Donovan Mitchell set a Cleveland record with 71 points, most by any player in 17 years, and the Cavaliers rallied from 21 down to beat the Chicago Bulls 145-134 in overtime.
Mitchell's total matched the eighth-highest in league history and marked the most points by an NBA player since Lakers great Kobe Bryant scored 81 against Toronto on Jan. 22, 2006. Wilt Chamberlain owns the NBA record with 100 for Philadelphia against New York on March 2, 1962, at Hershey, Pennsylvania.
Mitchell scored 13 points in the extra session after forcing OT by grabbing his own intentionally missed free throw and making a circus shot with three seconds left in regulation, tying the game at 130 and breaking the Cleveland record with 58 points.
In OT, Mitchell became the seventh player in the 70-point club. Chamberlain did it six times, while Bryant, David Thompson, Elgin Baylor, David Robinson and Devin Booker reached the figure once apiece.
Mitchell also had a career high-tying 11 assists and eight rebounds in 50 minutes. He set career bests with 20 free throws made and 25 attempted. He scored five points in the first quarter, 11 in the second, 24 in the third and 18 in the fourth.
Mitchell went 22 of 34 from the field and made 7 of 15 3-pointers in carrying the Cavaliers, who were without All-Star guard Darius Garland (right thumb sprain) and forward Evan Mobley (right ankle soreness) for the second straight game.
DeMar DeRozan scored 44 points, Zach LeVine had 26 points and Nikola Vucevic added 20 points and 13 rebounds for Chicago, which did not trail in regulation.
During his postgame news conference, Mitchell was almost in disbelief when it was mentioned he joined the list of NBA legends to surpass 70 points.
The Bulls visit Philadelphia on Wednesday night.
