He backpedaled slowly, almost expressionless, after ball hit twine. Teammates Dakari Johnson and Julius Randle chased him down.
"Making that shot and seeing my teammates so happy and turning toward me, it's the best feeling in the world," Harrison said.
Michigan's Nik Stauskas missed a desperation heave at the buzzer and then, it was Harrison's turn on the bottom of a dog pile. Make that a puppy pile. Eighth-seeded Kentucky is the first all-freshman starting lineup to make the Final Four since the Fab Five at Michigan in 1992.
The Wildcats (28-10) will play Wisconsin next Saturday outside of Dallas at AT&T Stadium.
"They made a great shot," said Stauskas, who led the second-seeded Wolverines with 24 points. "I thought we did a pretty good job contesting it. It's part of basketball."
The Wolverines (28-9) ended their season one win shy of a second straight Final Four.
What a ride this has been for this group of Wildcats, who were touted as the team that could go 40-0, then dismissed out of hand when the bad losses piled up in January and February.
Coach John Calipari got things turned around by March, and for the second straight game in the Midwest Regional, Harrison made the shot that gave the Wildcats the lead for good. On Friday, he made the key 3 in Kentucky's 74-69 win over Louisville.
This time, he took a handoff from his twin brother, Andrew, in the corner and dribbled three times to the top left of the arc. He was standing a good three feet behind the line when he elevated over Caris LeVert and took a bit of contact on the hand from the Michigan guard as he shot. No matter. The ball rattled in.
Aaron Harrison scored 12 points off four 3-pointers over the last 8:05 and was Calipari's obvious choice to take the game-winner.
"I've been around guys who make these kind of plays," Calipari said. "I've always said, 'You cannot be afraid to miss.' He's not afraid to miss."
