Phoenix Suns coach Jeff Hornacek has labelled Gerald Green "unstoppable" following his performance against the Toronto Raptors on Sunday night.

Green was in impressive form, having come off the bench to score 28 points and lead his side to a 121-113 victory at the Air Canada Centre.

"Gerald was back. He had a couple of bad games recently, coinciding with Eric [Bledsoe] coming back and kind of changed his role," Hornacek told reporters after the game.

"But he came in yesterday to practice worked on his shots and he told us all he was back and it was a mini vacation. When he plays like that, he gets unstoppable."

The victory sees the Suns sitting in third position in the Pacific division, with a record of 38-28 for the season.
