Washington - Jayson Werth hit a three-run home run, and Yunesky Maya, filling in for traded starter Jason Marquis, earned his first career win for the Washington Nationals in a 3-0 victory over the New York Mets on Saturday night.

Maya (1-1) allowed five hits in 5 1-3 scoreless innings after being recalled from Triple-A Syracuse when Marquis was traded to the Arizona Diamondbacks shortly before the game. Maya, who made his major league debut with Washington last season, was making his fourth start of the season and 10th of his career. He entered the game with an 0-4 career record.

Maya entered the Nationals clubhouse in street clothes about an hour before game time and about 45 minutes before Washington announced the trade. The late notice didn't seem to affect him as he retired the first seven batters and didn't allow a hit until David Wright singled with two outs in the fourth.

Maya didn't walk anyone - or record a strikeout - although he hit a batter. He gave up consecutive singles in the sixth to Daniel Murphy and Wright, leading Nationals manager Davey Johnson to bring in reliever Ross Detwiler, who promptly got Angel Pagan to ground into a double play.

Drew Storen pitched the ninth for his 26th save in 29 chances, although he gave up a walk and two singles, loading the bases with two outs. Pinch-hitter Willie Harris stuck out looking to end the game.

Washington grabbed the lead in the first inning. Rick Ankiel led off with a single against R.A. Dickey (5-9) and advanced to third on a sacrifice and wild pitch. Dickey walked Michael Morse to put runners on the corners for Werth, who drove a 3-2 pitch deep to center field for his 12th home run of the season.

The homer gave the Nationals a lead for the first time in six games, since going up 1-0 in the top of the first inning against the Los Angeles Dodgers on July 24.

New York had perhaps its best offensive chance in the fifth. A pair of two-out singles by Josh Thole and Dickey brought up Jose Reyes with runners on first and second. Reyes hit a ball deep to right-center but Werth caught it on the warning track to end the inning.

NOTES: The Nationals traded utilityman Jerry Hairston Jr. to Milwaukee for OF Erik Komatsu, who was with Double-A Huntsville. Washington recalled OF Brian Bixler from Triple-A Syracuse to fill Hairston's roster spot. ... Wright had two singles, giving him a career-high seven consecutive multihit games. Wright has a hit in all nine games since he returned from the disabled list (lower back stress fracture) on July 22.
