WASHINGTON (AFP) — Oklahoma City stretched the National Basketball Association’s best win streak to 13 games with a home victory Thursday while the reigning champion Boston Celtics held on for a last-shot win at Minnesota.

Shai Gilgeous-Alexander had game highs of 29 points and eight assists to spark the Thunder over the Los Angeles Clippers 116-98 at Oklahoma City, improving the Western Conference leaders to 28-5.

The Thunder’s win streak is the longest since the team relocated from Seattle after the 2007-08 season.

“It’s just being present, going day by day, working on ourselves and I think we’re doing a good job on that,” said Isaiah Hartenstein, who added 11 points, nine rebounds and six assists for the Thunder.

Oklahoma City trailed 52-48 at half-time but outscored the Clippers 42-20 in the third quarter and Los Angeles never closed the gap.

“We wanted to come out and just pick up the pressure,” Hartenstein said. “We weren’t playing the way we wanted, with the force we wanted. We wanted to pressure them and I think we did a good job of that.”

At Minneapolis, the Celtics were without Jaylen Brown due to a right shoulder strain and Kristaps Porzingis with an ankle sprain but won for the third time in four games to start a difficult road trip, dispatching the Timberwolves 118-115.

Jayson Tatum sparked Boston with 33 points on 13-of-27 shooting, 6-of-17 from 3-point range, and added eight rebounds and nine assists.
