DeMar DeRozan did not "think too much" as he sealed a last-second victory for the Chicago Bulls against the New York Knicks on Friday.

After RJ Barrett had put the Knicks three ahead with under 30 seconds remaining at Madison Square Garden, Zach LaVine pulled it back to one, before Jalen Brunson missed two free-throws at the other end.

That gave DeRozan the chance to win it, which he did with a jumper from just inside the arc in the final second of the contest as Chicago left New York with a 118-117 victory.

"You don't think too much about it," DeRozan said, having hit just eight of his 20 field-goal attempts prior to that moment. 

"You just read the way they're playing you. It's second nature. I don't care how many shots I missed before. That's a brand-new opportunity and you approach it that way."

On the Knicks' profligacy from the free-throw line on the night, where they missed 11 of 26 attempts, DeRozan added: "I'm glad they missed. The bad luck we've had all season of things not going our way, some went our way tonight and we capitalised on it."

Barrett was the star performer for the Knicks, albeit in defeat, as he ended the game with 44 points, and coach Tom Thibodeau said it was the other end of the court where his team struggled.

"It wasn't any one particular play. I just felt like we never really got our defense established and it was an offensive game," Thibodeau said.

"It's hard to slow those guys down once they get their confidence going like they did. We missed some free throws. Things can change real fast in this league."
