Jonathon Niese pitched a one-hitter for his first career complete game and the New York Mets overcame a tripleplay to beat the visiting San Diego Padres, 3-0, last night for a doubleheader split.

Niese (3-2) allowed only Chris Denorfia's leadoff double in the third inning, his second stellar start since coming off the disabled list Saturday. He faced 28 batters, one more than the minimum, in New York's first complete game this season.

Mat Latos (6-4) outpitched Johan Santana (4-3) in the opener, and San Diego stopped New York's nine-game home winning streak with a 4-2 victory.

Adrian Gonzalez had three hits for the Padres, including a go-ahead single. David Eckstein and Chase Headley added RBI doubles.

Niese topped that, however, striking out six and walking none in his fifth career win. He retired his last 21 in a game that took only 2 hours, 18 minutes.

The last Mets pitcher to throw a complete-game, one-hitter that lasted the full nine innings was Aaron Heilman on April 15, 2005, against Florida.

Pop-music star Lady Gaga, sitting in a luxury suite, was photographed making an obscene gesture before the opener. It was unclear what prompted the gesture, and the Mets say she did not attend the second game.
