Early in the third quarter against the Pacers, Gilgeous-Alexander tried to drive to the basket but stepped on Justin Holiday's foot.
Rookie guard Josh Giddey added 19 points for the Thunder, who jumped on a weary Nets team to snap a five-game losing streak.
Giddey acknowledged that the milestone was "cool" after the game, however, made it clear that he would have preferred to walk away with a win.
