Shai Gilgeous-Alexander scored a career-high 54 points to lead the Oklahoma City Thunder to a 123-114 home win over the Utah Jazz on Wednesday.

Neither team led by double digits until the Thunder pulled away in the last 3 1/2 minutes.

Jalen Williams finished off a three-point play to break a tie at 106-106 with just more than five minutes remaining, kicking off a closing 17-8 run.

Gilgeous-Alexander helped break the game open, coming up with the rebound on his own missed 3-pointer, then making a 3-pointer to put Oklahoma City ahead by nine with 3:32 remaining.

After he hit a pair of free throws put the Thunder ahead by 11, their biggest lead of the game, Gilgeous-Alexander hit a fadeaway jumper in the lane for his first career 50-point game.

Gilgeous-Alexander’s previous career high was 45, accomplished twice earlier this season. He attempted a career-high 35 shots, making 17, and also went 17 of 18 from the free-throw line.

Gilgeous-Alexander also had eight rebounds, five steals, three steals and two blocks.

Williams, who missed Sunday night’s win over Brooklyn with a strained right hip, had 25 points with his parents in the stands wearing split Oklahoma City-Utah jerseys.

Williams’ brother, Cody, plays for the Jazz but missed the game with a sprained left ankle.

After a bit of a slow start, Gilgeous-Alexander surged late in the first, scoring 15 points in the quarter. But the Thunder were just 2 of 10 from beyond the arc in the opening quarter.

Oklahoma City led by nine with just more than five minutes remaining in the second quarter before the Jazz ripped off a 15-6 run to tie the game.
