David Peterson dominated the Nationals again, Mark Vientos homered for the second consecutive game and the New York Mets pounded Washington 8-1 on Tuesday night for their third straight victory.
Peterson (8-5), who blanked the Nats on June 11 in New York for his first career shutout, extended his scoreless streak against Washington to 25 innings dating to last season. He finally allowed a run when Dylan Crews led off the eighth with a triple and scored on a double-play grounder.
The only Mets starter who has reliably pitched deep into games, Peterson finished the eighth.
