EUGENE, Ore. (AP) DJ Davis scored 24 points, hitting six 3-pointers, as UC Irvine stunned No. 21 Oregon 69-56 on Friday night.
Dawson Baker added 11 points for UC Irvine (2-0), which is picked to finish fourth in the Big West Conference this season. The Anteaters made 12-of-28 3-pointers.
''Credit the guys in our locker room, they believed they could come in and compete and it is hard to generate that all the time, but we have a winning tradition,'' UC Irvine coach Russell Turner said. ''They had some guys out and it is not easy to play us early in the year, I know that. Give them credit for taking this game, it was a big deal for us to get an opportunity to come in here and play. This was a hell of an opportunity for us to play a team of their quality. We don't take this for granted.''
The Ducks were led by N'Faly Dante with 20 points while Nate Bittle added 10. Oregon shot 32.7% from the field, including 4-for-21 on 3-pointers.
''We got beat in every facet of the game,'' Oregon coach Dana Altman said. ''Hustle, toughness, a number of our practices resembled that and I was fearful that at some point in time that might come. They were the aggressor from the start.''
It was UC Irvine's first win over a ranked opponent since beating No. 18 Kansas State 70-64 in the 2019 NCAA Tournament. The last time the Anteaters beat a ranked team in the regular season was over No. 20 Stanford in 2003.
''It is meaningful, unquestionably, to beat a program of this quality and players of this quality in an arena where they have such an unbelievable record in nonconference play,'' Turner said. ''It is special for us and I am grateful.''
Oregon played without transfer guards Brennan Rigsby and Jermaine Couisnard, who are out indefinitely due to injury. It matched the largest margin of defeat in a nonconference home game for the Ducks since a 67-54 loss to Virginia on Dec. 18, 2011.
''A poor mental effort,'' Altman said. ''We didn't compete. I wish I had something positive to say, but really disappointed. The guys are disappointed. I'm disappointed. Got punched right from the start.''
UC Irvine built a 35-22 lead at halftime and stretched the margin when Bent Leuchten scored to open the second half and Devin Tillis added a three-point play to push the lead to 40-22.
Dante made a free throw to cut the lead to 42-26 with 18:03 left to play, but the Ducks couldn't get much closer the rest of the game.
UC Irvine built an early 12-4 lead before Oregon took an 18-17 lead on two free throws by Kel'el Ware with 6:11 left in the first half.
The Anteaters closed out the half with a 18-5 run to take a 35-22 lead at the half.
UC Irvine: The Anteaters improved to 2-0 with a couple West Coast Conference teams ahead in Loyola Marymount and Pepperdine before hosting Life Pacific. There is not likely another ranked opponent on UC Irvine's schedule this year.
Oregon: The Ducks opened the season with a win over Florida A&M and looked likely to start 3-0 with wins expected over UC Irvine and Montana State before the schedule gets tougher. Oregon's nonconference schedule is loaded in the middle with a home game against third-ranked Houston on Sunday followed by a trip to the Phil Knight Invitational where they could face No. 1 North Carolina, No. 16 Villanova, or No. 20 Alabama. After that, Oregon opens Pac-12 play against Washington State and No. 8 UCLA before wrapping up nonconference games against four non-power conference programs.
UC Irvine: The Anteaters host Loyola Marymount on Tuesday.
Oregon: The Ducks stay home to face Montana State on Tuesday.
