The 39-year-old scored 23 points in the Lakers’ 110-106 victory and also contributed nine rebounds, nine assists and three steals.
The Lakers go into the play-offs as the seventh seed and will face defending champions the Denver Nuggets in the first round.
Speaking to reporters, James said: “It was a good all-round team win. This was a long road trip, you almost forget we were in Memphis before these two games.
“Tonight was definitely a play-off game so get your mind right, get your body right, try to get as much recovery as we can before we have to go out there on Saturday.
“It’s a sprint now, we already went through the marathon. Tonight we showcased what we’re able to do both offensively and defensively. We’ve got a good group going right now, a good rotation, good plan and guys are coming in ready to go.”
James, who will compete in the play-offs for the 17th time in 21 seasons, feels his team have their work cut out against the Nuggets.
“It’s the defending champion, they know what it takes, they know how to win, they’ve been extremely dominant at home over the last few years,” he said.
“They’ve got high-level players, high IQ players, they’ve got a hell of a coach. We have to play mistake-free basketball and make it tough on them.”
D’Angelo Russell added 21 points with five 3-pointers and Anthony Davis had 20 points and 15 rebounds for the Lakers, who advanced to face the defending NBA champion Denver Nuggets in a rematch of last season's West finals.
Williamson shot 17 of 27 and had 11 rebounds and five assists in his postseason debut before he went to the locker room after tying the game at 95 on a driving layup with 3:19 remaining. He threw a towel to the floor in disgust as he walked into the tunnel with what coach Willie Green called “left leg soreness.”
Williamson didn’t get much help, as Brandon Ingram scored 11 points on 4-of-12 shooting and CJ McCollum was limited to nine on 4 of 15, including 1 of 9 from 3-point range.
Soon after Williamson’s injury, James hit a jumper, Davis dunked on an alley-oop, Russell drained a 3 and Davis grabbed a crucial offensive rebound, then hit two key free throws.
New Orleans will take on Sacramento on Friday for the final playoff spot in the West.
Kings roll to eliminate Warriors
Keegan Murray scored 32 points with eight 3-pointers and every Sacramento starter scored in double figures as the Kings cruised to a 118-94 victory to eliminate the Golden State Warriors and stay alive in the play-in tournament.
Harrison Barnes scored 17 points, Domantas Sabonis added 16, 12 rebounds and seven assists and Keon Ellis contributed 15 points as the Kings moved on to a matchup with New Orleans on Friday with a chance to return to the playoffs as the eighth seed in the Western Conference.
Golden State was kept out of the playoffs for the third time in five seasons, including two eliminations in the play-in tournament. The Warriors committed 16 turnovers, gave up 15 offensive rebounds and missed 23 of 33 from long range.
Stephen Curry had 22 points, but Klay Thompson didn’t score and missed all 10 shots from the field.
Julius Randle had 27 points and 10 rebounds and RJ Barrett added 26 points in his return from injury as the Knicks handed the star-studded Clippers their second straight defeat following a 3-1 start to the season.
Harden took the court for the first time since being traded to Los Angeles by the Philadelphia 76ers last week. The 10-time All-Star had 17 points on 6-of-9 shooting along with six assists as a part of a starting lineup that included three other accomplished veterans in Kawhi Leonard, Paul George and Russell Westbrook.
The dynamic guard scored five straight points late in the third quarter to give the Clippers a 76-73 lead, but the Knicks countered with a 16-3 run to take an 89-79 advantage with under 9 1/2 minutes left and never trailed thereafter.
Barrett scored 11 points in the fourth quarter after missing New York's previous two games with a sore left knee, while Mitchell Robinson finished with 13 points and 15 rebounds to help the Knicks snap a two-game losing streak.
Edwards sparks overtime win as Wolves hand Celtics first loss
Anthony Edwards scored eight of his 38 points in overtime as the Minnesota TImberwolves handed the Boston Celtics their first loss of the season with a 114-109 victory.
Edwards added nine rebounds and seven assists to help Minnesota overcome an off night from fellow star player Karl-Anthony Towns, who managed just seven points in 28 minutes before fouling out in overtime.
Jaden McDaniels hit a game-tying 3-pointer late in regulation and finished with 20 points for Minnesota, which also received 14 points and 12 rebounds from Rudy Gobert en route to its third straight win.
Boston entered the game as the NBA's lone remaining unbeaten team following a 5-0 start. The Celtics got 32 points and five steals from Jayson Tatum and 26 points from Jaylen Brown, but shot just 28.2 per cent from 3-point range as well as a season-low 39.1 per cent overall.
The Celtics held a 105-103 lead after Tatum hit two free throws with 3:56 left in overtime, but Minnesota's Mike Conley buried a 3-pointer on the ensuing possession before Edwards capped a pivotal 9-0 run with three consecutive baskets that put the Timberwolves up for good at 112-105 with 1:30 remaining in the extra session.
Adebayo's triple-double propels Heat past Lakers
Bam Adebayo delivered a massive performance with 22 points, 20 rebounds and 10 assists, and the Miami Heat overcame a late scoring drought to hold on for a 108-107 win over the Los Angeles Lakers.
Adebayo became the first Heat player to record a triple-double with at least 20 rebounds, and Miami received 28 points from Jimmy Butler and 22 from Tyler Herro to record its second straight win following a four-game losing streak.
The Heat prevailed despite nearly blowing a 10-point lead with four minutes to play and not making a field goal over the final 4:15 of the contest.
The Lakers scored the game's final nine points and had a chance to win in the final seconds, but Cam Reddish was off the mark with a jumper and Butler grabbed the rebound right before time expired.
LeBron James finished with 30 points on 13-of-23 points to pace the Lakers, while Austin Reaves just missed a triple-double after compiling 23 points, 10 rebounds and nine assists.
Los Angeles has now dropped the first two outings of its current four-game road trip and played the entire fourth quarter without star forward Anthony Davis, who sustained a groin spasm during the game and was limited to nine points in 25 minutes.
Williamson starred in his NBA postseason debut Tuesday, scoring 40 points while adding 11 rebounds and five assists in over 36 minutes of action against the Los Angeles Lakers.
The two-time All-Star, though, missed the final three minutes of New Orleans’ 110-106 loss after injuring his left hamstring.
Williamson tied the game at 95 with 3:19 remaining in the fourth quarter on a driving layup, but he left shortly after and headed to the Pelicans’ locker room.
His huge performance caught the attention of Lakers superstar LeBron James.
“He's a generational player, a generational talent. He's going to continue to get better and better,” James said. “Tonight was just a small microcosm of how great he can be, his ability to get downhill, finish vs. smalls, finish vs. bigs, taller guys, shorter guys, doesn't matter.
“One thing about him, he's not afraid to compete. So, that's a great thing. He's a star.”
Williamson missed plenty of time due to various injuries in his first four seasons after New Orleans selected him No. 1 overall in the 2019 NBA Draft, but he was healthy throughout the 2023-24 campaign.
Williamson appeared in a career-high 70 contests and led the Pelicans with 22.9 points per game while averaging 5.8 rebounds and 5.0 assists.
The winner of Friday’s matchup between New Orleans and Sacramento will capture the No. 8 seed in the West and move on to play the top-seeded Oklahoma City Thunder in the first round of the playoffs.
