LAKE BUENA VISTA, Florida－While the ultimate objective is to win a title, LeBron James said the Los Angeles Lakers achieved a key goal against the Portland Trail Blazers－and it wasn't simply to win the first-round playoff series.

It was improvement.

"We got better throughout the course of the series," James said. "We knew we were coming into a series versus a hot Portland team that was playing the best basketball inside the bubble along with Phoenix. So we wanted to just come in and try to work our game, get better and better as the games went on, as the series went on. And I believe we did that."

James had 36 points, 10 rebounds and 10 assists and the Lakers advanced to the Western Conference semifinals, beating the shorthanded Blazers 131-122 in Game 5 on Saturday night.

Anthony Davis had a playoff-best 43 points for the top-seeded Lakers in their first playoff appearance since 2013. The Lakers hadn't won a playoff series since 2012.

James has never lost a first-round playoff series, going 14-0.

The Lakers will play the winner of the series between Houston and Oklahoma City. The Rockets took a 3-2 lead with a 114-80 victory earlier on Saturday.

CJ McCollum had 36 points for the surprisingly scrappy Trail Blazers, who played without injured All-Star guard Damian Lillard. Carmelo Anthony added 27 points.

Down 14 in the third quarter, Portland got to 100-97 on McCollum's layup and tied it on Anfernee Simon's 3-pointer to cap an eight-point run with 9:46 left. James answered with a 3.

Gary Trent Jr.'s 3-pointer tied it at 109 with just under seven minutes to go. Again the Lakers held off Portland with Kentavious Caldwell-Pope's 3.

After Trent's 3-pointer closed it to 114-112 with 4:53 left, Davis had a personal 11-0 run to put Los Angeles up 123-112 and all but seal it.

The game was originally set for Wednesday night, but players collectively decided not to play in the three playoff games scheduled for that day to protest racial injustice following the police shooting of Jacob Blake in Kenosha, Wisconsin. Games on Friday were also postponed.

James said he hopes the past few days made a difference.

"Obviously, the bubble season will never be forgotten. In sports this is the first time we've been able to do something like this, but this moment is so much bigger than us playing basketball," James said. "Hopefully, years on down the line, when America is in a better place, you can look back to this moment and be like, that was one of the catapults that kind of got it going."

Lillard injured his right knee in Game 4, prompting him to leave the bubble in Florida and return to Portland to see team doctors. Lillard was named MVP of the seeding games heading into the playoffs, averaging 37.6 points and 9.6 assists in eight games.

Trent Jr. took Lillard's spot in the opening lineup. However, because of injuries the eighth-seeded Blazers had just nine players available for the game.

"All you can do is hope to hang around and make it a fourth-quarter game and win in the end, and we didnt quite win it in the end," Blazers coach Terry Stotts said.

Portland's lone win in the first-round series came in Game 1.

Tip-ins

Trail Blazers: In addition to Lillard, Portland was without Zach Collins because of left-ankle inflammation, Nassir Little with dehydration and Wenyen Gabriel with right-quad tendonitis.

Lakers: Rajon Rondo practiced on Friday but remained inactive for Game 5 as he recovers from a fractured right thumb and back spasms. Dion Waiters was a game-time decision with a migraine but was available.

Civic duty

The Lakers announced before the game than that Staples Center will serve as a voting center for the upcoming US general election. Voters can cast ballots at the arena from Oct 30 through Nov 3. The arena will also serve as a drop-off site for ballots.
