Dallas Mavericks rookie Cooper Flagg made NBA history Friday night, scoring 51 points in a 138-127 home loss to the Orlando Magic. At just 19 years and 103 days old, Flagg became the youngest player ever to reach the 50-point milestone in a single game.

Flagg's historic performance came under unusual circumstances, with assistant coach Frank Vogel temporarily taking over after head coach Jason Kidd was ejected. The rookie briefly left the game with 45 points before returning to seal his achievement with a three-pointer and a conventional basket plus foul shot that brought the crowd to its feet. He finished with 24 points in the fourth quarter alone.

Shooting 19-of-30 from the field, including 6-of-9 from three-point range, and perfect from the free-throw line, Flagg joined an elite group as only the ninth rookie in NBA history to score 50 or more points. His performance matched the highest-scoring game by a rookie since Brandon Jennings dropped 55 points during the 2009-10 season, cementing Flagg's place among the league's most explosive young talents.
