The Pacific-12 Conference women's basketball tournament opened Thursday at KeyArena in Seattle, and both the Washington State Cougars and Washington Huskies advanced.

Lia Galdeira scored 17 points, Dawnyelle Awa added 10 and the Cougars beat Arizona State, 48-41.

Galdeira was 7-for-15 from the floor for eighth-seeded Washington State (11-19), which moves on to face No. 1 seed and fourth-ranked Stanford on Friday.

Janae Fulcher led the No. 9 seed Sun Devils (13-18) with 20 points. Promise Amukamara grabbed 14 rebounds but was just 1 of 12 shooting, part of a 29 percent team effort for ASU.

The fifth-seeded Huskies (20-10) held off the No. 12-seed Oregon Ducks (4-27). Washington will face No. 4 seed Colorado in round two.

The Sun Devils led 18-13 at halftime, but the Cougars rallied in the second half, going ahead for good, 29-27, on Sage Romberg's jumper with 14:58 left and building on the lead from there.

Washington State coach June Daugherty missed the game with acute appendicitis. The school said Daugherty was having surgery Thursday evening and was expected to be discharged Friday morning.
