EUGENE, Ore. (AP) Elgin Cook matched his career high with 26 points and Chris Boucher had 16 points and nine rebounds to lead Oregon to an 89-81 victory over No. 21 Southern California on Thursday night.

Dwayne Benjamin also had 16 points off the bench for the Ducks (15-4, 4-2), who moved into a tie for second place in the Pac-12 with their 18th consecutive home win. Oregon held the Trojans (15-4, 4-2), the conference's best 3-point shooting team, to 8 of 28 (28.6 percent) from long range.
