Facing the NBA’s top team and one of the league’s elite players, the Clippers needed to be at their best Sunday if they were going to extend their winning streak to six games.

But they failed to deliver in the final seconds against the Oklahoma City Thunder and Shai Gilgeous-Alexander, losing 103-101 in a tense battle at the Intuit Dome.

Derrick Jones Jr. made one of two free throws with 1:22 left, leaving the Clippers down 101-100 before things unraveled.

Two costly turnovers, including one by Ivica Zubac after he fumbled the ball out of bounds with 1:01 left, ended one chance to take the lead. Then, with 21 seconds left, Norman Powell missed a shot, and after Zubac got the offensive rebound, Kawhi Leonard missed a shot with four seconds remaining.

The loss dropped the Clippers to eighth in the West.

Gilgeous-Alexander, held to seven-for-29 shooting from the floor, finished with 26 points. He made all 11 of his free-throw attempts, including two in the final seconds.

Leonard had 25 points and 10 rebounds. James Harden, who finished with 17 points, moved past Moses Malone for 11th on the NBA’s all-time scoring list.

The Thunder, who swept the season series against the Clippers, have the NBA’s best record at 58-12 and the league’s leading scorer and most valuable player candidate in Gilgeous-Alexander (32.9 points per game).

It wasn’t all bad news for the Clippers — coach Tyronn Lue was back on the sideline. He missed five of the previous seven games because of back pain, with the Clippers going 6-1 over that stretch with assistant coach Brian Shaw at the helm.

Lue thanked his coaching staff for keeping the team in good shape.

“I feel a lot better,” Lue said. “I’m just going to take it day by day, game by game. … The pain from my shoulder and back kind of went down my leg a little bit. … I feel really good as far as my back and shoulder. Now, it’s just trying to get the leg part better, but I do feel better from that regard. That’s what was giving me the most problems.”
