Former Utah forward Pelle Larsson scored a career-high 27 points against his former team as Arizona outlasted Utah, 105-99, in three overtimes.
The Wildcats led by 16 at halftime but the Utes tied the game in the final minute of regulation with a Ryan Madsen three-pointer. Kylan Boswell, who left had earlier left the game with a shoulder injury, missed a shot at the end of regulation that would have won it for Arizona.
The Wildcats scored nine straight points in the third overtime, sparked by a Caleb Love three-pointer. It was the Utes first home loss of the season.
Arizona, ranked 8th in the country, improves to 18-5 (9-3) and will visit Colorado on Saturday night.
