TORONTO (AP) — Pascal Siakam had 23 points and 11 rebounds before fouling out, O.G. Anunoby scored 10 of his 18 points in the fourth quarter and the Toronto Raptors beat the Cleveland Cavaliers 108-105 Wednesday night.

Gary Trent Jr. scored 19 points, and Scottie Barnes and Fred Van Vleet each had 15 as Toronto outscored Cleveland 32-21 in the final period.

Donovan Mitchell scored 31 points in his Cleveland debut, Jarrett Allen had 13 points and 10 rebounds, and Evan Mobley added 14 points for the Cavaliers, who held an eight-point lead through three quarters but failed to close it out.

Cleveland All-Star guard Darius Garland injured his left eye in a collision with Trent late in the second quarter and didn't return. Garland shot 2 for 8 and scored four points in 13 minutes.

Cedi Osman scored 17 points and Mitchell had nine assists for the Cavaliers, who are hoping to take a step forward this season after acquiring him from Utah over the summer. Cleveland reached the play-in tournament last spring, but was eliminated after losing in Brooklyn and at home to Atlanta.

Toronto shot 8 for 22 from 3–point range through the first three quarters, but made 5 of 8 from long distance in the fourth.

The Cavaliers led 97-92 with 4:55 left in the fourth before Barnes scored and Anunoby made a pair of free throws that cut the deficit to one.

After Allen turned the ball over, Anunoby fed Barnes for a driving dunk that put Toronto up 98-97 with 3:31 left.

Cleveland led 57-51 at the half. Mitchell scored 10 points in the third as the Cavs took an 84-76 lead to the fourth.
