Oklahoma City weathered the storm after Gilgeous-Alexander committed two quick fouls early in the third quarter, giving him four fouls for the game. The Thunder held their ground and even managed a 100-100 tie with Aaron Wiggins’ top shot 47 seconds before the end of the quarter.

Kenrich Williams’ jumper gave Oklahoma City a 34-25 lead early in the second quarter before Cleveland responded with an 8-0 run. The Thunder maintained the lead throughout the second before Allen converted an alley-oop.
