Norman Powell scored 23 points, OG Anunoby added 21 and the Toronto Raptors recovered in the second half after blowing a 21-point lead to beat the Miami Heat 101-81 on Friday night.

Pascal Siakam had 15 points and 14 rebounds for the Raptors, who never trailed on their way to avenging a loss to the Heat on Wednesday night.

Kendrick Nunn led the Heat (6-8) with 20 points, but the injury-riddled defending Eastern Conference champions made just seven of 31 3-point shots (22.7%) in losing for the fourth time in six games. Bam Adebayo had 14 points and eight rebounds.

The Raptors (6-9) led 34-13 when Powell's layup completed an 18-2 run with 2:52 left in the first quarter. They were 8 of 11 on 3-point shots in the period.

Powell, starting in place of the injured Kyle Lowry, scored 19 points in the first half.

Goran Dragic had two layups and a baseline jumper and Gabe Vincent added three layups in a 19-5 Miami run that opened the second half and tied it at 61.
