburst the following half inning.
Former Pirates closer Mark Melancon pitched a scoreless ninth for his 43rd save.
With the division title clinched the night before, it seemed the Nationals were poised for an uneventful series finale against the Pittsburgh Pirates on Sunday afternoon.
That wasn't to be, as the two clubs engaged in a benches clearing altercation in the bottom of the third inning. The tension started in the top of the frame, when Bryce Harper was injured while sliding to third base on a triple. The Nats took exception to Pirates third baseman Jung-ho Kang faking a tag on Harper, which may have led to the injury.
So when Nats starter A.J. Cole threw behind Kang in the bottom of the inning, the near-fracas was ignited.

Cole was immediately ejected from the game, benches cleared, and each side exchanged words. The Pirates' Sean Rodriguez was also ejected from the game.
