Cleveland Cavaliers clinched sensational victory over the Chicago Bulls in an NBA clash.

The Cleveland Cavaliers has clinched a sensational come-back victory over the Chicago Bulls in an NBA clash. The Cavaliers rallied from 21 down to beat the Chicago Bulls 145-134 in overtime.

Cavaliers' star Donovan Mitchell has scored an NBA season-high and franchise-record 71 points, most by an NBA player in 17 years.

Mitchell's total matched the eighth highest in league history since Lakers legend Kobe Bryant had 81 points 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 3.0 seconds left, tying the game at 130-all and breaking the Cavaliers record with 58 points.
