Oklahoma City recovered from 29 points down to beat Memphis 114-108 in Game 3 and take a 3-0 series lead.
The comeback was the second largest in an NBA playoff game since detailed play-by-play records began in 1996-97.
Memphis dominates the first half
The Grizzlies built a 67-40 lead before Ja Morant left with a hip injury following contact from Luguentz Dort.
Morant attempted two free throws but did not return after half-time. He finished with 15 points and later rejoined the bench on crutches.
Memphis led by 26 at the break after making 27 of 47 shots.
Holmgren sparks the comeback
Chet Holmgren entered half-time with one point, then scored 16 in the third quarter and hit four three-pointers.
Oklahoma City’s defence changed the game. Memphis shot 9 of 36 after the break and committed 13 second-half turnovers.
Alex Caruso made all four of his steals after half-time, while the Thunder steadily removed a lead that had looked decisive.
Thunder move ahead in the final minutes
Jalen Williams made a free throw with 1:20 left to give Oklahoma City its first lead. He scored 26 points.
Shai Gilgeous-Alexander led the Thunder with 31 points and eight assists. Holmgren finished with 24 and eight rebounds.
Scotty Pippen Jr. scored 28 for Memphis and Jaren Jackson Jr. added 22, but the Grizzlies could not stop the collapse. Oklahoma City moved within one victory of a sweep.
