Donovan Mitchell scored an NBA season high and club-record 71 points as Cleveland Cavaliers rallied from 21 down to beat Chicago Bulls 145-134 in overtime.

It was the eighth-highest individual tally in history and the largest since Lakers legend Kobe Bryant scored 81 points against Toronto in 2006.

Mitchell scored 13 points in the extra session after forcing overtime in Cleveland by grabbing his own intentionally missed free throw and making a circus-shot with three seconds left.

The former Utah Jazz standout drained a triple to begin overtime to claim Cleveland’s point-scoring record and give them their first lead.

Wilt Chamberlain owns the NBA record with 100 points for Philadelphia against New York in 1962.

“I’ve never been witness to a performance like that live,” Cavs coach JB Bickerstaff said.

“We were treated tonight to one of the greatest performances in the history of the NBA.”

Mitchell also had an equal career-high 11 assists and eight rebounds in 50 minutes, also setting personal bests with 20 free throws made and 25 free throws attempted.

DeMar DeRozan scored 44 points, Zach LeVine had 26 and Nikola Vucevic added 20 points and 13 rebounds for Chicago.

Meanwhile, Klay Thompson scored 54 points, but it was Kevon Looney’s put-back off his miss that was the difference as Golden State beat Atlanta 143-141 in double overtime in San Francisco.

Trae Young finished with 30 points, 14 assists and seven rebounds for the Hawks, but shot at just 36 per cent.

A hamstring injury was all that could stop Zion Williamson’s dominance of Philadelphia, the 76ers running away 120-111 winners after the New Orleans star was hobbled.

Joel Embiid had 42 points and 11 rebounds on his home court, James Harden scored 27 and Williamson scored 26 points on 10-of-12 shooting through three quarters before he left for the locker room.

There was no immediate word on whether Williamson would miss any coming games.

Without Williamson, the Pelicans couldn’t keep up with the 76ers, with Embiid’s eighth game this season of at least 35 points and 10 rebounds earning him “MVP! MVP!” chants from the stands.

Australian Ben Simmons had nine assists, six rebounds, four points and three steals to be plus-22 for the Nets in 23 minutes of court time.
