"I thought we showed really good resilience there," Thunder coach Mark Daigneault said. "The first thing we weathered was right out of halftime, (the Grizzlies’ lead) went to 12 and got a little dicey. We just played through it, got a couple of stops. Turned the game a little bit and got it back under control."

Ja Morant had 22 points and seven assists for Memphis, which lost for the third time in four games. Dillon Brooks scored 19 points, and Jonas Valančiūnas had 16 points and 14 rebounds.

The Grizzlies opened a 102-90 lead on Justise Winslow’s driving layup early in the fourth quarter. But the Thunder responded with a 14-2 run. Williams tied it at 104 with a cutting layup with 8:38 left.

Pokusevski’s 25-footer put Oklahoma City in front at 109-108 with 6:10 left. Darius Miller added another 3 to push the Thunder ahead by four on their next possession.

The Grizzlies never recovered, allowing 38 fourth-quarter points.

"We give them a lot of credit, I thought the Thunder played great today," Grizzlies coach Taylor Jenkins said. "We couldn’t get in a rhythm, I felt, offensively. We put them on the free-throw line too much. ... They got hot, you gotta give them credit."

AHEAD OF HIS TIME

The 19-year-old Pokusevski, who made five 3-pointers, became the second-youngest player in NBA history to make five-or-more 3s in a single game. He trails LeBron James, who achieved the mark in 2003.

The 7-foot Pokusevski also grabbed 10 rebounds in his third game since he was called up from his G-League assignment with the Oklahoma City Blue.

"Now he knows what a game like tonight feels like, which gives him confidence," Daigneault said.

"So, the next time he takes a step back, which he will, it’s part of development and it’s a part of competition, he’ll know that he can turn a corner. I think when you repeat that process and you keep getting those experiences, that’s where consistency and confidence come from."
