SEATTLE—Somewhere in the middle of a mosh pit at midcourt, Dominic Green, the unlikeliest of heroes, exchanged embraces with just about everyone who ran on the court.

The Washington students tried to carry him off the court and who could blame them since he lifted the Huskies to their biggest win in more than a decade.

It was Green’s three-point dagger at the buzzer that downed No. 9 Arizona and gave Washington an amazing 78-75 victory Saturday night in a sold out Alaska Airlines Arena.

Green, a three-point specialist who is shooting over 53 percent behind the arc against Pac-12 teams, finished with 14 points while connecting on 4 of 5 from downtown.

On the final possession, the Huskies went inside to forward Noah Dickerson, who danced around Arizona’s 7-footers for a game-high 25 points.

However, this time 7-foot-3 freshman center Deandre Ayton, a projected top-three pick in this year’s NBA draft, emphatically swatted Dickerson’s attempt.

Green recovered the ball and rose up over an Arizona defender for a three-pointer that buried into the bottom of the net.

David Crisp added 16 points and Jaylen Nowell had 14 for the Huskies, who improved to 17-6 and remained in third place in the Pac-12 at 7-3.

The win snapped UW’s eight-game losing streak to Arizona.

The Wildcats (19-5, 9-2), who entered the game with seven straight wins, received 21 points from center Dusan Ristic. Allonzo Trier had 20 and Ayton 19.

In addition to an incredible finish, this game had it all.

It began with the emotional return of Lorenzo Romar, the Arizona associate head coach who spent the past 15 years guiding the UW team, with a long and warm reception before the game.

Romar exchanged long embraces with each member of the UW staff, particularly with Cameron Dollar, his former assistant, and UW head coach Mike Hopkins.

The Huskies never trailed in the first half and stymied an Arizona offense that entered the game averaging 82.5 points.

Washington held the Wildcats to 36.4 percent shooting and their second-fewest points in the first half while taking a 35-28 lead into the locker room at the break.

The last time UW fans stormed the court was March 7, 2009, when the Huskies won their first outright conference title in 53 years.
