Jayson Werth broke a tie game with a tape- measure three-run homer in the fifth inning to power the Washington Nationals past the Arizona Diamondbacks, 8-4, in the opener of a season-ending three- game series.
Werth reached base in all four of his plate appearances and Wilson Ramos added a three-run homer to back a strong outing from Stephen Strasburg (8-9), who gave up two runs on six hits over seven innings.
The Nationals snapped a three-game skid by touching up Patrick Corbin (14-8) for five runs on six hits in the first five innings.
"I felt fine and healthy and made it through a full season," said Corbin. "Hopefully next year I can improve and get better and learn from my mistakes."
Arizona dropped its third straight game despite taking an early 2-0 lead.
Strasburg, making start No. 30 for the first time in his career, put the first three hitters on in the third and gave up an RBI single to Gerardo Parra and a run-scoring, double-play groundout to Paul Goldschmidt.
"You've got to grind through it, and I was able to make the adjustments in the end."
Werth scored from first on Bryce Harper's double in the fourth inning, then capped a four-run fifth with a colossal go-ahead blast off the second-deck facade in left field. Tyler Moore and Anthony Rendon opened the frame with consecutive doubles, the latter knocking in Moore with the tying run.
Ramos blew the game with a three-run homer off Chaz Roe in the eighth.
Arizona got two runs in the ninth on Didi Gregorius' RBI groundout and pinch- hitter Matt Davidson's RBI single.
Strasburg went 3-0 over his final nine starts and lowered his ERA to 3.00 ... Goldschmidt extended his hitting streak to 17 with a single in the fifth inning ... Corbin's ERA rose from 2.92 to 3.41 over his final three starts.
