Donovan Mitchell scored 29 points and the Cleveland Cavaliers defeated the New Orleans Pelicans 131-122 on Wednesday night to open 9-0 for the first time in their 55-year NBA history.

Caris LeVert and Jarrett Allen each added 16 points, and Allen grabbed 14 rebounds as the Cavaliers surpassed an 8-0 start by the 1976-77 squad that finished 43-39 under coach Bill Fitch.

Zion Williamson returned from a two-game absence and had 29 points for the Pelicans. He temporarily took himself out after playing 10 minutes but returned to start the second half and scored 23 after halftime.

Jose Alvarado hit all seven 3-pointers he took and finished with 27 points for New Orleans. Brandon Ingram added 20 points for the Pelicans, who have lost three straight and six of seven.

Cleveland had no trouble rallying back from an early 12-point deficit on the road and did so in part by shooting 54.2% overall, including 48.6% from 3-point range.

After Alvarado's back-to-back 3s made it 112-106, Mitchell responded with a hesitation move in the lane and a floater to make it 114-106 and stem the Pelicans' momentum with 5:20 left.

Cleveland got 50 points from reserves, led by LeVert and Ty Jerome (11 points).

Rookie Risacher has best game to lift Hawks

Surging Suns rally past Heat

Kevin Durant scored 32 points, Jusuf Nurkic had 20 and 18 rebounds, and the Phoenix Suns rallied from a 15-point deficit for a 115-112 victory over the Miami Heat to extend their winning streak to six games.

The Suns trailed 79-64 in the third quarter but finished the period on a 15-3 run to cut the Heat’s lead to three.

Neither team could take control in the fourth, but Durant’s jumper from the free-throw line with 16 seconds to play gave Phoenix a four-point lead.

Devin Booker had 22 points and nine assists for Phoenix (7-1), which has won its last five games by six points or fewer. Booker made one of two free throws with 4.8 seconds to go, giving the Heat a chance, but Miami failed to get a shot off before time expired.

Grayson Allen scored 12 points and Tyus Jones matched Booker with nine assists for the Suns.

Tyler Herro led the Heat with 28 points. Reserve forward Haywood Highsmith scored 19 and Jimmy Butler added 15. Bam Adebayo had 12 points and 12 rebounds.

The Suns’ 7-1 start matches the best in franchise history, equalling three previous seasons (1980-81, 2000-01, 2009-10).
