Washington right-hander Austin Voth (2-5) needed 36 pitches to escape the first but made it through five innings to close his season with back-to-back victories. Voth allowed four runs while striking out four.

The Nationals chased Mets starter Seth Lugo after 1 1/3 innings. Lugo (3-4) allowed six runs on five hits and two walks.

With Washington already leading 7-3, Turner busted the game open with a third-inning grand slam off reliever Steven Matz. It was Washington’s first grand slam of the season.

Washington and INF Howie Kendrick have a mutual option for 2021, and he has at least one prominent figure hopeful for his return.

“I’m holding onto his leg,” manager Dave Martinez said. “He’s got a lot of discussions to have with his family and I told him we’ll stay in touch as we always do and we’ll see where he’s at.”

The 37-year-old Kendrick hit .275 with two homers and 14 RBIs in 25 games, and ended the season on the injured list with a left hamstring strain.

Soto was named Washington’s player of the year and RHP Max Scherzer (5-4, 3.74 ERA) earned the team’s pitcher of the year award in voting by local media. LHP Sean Doolittle won his third consecutive Good Guy Award.
