Kate Bennett scored her fourth goal of the season in the 20th minute for the Huskies, scoring with a shot from outside the box.
Freshman Havana McElvaine gave the Dawgs a 2-0 lead with her second goal of the season in the 50th minute, scoring on a free kick from midfield.
But the Wildcats clawed back, cutting the Huskies deficit to one with a goal in the 64th minute. The Wildcats completed the comeback with a goal off a throw in with just 16 seconds left, thwarting the Huskies of three points on the road.
Arizona outshot the Huskies 22-7, forcing Washington keeper Megan Kufeld to make five saves.
The Huskies moved to 7-6-4 on the season. Washington returns home to host Stanford on Thursday.
