LOS ANGELES -- The Los Angeles Dodgers waited all night for the big hit to come.

It took until one out was left in the game, but pinch hitter Trayce Thompson finally delivered with his first-ever walk-off hit, driving Hansel Robles' fastball into the left field bleachers for a walk-off home run to give the Dodgers a 3-2 win over the New York Mets on Tuesday at Dodger Stadium.

"I was just trying to keep it simple and trying to look for a heater or something simple and square it up," Thompson said. "It was a fastball over the plate that I was there to handle."

It was the Dodgers' first walk-off, pinch-hit home run since Scott Van Slyke hit an 11th-inning shot to beat the Arizona Diamondbacks on Sept. 10, 2013.

"It's special to get in here and celebrate with your teammates," Thompson said. "It's definitely a crazy feeling. It happened so fast, but I'm happy to help the team win."

Kenley Jansen (1-0) earned the win with one inning of scoreless relief.

Robles (0-2) retired two batters before serving up the Thompson home run.

Mets starter Jacob deGrom went seven innings and gave up two runs on eight hits. He struck out four without issuing a walk.

Dodgers starter Alex Wood continued to impress at home but did not factor into the decision, leaving the game still searching for his second win of the season. Wood gave up two runs (one earned) on four hits, struck out nine and walked two in 6 1/3 innings.

Wood is 4-2 with a 2.00 ERA in eight starts at Dodger Stadium, benefitting from a minor mechanical adjust made prior to his April 29 start against the San Diego Padres.

"I've felt pretty crisp the last three starts," Wood said. "I think it's just making everything really consistent across the board. I feel pretty good with all three of my pitches these last three starts. It was really big, to be honest, to figure out my timing and my consistency with everything."

The Dodgers got to deGrom early when Chase Utley and Corey Seager both doubled to open the first inning. Seager's double to center field scored Utley easily, and Gonzalez's fly ball to left field scored Seager to make it 2-0.

Mets manager Terry Collins said that deGrom is fighting through mechanical issues.

"This guy was in trouble for the first five innings but still gave us seven innings, and that tells me a lot," Collins said. "He's not where we know he can be. This guy is usually pinpoint, and he hasn't been that, and that's why he's been struggling. But I'll tell you one thing, I like running him out there every fifth day."

The Mets tied the game in the second inning when Wood failed to get the first two batters out and Utley threw away a routine grounder.

Cespedes singled up the middle to lead off, and Wilmer Flores reached on an infield single. Michael Conforto hit a grounder to Utley, who bobbled it, allowing Cespedes to score from second.

Kevin Plawecki continued his hot streak with an RBI single up the middle, scoring Flores and tying the game at 2-2.

New York center fielder Yoenis Cespedes kept the game tied in the fourth and fifth innings. Yasiel Puig hit a high fly ball to lead off the fourth inning, but Cespedes made a leaping catch at the wall for the out.

With two outs in the fifth, Adrian Gonzalez tried to keep the inning alive by stretching a two-out single into a double. Cespedes played the ball off the wall and gunned down Gonzalez with time to spare at second.
