here,” Betts said. “We’ve just got to keep playing. It’s a long season. I know you can say it’s a long season, you can say it for a long time. But it is. In the grand scheme of things, it is a long season and you just got to get hot at some point.”

Max Muncy has gotten hot over the past two weeks since bringing back a “step-back” move to trigger his swing.

Muncy hit his 11th home run of the season Sunday, giving him the major league lead over Pete Alonso (10) for now. Eight of Muncy’s home runs have come in the past 11 games since he made that adjustment — four in the four-game series at Wrigley Field. He is 11 for 34 since then with 12 RBI.

Muncy’s 11th home run of the season didn’t come until August last year.

“He’s been on one of his, maybe his best tear in this 10-day, two-week period, whatever it is,” Dodgers manager Dave Roberts said. “He was lost early, and now you’re talking about leading the league in homers. ... Having some of the guys not swinging well, to have Max carry us, big cog.”

The Dodgers have done enough things wrong over the first month of the season to muddle along within a game of .500 for most of that time.

But there’s one thing they have really done right — hit home runs.

Betts, Muncy and J.D. Martinez each cleared the ivy at Wrigley Field on Sunday and the Dodgers lead the National League with 43 home runs. Only the Tampa Bay Rays have hit more (48).

“It’s huge,” Betts said of the importance of the Dodgers’ ability to hit home runs to an inconsistent offense. “Obviously you don’t want to live and die by it. But right now it’s helping us stay afloat. I don’t know if we’re out there trying to hit homers, but they’re going over the fence. So we’ll take them as we can get them.”

Betts turned the Dodgers’ power on with a two-run home run in the third inning. That tied the score after the Cubs had scored two unearned runs in the first inning against Dodgers starter Clayton Kershaw, set up when Muncy couldn’t handle Nico Hoerner’s grounder to his backhand.

Kershaw gave up a solo home run to Yan Gomes in the fifth inning to put the Cubs back on top. But Muncy and Martinez gave the Dodgers the lead for good when they hit back-to-back home runs in the sixth inning.

Given a lead, Kershaw made it hold up. But he had some help from Wrigley Field’s geometry.

The walls in right and left field curve in sharply at one point, creating a “well” where the wall moves 5 feet closer to home plate. Kershaw got fly balls to the deep part of the “well” in left field — by Eric Hosmer in the fourth inning and Patrick Wisdom in the sixth. Each time David Peralta was standing on the warning track when they came down, harmless fly outs that would have landed in the bleachers had they been hit 10 feet to the right.

“It wasn’t pretty today — a lot of lineouts, a lot of balls at the track caught,” said Kershaw who allowed just one unearned run in six innings.

“It wasn’t great all around. I didn’t have a great feel for — didn’t have great command in general today. You’re going to have days like that. You just try to make the best of it. The guys picked me up.”

Betts handled three plays at shortstop smoothly before a pop up in no-man’s land drew him, Muncy and Peralta together for a moment of danger. The ball fell in as Peralta made a diving attempt and Betts danced out of harm’s way.

“It looked right. I thought he looked comfortable, confident,” said Dodgers manager Dave Roberts, acknowledging that he “held his breath” on the bloop double.

“The more you see him, the more he amazes you. Special athlete.”

Betts added a two-run double in the ninth inning before Brusdar Graterol escaped a bases-loaded situation in the bottom of the ninth — with Betts starting a game-ending double play from shortstop.

“It was fun,” Betts said. “We won, so that’s the most important thing.”
