De'Vion Harmon's game-high 17 points and a late, 13-3 run powered Oregon to a 68-63 win and a season sweep of No. 12 UCLA on Thursday in Eugene, Ore.

The Ducks (18-10, 11-6 Pac-12 Conference) came into Thursday's matchup having lost three of their previous four to complicate their NCAA Tournament at-large bid prospects. Oregon came out strong, leading for much of the first half.

The advantage grew to as many as 13 points when UCLA - playing the entire second half without Johnny Juzang - went on a 19-5 run to take a 54-53 lead.

Tyger Campbell paced the Bruins rally with 12 points, matching Cody Riley for a team-high.

But poor 3-point shooting contributed to UCLA's cold finish. The Bruins shot just 2-of-18 from beyond the arc in the second half and missed their first 14 attempts from deep in the period.

UCLA (20-6, 12-5) did not make a second-half 3-pointer until David Singleton's with 46 seconds remaining. Oregon was in firm command by that point, having taken a nine-point lead on its decisive run that spanned more than four minutes.

Jacob Young scored 14 points and dished one of his game-high six assists to Eric Williams Jr. on an alley-oop slam dunk that capped the Ducks' 13-3 burst. Williams finished with 11 points.

Will Richardson added another 11 points for Oregon despite shooting just 3-of-13 from the floor, including 1-of-7 beyond the 3-point arc.

UCLA finished 4-of-24 from deep, and no Bruin made more than one. Jaime Jaquez Jr. joined Campbell and Riley in double-figures scoring with 10 points, but fouled out ahead of the stretch run on an offensive foul.

Jaylen Clark, who scored a combined 59 points in UCLA's previous three games, was held to just five on Thursday. He attempted only one field goal in the second half while facing foul trouble.

Juzang finished with seven points in 11 minutes when his night was cut short before halftime with a right ankle injury.
