Washington actually outscored Oregon in the second half, but this game between two hated rivals was over at halftime. Washington didn’t belong on the court with the Ducks in the first 20 minutes.

Oregon was up 48-13 at the halftime break, eventually winning it 84-56 to move to 12-6 on the season and 5-2 in conference play. The win—Oregon’s sixth in a row—helps the Ducks as they look to continue building a tournament résumé.

The Huskies (9-8, 4-3 Pac-12) were held to just four made shots in the first half. They had 14 turnovers and 13 points after the first 20 minutes. In part, Oregon was able to completely take the Huskies out of their offense.

They put up 43 second-half points, something UO coach Dana Altman will surely address with his team after, but still finished the game with six more turnovers (23) than made baskets (17).

Washington shot just 31% from the field and 20% (4-of-20) from beyond the 3-point line. The team’s leading scorer, Terrell Brown Jr. who came in averaging north of 21 points a night on 46% shooting, was limited to only 14 points on 3-of-16 shooting.

Will Richardson was the high man for the Ducks, putting in his fourth 20-point scoring effort of the year and the third in Oregon’s last five games. As the Ducks have gotten hot against the rest of the Pac-12, it has been Richardson firing them to wins more often than not. Over the Ducks’ six-game winning streak, Richardson is averaging 20 a game while shooting 58% from the floor and 53% from 3 (17-of-32).

Quincy Guerrier and Jacob Young each pitched in 12 points as well.

As a team, Oregon hit 50% of its 3s and 54% of its shots from the field while posting 16 assists against 13 turnovers.

As it built up its first-half lead, Oregon was surgical. It made eight of its 12 3-point attempts—Richardson had 13 first-half points to power the Ducks—and turned 14 Washington turnovers in 17 Oregon points the other way. On 15 shots inside the 3-point line, UW mustered only 10 points.

It was 13-6 and then, in a flash, it was 40-8. Oregon had a pair of dunks and dropped four triples over the course of a 27-2 run. During that span of roughly eight minutes, Washington missed eight straight shots and turned it over eight times.

And that was that.

Oregon is back in action on Tuesday against Colorado. Tip-off for that one is set for 7 p.m. PT.

The Huskies are off until Thursday when they’ll also play host to Colorado. Tip-off is set for 8 p.m. PT in the second and final matchup of the regular season between the two. CU took the first meeting 78-64.
