EUGENE, Ore. -- There was good news and bad news Friday afternoon for Oregon ace Cheridan Hawkins, though the bad news wasn't all that bad, and the good news was phenomenal. The junior left-hander threw her first career perfect game in an 8-0, five-inning shutout of No. 19 Washington at Howe Field, more than making up for a gaffe during a home run celebration that cost the No. 2 Ducks a run.

Koral Costa's three-run homer capped a five-run first inning for the Ducks (29-3, 7-0 Pac-12), and Hailey Decker ended the game with a walk-off, two-run blast in the fifth. Hawkins, meanwhile, shut the Huskies down, striking out three along the way in a 56-pitch effort.

The Ducks also scored in the fourth when, with one on and one out, Nikki Udria deposited a ball over the centerfield fence. In one of the more unique scoring decisions in Howe Field history, Udria was ruled out before crossing home because Hawkins -- leading the charge of Ducks to greet Udria at home plate -- crossed into fair territory too early. Hawkins steadied herself to retire the side in order in the fifth, however, and was able to laugh about the play afterward.

"Obviously I'm happy to throw a perfect game, but yeah, that's my roommate and she hits her first home run, and I'm a ding-dong and run across home plate -- jump actually,” Hawkins said. “I don't know what I was thinking. But I'm happy all around. We played a great game; 8-0 win, good defense -- what more can you ask for?"

Hawkins' perfect game was the first by a UO pitcher since Jess Moore dominated No. 17 Arizona in five innings on April 14, 2013. The day before Hawkins had thrown her first of what is now five career no-hitters.
