Many on the Dodger side of the field thought Wright was out when a 2-2 slider just missed the outside corner but Wright spanked a 3-2 fastball up the middle to score two and gave the Mets their major league-leading 29th one-run victory.
Maddux (12-13), who gave up a homer to Delgado leading off the second, only fourth hit in 21 trips off Maddux and was 2-for-15 on the homestand before his long shot.
Orlando Hernandez hadn't faced Greg Maddux since the 1999 World Series, and this game had the feel of a post-season game about it. Maddux lost his second straight start and fell to 3-2 in eight starts with the Dodgers.
Hernandez outpitched Maddux, giving up only one earned run in seven innings, and Wright's two-run single off Tomko tagged the Dodger ace with the loss.
It was the second victory for New York in the third game of four between N. L. division leaders. The Mets lowered their magic number for clinching the East to six, while Los Angeles clung a 1 1/2 -game lead over San Diego, which lost for the second time to San Francisco.
However, the Giants, winners of three in a row, are only three games behind the Doddgers now.
The Dodgers lost an opportunity in the first inning after Rafael Furcal doubled on the second pitch of the game. He was bunted to third by Kenny Lofton but Nomar Garciaparra flew softly to right and J.D. Drew struck out.
Then El Duque retired 15 straight Dodgers, six on strikeouts, before Russell Martin singled to open the sixth and advanced to second when Maddux faked a bunt and swung away.
Shortstop Jose Reyes had broken for second, and had to reverse his field to reach the ball hit into the hole. His throw to first glanced off the glove of Delgado's glove, allowing Maddux to reach on the error.
Furcal bunted them to second and third before Lofton drove in Martin with a single to center. Maddux advanced on the base hit, then was caught in a rundown between third and home when Nomar Garciaparra grounded into a fielder's choice. J.D. Drew followed with a broken-bat single to drive in Lofton and put L.A. in front 2-1. Jeff Kent bounced out, leaving runners on first and second.
Valentin doubled to open the sixth and manager Grady Little talked to Maddux about an intentional walk to Beltran and then Hamulak replaced Maddux who had thrown 72 pitches.
"I was tired," Maddux said. "We talked leaving after the intentional walk and I agreed."
Tim Hamulack got Delgado -- who hit his 37th homer in the second inning -- on a long fly to center before Wright's hit gave the Mets a 3-2 lead. Hernandez won for the third time in five starts and has allowed only two earned runs in three outings since yielding a career-worst 11 in four innings at Philadelphia on Aug. 15.
The Dodgers had one last gasp in the ninth. Kent singled with one out and was replaced by pinch-runner Jason Repko. After pinch-hitter Olmedo Saenz struck out, Repko was nailed attempting to steal second to end the game.
