SEATTLE -- Lauri Markkanen had 26 points and 13 rebounds, Allonzo Trier scored a season-high 21 points and No. 5 Arizona held off a challenge from Washington for a 76-68 victory on Saturday night.

Arizona (25-3, 14-1 Pac-12) remained on top of the conference standings and won its fourth straight. The Wildcats did it short-handed, with starters Dusan Ristic and Kadeem Allen out because of injuries.

It wasn't easy, as Washington put forth one of its best efforts of the season but still couldn't snap a losing streak that's now reached nine games, tied for the longest in school history. Chance Comanche's rebound and dunk with 52 seconds left finally gave Arizona enough of a cushion to hold on in the final moments.

Markelle Fultz scored 26 points, but the Huskies (9-18, 2-13) had no field goals over the final 4:41 of the game.

Comanche finished with 12 points filling in for Ristic. Ristic was out after spraining his left ankle in Thursday's win over Washington State. Allen was considered a game-time decision after dislocating a finger on his shooting hand, but never left the Wildcats' bench.

Washington took its only lead at 52-51 as Fultz spun through the lane and converted a difficult layup with 14:50 remaining. Arizona coach Sean Miller called timeout and Arizona immediately went to a zone defence that stymied the Huskies. Meanwhile, Trier hit his fourth 3-pointer to put Arizona in front and dunks by Markkanen and Comanche pushed the lead to 60-53 with 10:40 remaining.

David Crisp's 3-pointer snapped a nearly five-minute drought without a field goal by Washington, but Markkanen scored four straight points to push the lead to 67-58 with 7:20 left.

The Huskies didn't go away. Fultz rattled in a 3-pointer with 4:37 left and Arizona's lead was down to 69-65. It was the final field goal for the Huskies as the Wildcats pulled away in the closing moments.
