SEATTLE, Wash. -- Taylor McQuillin was one out away from her second one-hit shutout of a top-five team this season, before Sis Bates tied the game with a single in the bottom of the seventh, and Julia DePonte won the game with walkoff homer an inning later, leading top-ranked Washington over No. 9 Arizona in game 1 of the top-10 showdown in Seattle, 2-1 in eight innings.

In a game that featured 22 combined strikeouts to just five total hits, Washington's Taran Alvelo (14-1) outdueled McQuillin (16-2) in a matchup between two of the nation's top pitchers facing two of the nation's top offenses. Alvelo allowed one run on two hits with 14 strikeouts while McQuillin allowed two runs on three hits with eight strikeouts. 

The two dominated the first five innings of the game. There was only one hit entering the sixth, a bloop single by Washington's Kelly Burdick. Then, in the sixth, Alyssa Palomino broke up Alvelo's no-hit bid with a one-out homer. It looked like it was going to be enough support for McQuillin, until, with two out in the bottom of the seventh, Bates recorded the second Washington hit of the game to score Burdick, who was hit by a pitch to start the half inning, to tie the game. The Huskies (30-2, 2-2 Pac-12) walked off in the eighth on DePonte's homer.

The loss is the first of the conference season for UA. The Cats fall to 24-4, 3-1 Pac-12 on the year. They will try to even the series on Saturday at 3:30 p.m. MST.

McQuillin retired the first eight Huskies of the game before a two-out bloop single started a two-out rally for the Dawgs. A hit batsmen and a walk loaded the bases, but McQuillin fanned the Pac-12's home run leader, Kirstyn Thomas, for the second time to get out of the inning and leave the bases loaded.

Arizona was held without a hit until the top of the sixth. With one out, Palomino broke up Alvelo's no-hit bid with a solo homer to left to give the Cats a 1-0 lead. The home run was her ninth of the season and extended her career-long hitting streak to 12 games, the longest by a Wildcat this season.

In the bottom of the seventh, a leadoff HBP came around to bite McQuillin. A two-out walk moved the tying run into scoring position, which would come into score on Washington's second hit of the game.

DePonte led off the bottom of the eighth with a homer to win the game.

Up next: Arizona and Washington continue the series on Saturday at 3:30 p.m. MST for game 2 on the Pac-12 Networks.
