SEATTLE - Sydney Wiese scored 26 points and No. 6 Oregon State rolled into the Pac-12 Tournament semifinals with a 65-49 win over California on Friday.

Wiese and the Beavers (28-3) won their sixth straight, leading by as many as 16 in the first half and holding off every run by the Golden Bears. It was Oregon State's second win in a week over California, knocking off the Bears in the regular-season finale by 15.

Mikayla Pivec added 17 points for Oregon State, the top seed in the conference tournament. The Beavers won their first Pac-12 Tournament title a year ago, the precursor to a run to the Final Four. They will face No. 15 UCLA or Arizona State in Saturday's semifinals.

Kristine Anigwe led California (19-13) with 26 points. The Bears likely needed one more victory to bolster their NCAA Tournament hopes.
