Niese pitched seven sharp innings and Justin Turner added to his surprising tear with a two-run double that sent New York to a 3-0 victory over the light-hitting Washington Nationals on Wednesday night.

"I've never played in anything like that," Niese said. "It's the wettest I've ever been pitching. ... Every ball the umpire gave me was wet. I had to do my best to rub them dry in my hands."

With maybe a few thousand hardy souls in the stands on another soggy night at Citi Field, the Mets' depleted lineup scratched out enough offense to help Niese (3-4) win his second consecutive start.

Playing without injured regulars David Wright, Ike Davis and Angel Pagan, New York won for the eighth time in 12 games and tied Washington for fourth place in the NL East.

Jason Bay had a sacrifice fly in the first inning and Turner cracked a two-out double in the sixth to chase Tom Gorzelanny (2-3) after 116 pitches. Jose Reyes singled three times, drew an intentional walk and scored twice from his leadoff spot.

"Everybody's not thinking about who isn't here, they're thinking about making the most of their opportunities," Niese said.

With deep puddles forming on the infield, Jason Isringhausen worked a one-hit eighth and Francisco Rodriguez got three outs for his 13th save in 14 chances. K-Rod blew his first opportunity of the season, but has tossed 17 straight shutout innings dating to April 17.

With two on, he retired pinch-hitter Laynce Nix and then Roger Bernadina on consecutive flyouts to left.

New York allowed eight hits in its first shutout this year. Washington was blanked for the sixth time.

Quiet nights at the plate are nothing new for the Nationals. They began the day ranked last in the NL in batting average (.225), on-base percentage (.298), slugging (.348), hits (302), total bases (467) and doubles (57).

"There's nothing to do except work your way out of it," manager Jim Riggleman said.

Both teams were rained out Tuesday night -- the Nationals at home against Pittsburgh, and the Mets at home against the Marlins. That came after New York and Florida played through the mist on a muddy track Monday night.

The announced attendance Wednesday was 24,527, but nearly all the seats were empty and hecklers could be heard from the stands.

"It was wet and rainy just like it looked, but I think all of us were kind of itching to play," Nationals shortstop Ian Desmond said. "We were ready to get back out there."

After some torrential rain in the afternoon, the heavy stuff stopped in time to start the game on time -- with no more than a couple hundred fans in the ballpark.

The grounds crew worked hard between innings all night to try to dry out the infield and it was absolutely pouring when Bernadina grounded out with the bases loaded to end the seventh.

Still, play went on without interruption.

Niese gave up six hits and one walk, striking out seven. The left-hander threw 72 of 112 pitches for strikes.

"He's certainly showing he can pitch in a jam," Mets manager Terry Collins said. "W our lineup shaken up a little bit, we've got to pitch."

Reyes hit a leadoff single in the first, went to third on Turner's double and scored on Bay's sacrifice fly.

Scott Hairston reached on an infield single to start the sixth, easily beating a throw from his brother, Jerry, at third base. With two outs and first base open, Reyes was intentionally walked to bring up Turner. He doubled to center over the head of the speedy Bernadina, who was playing shallow.

Before that hit, New York was 0 for 9 with runners in scoring position.

Turner, called up from the minors last month to share playing time at second base, has provided an offensive spark. He shifted to third base Wednesday to fill in for Wright and is hitting .387 with 11 RBIs in his last nine games.

Turner hit his first major league homer and drove in a career-best five runs Sunday in Houston to lead the Mets to a victory.

"It's all about taking advantage of opportunities," he said. "It's a little easier to take your at-bats and get comfortable when you see your name in the lineup."

Game notes
Nationals GM Mike Rizzo said RHP Stephen Strasburg is preparing to throw off a mound "any day now," the next step in his recovery from Sept. 3 elbow surgery. ... Washington OF Rick Ankiel (right wrist) is close to beginning a minor league rehab assignment and could be back in about a week. ... As planned, the Mets put Wright (lower back) on the 15-day DL, retroactive to May 16, and called up 1B-OF Nick Evans from Triple-A Buffalo. ... Collins said he plans to tweak his depleted lineup in the next couple of days, perhaps moving Bay into the No. 2 hole.
