SEATTLE -- Lia Galdeira had a career-high 34 points Thursday and Washington State advanced in the Pac-12 tournament's opening game, 66-64 over Oregon.
Galdiera was 6 of 10 from 3-point range and 14 of 24 overall with six rebounds and four assists for the Cougars (17-13).
Drea Toler stole Galdiera's pass and took all the way for a layup, pulling Oregon (13-17) within 66-64 with 1:04 left.
Washington State failed to score and Toler missed a layup for the Ducks with nine seconds left. Galdiera missed the front end of a 1-and-1, and Oregon's Lexi Peterson banked in a 3-pointer after the buzzer, too late to count.
Washington State will face second-seeded and No. 9-ranked Arizona State in the quarterfinals on Friday.
Jillian Alleyne had 18 points and 18 rebounds to lead the Ducks. She became the fourth player in NCAA history to record 450-plus rebounds in back-to-back seasons.
Galdeira's set the team's Pac-12 tournament record for points scored in a single game and ended three behind Oregon assistant coach Nicole Powell, who set the all-time mark (37) while she played for Stanford in 2002.
