The missed freebie allowed Phoenix to assume a one-point lead on their next trip down the floor, on two P.J. Tucker free throws.
But the 21-year-old wouldn't let his miss at the charity stripe sink Minnesota's chances at a W. With 6.3 seconds remaining, Timberwolves head coach Tom Thibodeau drew up a play to get Wiggins into a one-on-one matchup on the wing.
After a fairly thorough mugging from the defending Tucker, Wiggins ripped past his man, regained his balance, and drained a stepback jumper at the buzzer for a 112-111 victory.
Then he celebrated with his friends.
"I wasn't going to let no one stop me," Wiggins said.
The play was designed to spring multiple options.
"But my mind was made up once I got the ball. I was going to shoot it," Wiggins said. "I got to my spot. I knew the pull-up would be there."
Wiggins led all scorers with 31 points on 11-of-22 shooting, to go with six rebounds, three assists, and two steals. The victory is Minnesota's third in a row, and sixth in their last eight games.
"He got through that and got the shot off," Thibodeau said of Wiggins. "He got to his spot, which is part of the design of that play, to get to his spot. He had the concentration and the mental toughness to take all the stuff that happened on that play and make the shot. It was a great play by him."
The Timberwolves hadn't won on a buzzer-beater since Brad Miller was still in the league. Luke Ridnour hit a crazy floater with zero seconds on the clock in a February 22, 2012, victory over the Utah Jazz.
