With Arizona's No. 1 ranking hanging precariously in the balance, T.J. McConnell hustled over to the corner for the biggest offensive rebound of the game.
Then Nick Johnson drew a foul, and the Wildcats overtook Michigan at the free throw line.
Johnson made six free throws over the final 25 seconds, and Arizona held on for a 72-70 victory over the Wolverines on Saturday after rallying from an 11-point deficit in the second half.
Michigan led by one with under a minute to go, but McConnell was able to rebound his own miss to keep a crucial possession alive.
Johnson drew a foul on a drive with 24.6 seconds left, and he put the Wildcats ahead to stay.
"This was as quality of a win as you can have, in my opinion, in the country," Arizona coach Sean Miller said. "I felt like today — we're going to be better if we won, we're going to be better if we lost."
No. 13 Kansas 80, New Mexico 63: Perry Ellis scored 21 points, Joel Embiid added a career-high 18 and No. 13 Kansas pulled away in the second half to beat New Mexico at home and end a frustrating two-game skid. Andrew Wiggins, who dealt with foul trouble much of the night, added 11 points for the Jayhawks (7-3), who led 39-38 at halftime but used two big runs over the final 20 minutes to blow it open.
No. 12 Wichita St. 70, Tennessee 61: Tekele Cotton scored all 19 of his points in the second half and No. 12 Wichita State beat Tennessee as the host Shockers (10-0) got off to the best start in school history.

Georgia 84, Lipscomb 75: Brandon Morris scored a career-high 17 points in his first start at point guard, leading Georgia over visiting Lipscomb (4-6). Charles Mann, the starting point guard and Georgia's (4-4) leading scorer, watched from the sidelines with a sore knee as Morris and walk-on Taylor Echols handled the minutes at the point. Echols had played a total of 37 minutes previously in his Georgia career and had never scored. He had nine points Saturday.
Mississippi 72, MTSU 63: Jarvis Summers scored 25 points, Marshall Henderson added 15 and Mississippi rallied for over Middle Tennessee State at home. Ole Miss (7-2) took a 61-60 lead on Henderson's three-pointer with 5:33 remaining and never trailed again.

Martin Methodist 79, Georgetown 74: Martin Methodist College (8-3) used a 21-6 surge in the final 20 minutes to top visiting Georgetown (9-2). Georgetown trailed by only two at the break, but the second-half surge was too much to overcome. The Tigers got as close as one, 73-72, on a pair of free throws by Noah Cottrill, but Martin Methodist finished on a 6-2 run to seal the game. Bopper Stenzel kept Georgetown close in the first half with all 10 of his points off the bench.
No. 7 Louisville 108, Austin Peay 53: Shoni Schimmel scored 24 points, Cortnee Walton had 13 and No. 7 Louisville's high-powered offense was too much for visiting Austin Peay. Sara Hammond added 12 points to help Louisville (10-1) win its third straight game. Ranked sixth nationally in field goal shooting at 49 percent, the Cardinals shot 52 percent against the Lady Govs.
Transylvania 65, Defiance 59: Senior guard Madisen Webb netted 28 points in the Pioneers' win over host Defiance. Webb went 6-for-13 from the floor and 12-for-12 from the charity stripe, also notching two steals and an assist in the season-high game. The Pioneer's intense defensive pressure forced Defiance to give up 25 turnovers.

Cheyenne Madden and Kelah Eldridge backed up Conley with 14 and 12 points, respectively. Berea was paced by Johnesha Warren with a game-high 20 points.
Cumberlands 67, Union 54: Poor shooting did Union in as it fell to Cumberlands in the Union Holiday Classic. The Bulldogs (8-5) made only 18 of 55 shots (32.7 percent) against Cumberlands (4-3) and was 2-for-17 (11.8 percent) from long range.
Florida's Walker cleared on academics
No. 19 Florida could have highly touted freshman Chris Walker in the rotation soon.
Walker, a McDonald's All-American, has been admitted to school and was scheduled to practice Saturday.
Coach Billy Donovan already has ruled him out for Tuesday's game against No. 16 Memphis.
But Walker eventually will help the Gators this season.
Vandy's Dahlman out
Vanderbilt women's basketball player Rebekah Dahlman will be sidelined indefinitely after having surgery and a follow-up procedure to remove a blood clot.
Dahlman, a freshman guard from Braham, Minn., has started all nine games this season and is averaging 11.4. She leads the Southeastern Conference in three-point percentage at 51.4 percent.
