Shai Gilgeous-Alexander produced a stunning performance as the Oklahoma City Thunder beat the Minnesota Timberwolves to move within one win of the NBA Finals.
Oklahoma led 65-57 at the break and 90-85 at the end of the third quarter, but had to survive a late Minnesota fightback to take a 3-1 lead in the seven-game series.
Gilgeous-Alexander - who scored 40 points, grabbed nine rebounds and provided 10 assists - made five of six free throw attempts in the final 15 seconds to seal a 128-126 victory.
Jalen Williams added 34 points on 13-for-24 shooting, while Chet Holmgren finished with 21 points on nine-for-14 shooting.
The performance of Mark Daigneault's side was an impressive response to the 143-101 thrashing they suffered in game three.
Timberwolves pushed Oklahoma City all the way, with Nickeil Alexander-Walker scoring 23 points off the bench, Jaden McDaniels contributing 22 points, and Donte DiVincenzo finishing with 21.
Victory in game five in Oklahoma on Wednesday will secure the Thunder a place in the NBA Finals for the first time since 2012, where they would face either the Indiana Pacers or the New York Knicks.
