Dusan Ristic scored 18 points, Lauri Markkanen added 11 and No. 17 Arizona wore down Utah for a 66-56 victory Thursday night.
Arizona (14-2, 3-0 Pac-12) had offensive lapses at times, but used its size advantage to get the Utes into foul trouble and prevent them from getting many open looks on the perimeter.
The Wildcats held Utah (10-4, 1-1) to a long scoreless drought in the first half and 4-of-21 shooting from 3-point range overall to win their 14th straight home game.
Parker Jackson-Cartwright had nine assists while controlling Arizona's offense much of the night in his third game back from a sprained ankle.
David Collette scored 13 points despite battling foul trouble most of the game and Devon Daniels added 12 for the Utes.
Ristic, who was playing after his grandfather passed away earlier that day, was 7-10 shooting and had 8 rebounds to go with his 18 points.
