BOSTON >> Shai Gilgeous-Alexander scored 34 and Chet Holmgren had 23 points and 15 rebounds on Wednesday night to lead the Oklahoma City Thunder to a 118-112 victory over the Boston Celtics in a much-anticipated potential NBA Finals preview.

The Western Conference-leading Thunder withstood a barrage of Boston 3-pointers — a franchise record 63 attempts in all — to sweep the defending NBA champions in the two-game season series and win for the 17th time in their last 18 games.

Jayson Tatum scored 33 for Boston, which had won five straight and 15 of its last 18 games. Al Horford added 18 points and 10 rebounds, and Derrick White scored 22.

Oklahoma City scored the first nine points of the game and led by 12 midway through the third before Boston tied it 88-all on Tatum’s three-point play to end the quarter. It was 98-98 in the fourth before the Thunder ran off eight straight points to pull away.

Clippers 119, Heat 104 >> Bogdan Bogdanovic scored a season-high 30 points and Ivica Zubac added 26 points and 14 rebounds, helping Los Angeles beat Miami.

James Harden had 24 points, 11 assists and eight rebounds for the Clippers, who won for the fourth time in five games and pulled within 1 1/2 games of idle Golden State for the No. 6 — and last guaranteed — playoff spot in the Western Conference.

Tyler Herro scored 31 points and Andrew Wiggins added 22 for the Heat, who fell 2 1/2 games behind Atlanta in the race for the No. 7 spot and most advantageous play-in position in the Eastern Conference.

The Clippers were again without coach Tyronn Lue, who has missed three straight games while dealing with back pain. Assistant coach Brian Shaw again served as acting coach.

Spurs 126, Mavericks 116 >> De’Aaron Fox had 32 points, 11 assists and nine rebounds and San Antonio snapped a three-game skid, beating injury-depleted Dallas.

Dallas (33-34) remained 10th in the Western Conference, holding the final spot for the play-in tournament by 2 1/2 games over Phoenix.

Fox was 12 for 25 from the field in his highest-scoring game since joining San Antonio in a trade with Sacramento on Feb. 5.

Keldon Johnson and Jeremy Sochan each had 18 points off the bench for San Antonio. Devin Vassell added 16.

Brandon Williams returned from a one-game absence to lead Dallas with 19 points. Dante Exum added 17 and Naji Marshall and Kessler Edwards had 15 each.

The Mavericks beat the Spurs 133-129 on Monday to snap a five-game skid.

Dallas only had nine active players Wednesday as the team remains without Kyrie Irving and Anthony Davis among others.

The Mavericks closed the first quarter on a 19-4 run in taking a 28-20 lead. Dallas extended the lead to 11 points in the second quarter while shooting 60% from the field.

San Antonio had eight turnovers in the opening quarter but only 16 for the game.

Grizzlies 122, Jazz 115 >> Luke Kennard scored 30 points and Ja Morant had 28, helping Memphis top Utah.

Kennard went 7 for 9 from 3-point range, and Morant was 4 for 7 from deep. Desmond Bane added 17 points as Memphis posted its fourth straight win.

Utah lost its seventh consecutive game. Collin Sexton had 22 points, eight rebounds and seven assists, and John Collins also scored 22 points.

Sexton scored to give the Jazz a 115-114 lead with 1:16 left, but Kennard responded with a 3 for the Grizzlies. Morant then hit another 3 to make it 120-115 with 12 seconds remaining.

Rockets 111, Suns 104 >> Jalen Green had 29 points to lead Houston to victory over Phoenix in a game where Houston’s Steven Adams and Phoenix’s Mason Plumlee were ejected for fighting.

Alperen Sengun scored 20 points and Dillon Brooks added 19 to help the Rockets extend their winning streak to four.

Bradley Beal’s two free throws got the Suns within eight with about 9 1/2 minutes to go before Houston used a 9-2 run to make it 99-84 with about seven minutes remaining. Jock Landale opened the run with a 3-point play and Brooks capped it with a layup after a turnover by Devin Booker.

Hawks 123, Hornets 110 >> Trae Young made all of his 21 free throws and scored 35 points to lead Atlanta to its fourth straight victory.

Young added 12 assists on a poor shooting night from the field. He was 7 of 20 and missed all five of his 3-point attempts.

Raptors 118, 76ers 105 >> AJ Lawson scored 28 points, Jared Rhoden set career highs with 25 points and 12 rebounds and Toronto beat Philadelphia in a matchup of short-handed teams.

Orlando Robinson scored a career-high 25 points and matched his career high with 12 rebounds to help the Raptors win for the fifth time in six games.

Andre Drummond returned after sitting out Monday night in a loss at Atlanta due to illness but the 76ers were without eight players including Joel Embiid (left knee), leading scorer Tyrese Maxey (back/finger), Paul George (left groin) and former Raptors star Kyle Lowry (right hip).

Toronto’s list of nine absentees included Scottie Barnes (right hand), leading scorer RJ Barrett (personal) and Immanuel Quickley (rest).
