SEATTLE (AP) – Chucky Jeffery scored 19 points, including a game-clinching uncontested layup with 59 seconds left, and 18th-ranked Colorado survived a frigid-shooting first half to beat Washington 70-59 in the quarterfinals of the Pacific-12 tournament Friday night.

The Buffaloes (25-5), the tournament’s No. 4 seed and winners of 10 straight, face top seed and No. 4-ranked Stanford in the semifinals on Saturday. The Cardinal (29-2) beat Colorado by 17 and 13 points during the regular season.

Jazmine Davis scored 17 points for the fifth-seeded Huskies, (20-11) who will have to hope for an at-large bid if it they are to play in their first NCAA tournament since 2007. Washington was hoping to ride the momentum of Thursday’s dramatic comeback from a 22-point deficit to beat Oregon 69-62 in the first round.

Jamee Swan added 15 points and 10 rebounds for Colorado, which pulled away after shooting 28 percent in the first half.
