"There's two ways you can go: You can either try to rethink everything or you can just say 'Screw it,' and come back tomorrow and act like it didn't happen," Kershaw said. "So I'm going to go with the latter for now, I think."
Bellinger became the fastest player to reach 21 home runs in major league history, doing so in 51 games and breaking the mark of 20 homers in the same number of games by New York Yankees catcher Gary Sanchez (2015-16) and Boston Braves outfielder Wally Berger (1930).
"Guy was at second base, so I was just trying to get an RBI. Luckily, it went out of there," Bellinger said of his first-inning homer off Mets starter Zack Wheeler, who also yielded another one in the second. "The second one, I think it was 3-2, so I was trying to protect. I think it was inside, so I was just trying to protect."
Kershaw (10-2) served up all four home runs, a career high for him. The 17 home runs Kershaw has given up this season is a career worst, topping the 16 he allowed in 2012. Kershaw struck out 10 and walked one but allowed six runs and six hits in 6 1/3 innings against the Mets.
Mets starter Zack Wheeler (3-5) was tagged for seven runs and eight hits in two innings. It was the second worst outing for Wheeler, coming on the heels of Tuesday's 14-3 loss to the Chicago Cubs when he gave up a career-worst eight runs in 1 2/3 innings.
"Well, when you've got that kind of stuff and you're getting hit like he's getting hit, there's something," Mets manager Terry Collins said. "We've got to get to the bottom of it."
Wheeler said his command failed him again.
"It's really frustrating," Wheeler said. "But it all starts with me."
Turner, who extended his hitting streak to 14 games, had an RBI single in the sixth to increase the Dodgers' lead to 8-4.
However, Reyes took Kershaw deep again in the seventh with a two-run homer to close the gap to 8-6.
But Taylor's solo home run in the bottom of the inning and a run-scoring single by Chase Utley put the Dodgers up 10-6.
Bellinger's three-run blast highlighted a four-run surge by the Dodgers in the first. Turner had an RBI single in the inning for a 4-0 edge.
In the second, Turner smacked a two-run shot to left for a 6-0 advantage. Bellinger followed with his second homer, a solo shot to right center to make it 7-0.
Reyes launched his fifth home run of the season in the third, jumping on Kershaw's first pitch of the inning and hitting it out to left to cut the Dodgers' lead to six runs.
Bruce added a solo shot in the fourth to slice the margin to 7-2. It was his 19th home run this season.
Cecchini delivered a two-run shot in the fifth to pull the Mets within 7-4.
