WASHINGTON (AP) -- Doug Fister took a five-hit shutout into the eighth inning, Adam LaRoche homered twice and Danny Espinosa also connected as the Washington Nationals beat the New York Mets 6-1 Wednesday night.

Fister (11-3) allowed one unearned run and six hits in 7 1-3 innings. He struck out seven and reduced his ERA to 2.49.

LaRoche hit a two-run drive in the first inning and a solo shot in the eighth, his 23rd career multihomer game. Espinosa went deep with two on in the sixth and Anthony Rendon hit two doubles to help NL East-leading Washington increase its lead over sputtering Atlanta to four games.

Mets starter Jonathon Niese (5-8) gave up a season-high six runs on eight hits in six innings. It was only the second time in his last 25 starts the left-hander yielded more than three earned runs.
