Layshia Clarendon scored 14 points and No. 6 California won its school-record 12th straight game with a 77-55 victory over Oregon on Friday night.
Afure Jemerigbe added 13 points for the Bears (24-2, 14-1 Pac-12), who early on looked somewhat ragged offensively without starting point guard Brittany Boyd, who sat out with a strained groin.
Cal started pulling away with a 12-2 run to close the first half en route to matching the record win streak set by the 2008-09 team. The Bears can break the mark against Oregon State on Sunday.
Jordan Loera and Ariel Thomas scored nine points each to lead the Ducks (4-23, 2-13).
