BOSTON (AP)Donovan Mitchell and Caris LeVert each scored 41 points and the Cleveland Cavaliers rallied to beat the Boston Celtics 132-123 in overtime on Friday night.

Cleveland trailed by as many as 15 in the first half and overcame a 75-point first half by the Celtics to earn its fourth straight win.

It was LeVert’s best game since joining the Cavs at the trade deadline last season, when he never figured out his role because of injuries. His previous high for Cleveland was 32 points last season against Dallas.

Jayson Tatum and Jaylen Brown led Boston with 32 points apiece. The Celtics shot 51% against the NBA’s second-rated defense, but also had 19 turnovers.

Cleveland scored the first five points in OT. Boston rallied and tied it back up on a steal and dunk by Brown.

The Cavs led 126-123 when LeVert corralled an errant pass by Tatum, was fouled and hit two ensuring free throws.

Brown missed on the other end LeVert calmly drained a 24-footer with 31 seconds to play.

Boston built a 15-point lead before shooting 9 of 20 and committing six turnovers in the third quarter as their lead was trimmed to 99-95 entering the fourth.

Cleveland stayed close throughout the period and took a 113-112 lead on a corner 3-pointer by LeVert with 1:10 to play.

The Celtics turned it over on a traveling call on Marcus Smart but got it back following a missed jumper by Mitchell. It started a fast break and led to layup by Brown with 28 seconds left.

Jarrett Allen was fouled underneath but connected only 1 of his 2 free throws. Tatum then missed 3 at the end of regulation.

The Cavaliers remained without All-Star Darius Garland, who continues to recover from the left eye laceration he sustained in their season opener. It left the point guard duties to Mitchell, who still managed to keep up his scoring with 17 points in the opening 24 minutes.

Mitchell also had the play of the night, stretching for a one-handed dunk over 7-footer Luke Kornet in the third quarter and then briefly staring down the big man before trotting back down the floor.
