OKLAHOMA CITY — Shai Gilgeous-Alexander scored 28 points, and the Oklahoma City Thunder matched the best 25-game start to an NBA season by dominating the Phoenix Suns 138-89 in an NBA Cup quarterfinal on Wednesday.

The Thunder’s 24-1 mark ties the 2015-16 Golden State Warriors, who won their first 24 games before finally losing.

Chet Holmgren added 24 points and eight rebounds for the Thunder, who set a franchise record with their 16th straight win. They advanced to the semifinals on Saturday against the Los Angeles Lakers or San Antonio.

Phoenix guard Grayson Allen was ejected after he shoved Holmgren and knocked him to the floor.

The Thunder led 94-58 with 5:18 left in the third quarter when the two collided while Holmgren appeared to be setting a screen. Allen extended both arms, knocking Holmgren to the floor, and was called for a Flagrant 2.

Mavs star done

DALLAS — Dallas Mavericks center Dereck Lively II is set for season-ending surgery on his ailing right foot, another setback for the promising but oft-injured player.

The team said Wednesday the surgery will be performed by Dr. James Calder in London. The Mavericks previously said Lively was seeking multiple medical opinions as discomfort in the foot lingered.

He had a procedure on the same foot in the offseason. Lively’s final game of the season was a 118-115 victory over New Orleans on Nov. 21. He then sat the second night of a back-to-back after missing 10 of the previous 14 games because of a knee injury. The foot issue arose after his return.

The 21-year-old Lively will have missed 148 of a possible 246 games by the end of his third season.

Lively missed 27 games as a rookie, but was healthy for the postseason as the Mavericks made their first trip to the NBA Finals since winning the franchise’s only championship in 2011. Dallas lost to Boston in five games.

Injuries sidelined Lively for 46 games last season, and the former Duke standout and 2023 first-round pick will end up missing 75 games in 2024-25.
