EL SEGUDNO, Calif. — A new item rocketed toward the top of the Lakers’ fix-it list — their success (or lack of it) in the second game of a back-to-back situation.

NBA observers wouldn’t be overly surprised to hear the Lakers lost Wednesday in Miami, 112-98, after appearing to reclaim momentum a day earlier with a victory in Orlando.

The Lakers had their chances despite a slew of turnovers, but they just are not great when forced to play two games in as many days, falling to 1-4 on the second night in a season-long testimony to their lack of depth.

Unfortunately for the Lakers, they have six more back-to-backs this season.

Stuck at 13 in the Western Conference, the Lakers fell to 2-5 since losing Anthony Davis to a stress injury in his right foot. He might not return until at least mid-January, according to a report in The Athletic, so the Lakers (14-21) need to figure out more ways to win without him.

A couple of notable categories didn’t go the Lakers’ way. They had way more turnovers than the Heat, 26-6, which led to many, many more points off turnovers for Miami (31) than the Lakers (two).

“I thought that was extremely detrimental to us trying to compete,” Lakers Coach Darvin Ham said. “I’ve been saying it all season. Those self-inflicted wounds that we have to clean up, they come back and rear their ugly heads.”

LeBron James had 27 points, but six turnovers negated his six assists. It was his last game before turning 38 years old on Friday.

The Lakers got plenty of contributions from their supporting cast Tuesday in Orlando but couldn’t make the same claim in Miami.

Lonnie Walker IV was scoreless for the first time with the Lakers and Austin Reaves also failed to score a point. They combined to miss eight 3-point shots.

Reaves and Dennis Schroder had far more turnovers (eight) than assists (three) when adding their stats together, underscoring the Lakers’ problems with ball security.

If there was a Lakers bright spot, it was the return of reserve forward Juan Toscano-Anderson.

He missed almost a month with a severely sprained ankle but brought his typical energy in the second half and kept alive three possessions because of offensive rebounds.

“It was great to have him out there with his activity,” James said.

Jimmy Butler scored 27 points and Bam Adebayo added 23 points and 14 rebounds for Miami (18-17). Miami held a 95-78 lead through three quarters before the Lakers finally showed some defensive chops. It was too late.

“When your anchor is out, Anthony Davis, that puts a little pressure on your defense,” Lakers guard Pat Beverley said. “At times, we do show [good defense]… and when we don’t, we lose.”

The Lakers have two more games on this trip — at Atlanta and Charlotte — before returning home next week for a rematch against Miami.
