Erik Spoelstra bemoaned Julius Randle's one-in-100 clutch three that defeated his Miami Heat and continued the New York Knicks' winning run.

The Knicks had won seven straight ahead of Friday's trip to the Heat but looked set to see that streak ended as they trailed by a point with only seconds remaining.

But Randle somehow worked room for a shot after initially fumble the ball on the right sideline and drained a stunning effort from three-point range.

Randle finished with 43 points and eight made threes, but it was understandably that final attempt that so frustrated Heat coach Spoelstra in a 122-120 defeat.

"If you did that play 100 times, 99 times out of that it's going to end up in our favour," Spoelstra said.

"That's just crazy unfortunate luck on our part and good fortune for them. He made a heck of a shot."

"Crazy" was how RJ Barrett described it, too, saying of Randle: "He just went crazy today.

"When you're in a mode like that and you're just making shots like that, the basket just gets bigger. We needed it, for sure."

Randle himself added: "It was fate. It felt good honestly when it left my hand. I was in the zone, I guess."

The forward so caught up in the moment he knocked Knicks coach Tom Thibodeau to the floor as he ran the length of the court to celebrate.

"He's a little mad at me right now," Randle joked later. "I need to talk to him."
