Kirk Nieuwenhuis had another game to remember.

Almost two weeks to the day after becoming the first Met to hit three home runs in a home game, Nieuwenhuis was perfect at the plate Saturday night.

The centerfielder went 4-for-4 with a walk, four RBIs and two runs in the Mets' 15-2 win over the Dodgers.

"I made a few adjustments mechanically [going in], but I think the biggest thing was just playing a little bit more loose and with a little more confidence," said Nieuwenhuis, who lifted his average to .196. "Just kind of going out there and playing the game."

Nieuwenhuis batted seventh and gave Juan Lagares a rare night off in centerfield. Lagares has started 87 games, including 11 of the previous 12. Nieuwenhuis started in center for the fifth time. Lagares pinch hit for Curtis Granderson in the seventh.

"I think the last few outings, especially the last one against [Clayton] Kershaw was tough," Nieuwenhuis said. "We're playing a stretch of games here where it's not going to be easy for us. This one win was just as important as all the 162 others that we look to get."

His two-run single to left-center drove in Daniel Murphy and Kelly Johnson to cap a four-run first. Nieuwenhuis' RBI single to center in the third gave the Mets a 5-0 lead.

Michael Conforto scored on Nieuwenhuis' double in the fifth to make it 7-1. Nieuwenhuis then scored on Matt Harvey's double.

Not a bad first three at-bats for Nieuwenhuis, who hit those three home runs in his first three at-bats in the Mets' 5-3 win over the Diamondbacks on July 12.

"This is a good reminder that baseball is a crazy game," he said. "You can't get too caught up in some of these tough stretches."

The Mets finished with a season-high 21 hits and 15 runs. Harvey, who improved to 9-7, was 2-for-4 with two RBIs. He got the win after allowing six hits and two earned runs in seven innings, striking out four and walking one.

"It was a nice four-spot in the first. I was happy at that point," Harvey said. "Obviously, I've struggled early in the game the last couple of outings. For me to go and get us back in the dugout as quick as I could in the first and then putting up runs like that was great. The run support definitely helped."

Manager Terry Collins said the recent additions of Johnson and Juan Uribe helped bring some energy to the clubhouse. Johnson started at second and had two hits and two runs scored. Uribe came off the bench to spell Murphy at third and singled to center in the eighth.

"We're glad they are here," Collins said. "We're going to obviously mix and match to try and keep them in the lineup and we'll see if our offense picks up."
