SEATTLE — Friday’s first half was about as bad as it has been for the Oregon State women’s basketball team in quite some time.

The Beavers managed to make just five field goals and scored a mere 13 points in the first two quarters at Washington State.

It was the complete opposite against Washington on Sunday.

The No. 16 Beavers blitzed the Huskies for 35 first-quarter points — and set a program record with 18 made 3-pointers — in cruising to a 95-57 Pac-12 win to earn a weekend sweep of the Washington schools.

Couple that with Arizona State being swept on the road at the Los Angeles schools, and the Beavers hold a two-game lead over the Sun Devils and California for the No. 4 seed in the Pac-12 Tournament with four games to play.

Oregon State (19-6, 10-4), two games back of three teams tied for first place, returns home to take on No. 8 UCLA (21-4, 12-2) Friday night at Gill Coliseum. The Huskies (7-18, 1-13) head to Colorado on Friday.

The Beavers had six scorers finish in double figures, led by Kat Tudor’s 23 points. Mikayla Pivec added 15, Taya Corosdale 13, Katie McWilliams 11, and Taylor Kalmer and Aleah Goodman had 10 each.

The Beavers also tied the Pac-12 record with the 18 made 3-pointers.

“This team, when the ball moves like that and the passes are good, that ball tends to go in a lot,” OSU coach Scott Reuck said in his postgame radio interview.
