LOS ANGELES (AP) -TaJuan Porter and Aaron Brooks burned Arizona with their long-range shooting Thursday, combining for nine 3-pointers to help No. 16 Oregon beat the Wildcats 69-50 in the quarterfinals of the Pac-10 tournament.
Porter, a 5-foot-6 freshman, shot 8-of-12 - including 5-of-6 from 3-point range - for 21 points. Brooks, the Ducks' leading scorer, had all 16 of his points in the first 13 minutes to help put Oregon ahead for good. He shot 6-of-13, including 4-of-8 from outside the arc.
The fourth-seeded Ducks (24-7) have won five straight games.
The loss snapped a three-game winning streak for the Wildcats, who have won at least 20 games in 20 consecutive seasons but struggled at times while playing one of the nation's toughest schedules this year. Nevertheless, they're expected to be invited to their 23rd straight NCAA tournament.
Arizona (20-10) was seeded fifth - its lowest in the 10-year history of the Pac-10 tournament.
The teams split during the regular season, with Arizona winning at Oregon by two points and Oregon winning at Arizona by three. This game was anything but close as the Ducks beat the Wildcats for just the third time in the last 11 meetings.
Malik Hairston added nine points and 10 rebounds for the Ducks.
Three-pointers by Porter and Maarty Leunen gave Oregon a 46-31 lead before Arizona's Ivan Radenovic made his first two baskets of the game. But freshman Joevan Catron and Porter scored six points each during a 12-2 run that put the Ducks on top 58-37 with 9:41 remaining.
Williams scored five points around two free throws by Radenovic to cut Oregon's lead to 60-46 with 5 1/2 minutes left, but that's as close as the Wildcats would get.
Brooks made four 3-pointers in five attempts and added a pair of baskets from inside the arc as Oregon took a 24-16 lead in the opening 13 minutes. Hill scored five straight points to move Arizona within three, but the Ducks outscored the Wildcats 10-2 to finish the first half for a 34-23 lead.
Radenovic and Shakur, a pair of seniors averaging in double figures, were both scoreless at that stage, missing six shots between them.
Radenovic, coming off a career-high 37-point performance in the Wildcats' 85-80 overtime victory at Stanford, finished with six points, eight rebounds and six assists, and Shakur scored two. They combined to make only 3 of 13 shots.
