NEW YORK -- Jordany Valdespin's grand slam in the bottom of the 10th inning Wednesday night lifted the New York Mets to a dramatic and stunning 7-3 win over the Los Angeles Dodgers in front of 24,130 at Citi Field.
Valdespin's walk-off grand slam just beyond the right-field fence was the first for the Mets since Kevin McReynolds did it against the Expos on June 25, 1991.
Valdespin pumped his fists as he ran between second and third, flung his helmet skyward between third and home and leaped twice, the last time into a group of teammates.
David Wright's two-out RBI single in the ninth sent the game to extra innings. The Mets had stranded nine runners, including seven in scoring position, before Ruben Tejada raced home with the tying run on Wright's hit.
Bobby Parnell, the Mets' fifth pitcher, earned the win with a scoreless 10th. Four Mets relievers combined to throw no-hit ball over the final four innings.
In the 10th, John Buck led off with a single before Ike Davis drew a four-pitch walk from losing pitcher Josh Wall. Marlon Byrd followed with a bunt to advance the runners, after which Wall intentionally walked Lucas Duda to bring up Valdespin, who crushed Wall's fourth pitch.
Matt Kemp had a replay-aided two-run homer in the sixth and finished with all three of the Dodgers' RBIs.
Mets pinch-hitter Mike Baxter opened the ninth with a double that glanced off the glove of left fielder Carl Crawford, who hesitated before trying to make a diving catch. The ball bounced away from Crawford and Baxter barely beat his throw to second.
Tejada laid down a bunt to send Baxter to third. Dodgers third baseman Jerry Hairston caught Daniel Murphy's pop-up as he crashed into the railing in front of the Dodgers' dugout for the second out, but Wright laced the first pitch he saw from Brandon League into right-center field for an RBI single.
Wright was caught stealing on 1-0 pitch to Buck, though, to end the ninth.
Kemp's homer - his first of the season - was originally ruled a triple, but a replay showed that a security guard reached for the ball and touched it as the ball soared over the orange line in the right field corner.
Kemp, one year removed from one of the best Aprils in baseball history, finished 1-for-3 with a walk as he continued to work his way out of an early-season slump. He is hitting .429 (9-for-21) over the last five games after opening the season in a 10-for-55 slump.
Last April, Kemp won the NL Player of the Week award in each of the season's first two weeks and finished the month with a .417 average, 12 homers and 25 RBIs.
Wright's hit spared Mets phenom Matt Harvey his first loss of the season. Harvey allowed three runs on four hits and one walk with six strikeouts in six innings. Harvey hadn't allowed more than one run, nor thrown less than seven innings, in any of his first four starts.
Tejada had an RBI single and Justin Turner, pinch-hitting for Harvey in the sixth, had a sacrifice fly. Duda had two hits and reached base four times in five plate appearances.
Dodgers starter Ted Lilly, making his first big league appearance in 11 months, allowed one run on six hits and two walks with seven strikeouts in five innings and stranded seven baserunners, including five in scoring position.
The Mets tied the score in the fifth, when Harvey doubled off the wall in left field - and just missed a homer - and barely beat the throw to second for a leadoff double. Tejada followed with an RBI single that skipped just fair over the first base bag.
Murphy then singled, but Lilly struck out Wright, got Buck to hit into a fielder's choice and whiffed Davis to escape the threat.
The Dodgers opened the game by doing something nobody else has done this year: score a run off Harvey in the first. In a span of three pitches, Mark Ellis and Adrian Gonzalez singled and Kemp beat out the back end of a potential double play to bring home Ellis.
Lilly, making his first start since last May 23, allowed two singles and a walk in the second but wriggled out of the bases-loaded jam by retiring Harvey on a comebacker to the mound.
NOTES: Mets left-hander Jonathon Niese, who had to leave his start Tuesday in the third inning after he was hit on the right leg by an Ellis line drive, said Wednesday he still expects to make his next start Sunday but that he might push back his usual bullpen session from Thursday to Friday. ... Right-handed pitcher Shawn Marcum was in the locker room before the game and said he's looking forward to coming off the disabled list and making his Mets debut Saturday against the Phillies. Marcum has been sidelined by nerve inflammation in his neck and shoulder. ... Dodgers shortstop Hanley Ramirez, who tore a ligament in his right thumb during the World Baseball Classic on March 19, threw before the game. Manager Don Mattingly said Ramirez looked much better than the last time he threw in Baltimore last weekend. But while Ramirez expressed hope he could soon begin a three-game rehab stint and return to the Dodgers, Mattingly said he expected Ramirez would need more time in the minors before coming off the disabled list. ... Skip Schumaker replaced Crawford as the starter in left field and as the Dodgers' leadoff batter. Crawford entered Wednesday hitless in his last 14 at-bats. Crawford went 0-for-2 Wednesday as a late-inning replacement.
