Victor Wembanyama has amassed 28 points, 10 rebounds and three blocks as the San Antonio Spurs sent the NBA's Western Conference finals back to Oklahoma City for a deciding Game 7, routing the Thunder 118-91.
Game 7 is Saturday night, with the winner hosting the New York Knicks on Wednesday night to open the NBA Finals.
Wembanyama and the Spurs responded to a listless 127-114 loss in Game 5 on Tuesday with their most energised outing of this see-saw series in San Antonio on Thursday night.
Dylan Harper had 18 points, Stephon Castle added 17 and Devin Vassell had 12 points and two thunderous blocks for San Antonio as they levelled the series at 3-3.
NBA MVP Shai Gilgeous-Alexander was limited to a team-high 15 points on 6-for-18 shooting for defending champions Oklahoma City.
