Shai Gilgeous-Alexander scored a playoff career-high 42 points to lift the Oklahoma City Thunder to a 121-109 road win over the Phoenix Suns on Saturday.
The reigning Most Valuable Player finished 15 of 18 from the floor with eight assists to give the Thunder a commanding 3-0 lead in their first-round Western Conference playoff series.
Oklahoma City has won 11 consecutive first-round games.
Gilgeous-Alexander’s previous playoff high was 40 points in Game 4 of last season’s Western Conference Finals against Minnesota.
Playing without Jalen Williams, who suffered a hamstring strain in Wednesday’s Game 2 victory, the Thunder leaned even more heavily on Gilgeous-Alexander.
Gilgeous-Alexander hit his first 11 shots, not missing until less than three minutes remaining in the third quarter.
Despite being without Williams, which moved Ajay Mitchell into the starting lineup, and Isaiah Joe, who was out for personal reasons, the Thunder reserves still dominated their counterparts. Oklahoma City’s bench outscored Phoenix’s 36-12.
The Suns were within nine early in the fourth quarter when Gilgeous-Alexander checked back in.
Moments later, Cason Wallace stepped into a passing lane, intercepting Devin Booker’s pass and fed to Gilgeous-Alexander for a layup on the other end, sending the Oklahoma City bench into celebration while Phoenix called a timeout with the Thunder up 13.
Gilgeous-Alexander finished 14 of 15 from inside the arc and 11 of 12 from the free-throw line.
Mitchell scored 15 points while Alex Caruso scored 13 off the bench.
Dillon Brooks scored nine consecutive Phoenix points to help his team pull within 10 with three minutes remaining.
The Thunder took a nine-point lead into halftime with a 12-2 run to close the second quarter.
Brooks led the Suns with 33 points while Jalen Green added 26 points. Booker scored just 16 points.
Grayson Allen, who had missed the last five games with a hamstring injury, made his first appearance of the postseason, playing 17 minutes and scoring seven points on 2-of-8 shooting.
The Suns were without Jordan Goodwin, who suffered a calf injury in Game 1, and Mark Williams (foot).
The Thunder have a chance to close out the series Monday in Phoenix.
