EL SEGUNDO, Calif. — The Los Angeles Lakers needed a win. Badly.

Thankfully for them, the Portland Trail Blazers were willing to help.

A get-right game was exactly what the Lakers received Sunday, a 107-98 victory over the mostly hapless Trail Blazers at Crypto.com Arena.

LeBron James and Austin Reaves didn’t play for the Lakers, and it didn’t even matter.

Anthony Davis scored 30 points, and D’Angelo Russell added a season-high 28 as the Lakers never fretted other than a sloppy stretch in the third quarter. Russell also compiled 14 assists, almost as many as the entire Portland team (17).

The win put a period on an otherwise calamitous week for the Lakers. They lost by 29 to Minnesota and then 41 in Miami to give them their worst two-game point differential (minus-70) in their 76-year existence.

Then they suffered a tough two-point setback in Atlanta that offered the added insult of going to overtime.

There were no such worries Sunday as the Lakers improved to 13-11 and held a team under 100 for the second time this season.

Not to be forgotten, Rui Hachimura scored 23 points and added four steals. He was a main reason the Lakers outscored Portland by 20 in the second quarter.

When word trickled out that James would sit because of foot soreness, Hachimura was asked to fill in some of the scoring punch.

“The coaches told me I had to step up tonight,” Hachimura told Spectrum SportsNet. “I just tried to be aggressive.”

The Lakers now get some down time. Lots of it, actually.

They play only two games over the next 10 days, allowing ample time for rest and even a few days of practice. Their next game isn’t until Friday at Minnesota.

“We’ve got to kind of reconnect,” Hachimura said. “Our first 10 games were kind of good. We’ve got to get back to what we were.”

Indeed, the Lakers had lost seven of their last nine before beating Portland (8-16).

There was even a feel-good story for the Lakers.

Undrafted rookie Quincy Olivari scored his first NBA basket, a three-pointer in the second quarter for the short-handed Lakers.

“A lot of prayer, a lot of preparation and a lot of perseverance,” Olivari said. “It meant a lot. It was a great feeling.”

Then he smiled.

“I hope it’s three points of 50,000,” he said. “I dream big.”

Why not? James is the NBA’s all-time scoring leader with 41,003 points and counting, but nobody would fault Oilvari on an overall breezy night for the Lakers.

In the end, the Lakers found the victory they needed. Seemingly everyone contributed.

“Rui in that second quarter was great and [Russell] was just having a big-time game,” Lakers coach JJ Redick said before adding the obvious. “A.D. was fantastic....It was overall a really good game for our group.”
