Gabbie Plain dominated for the second straight day, and Washington defeated Oregon 6-2 on Friday in the Women's College World Series.
Plain, a freshman from Australia, gave up four hits and no earned runs in six innings against the top-seeded Ducks. She gave up just four hits in 5 2/3 shutout innings on Thursday against two-time defending champion Oklahoma. Fifth-seeded Washington (51-8) needs one win Sunday to advance to the championship series.
Oregon (53-9) won all three meetings against its Pac-12 rival during the regular season.
Washington loaded the bases with one out in the fifth. Kelly Burdick put the ball in play and forced a throw home. Washington's Kaija Gibson scored, despite taking a glove to the face on the tag attempt. Taylor Van Zee then singled and knocked in two runs to chase starter Megan Kleist. Washington scored four runs in the inning to take control for good.
The tournament is a two-bracket, double elimination system, with the national championship held June 4-6.
