CORVALLIS — Luke Jackson scored a career-high 39 points and grabbed a personal-best 16 rebounds.
The Ducks still lost. It was that kind of a night for Oregon.
Oregon State allowed its fans a chance to witness the first victory against the Ducks since 1999. The Beavers outlasted Oregon, scoring the game’s final 13 points for the 90-81 victory.
“We got outplayed,” Oregon forward Ian Crosswhite said. “We made some key mistakes down the stretch.”
Oregon State’s win ruined a 39-point night by Jackson, the most points in a single game by a Duck since Orlando Williams scored 40 against Washington State on Feb. 12, 1994. The forward scored 23 points in the second half and was perfect from the free-throw line at 14 of 14.
It just wasn’t enough against the Beavers.
“I thought my teammates were looking to me to make plays,” said Jackson. “I may have been guilty of trying to make too many plays. That put our offense a little out of whack.”
The Ducks did end the game shooting 47.2 percent from the field but failed to capitalize late in the game. Oregon State made seven free throws in the final 2:54 of the game and of its final 13 points, made eight from the paint.
David Lucas led Oregon State (7-6 overall, 1-2 Pac-10) with 24 points on the strength of 9 of 13 shooting. He was an inside presence the Ducks were not able to battle, compounded with Ian Crosswhite getting four fouls by the 13-minute mark of the second half.
“We gave them way too much confidence,” Jackson said. “They battled us. We played poor defense.”
Oregon State came on strong, taking a 12-2 lead in the first three minutes of the game. The Ducks did not make a field goal until the 14:34 mark when Jackson made his first two points of the night.
Oregon (6-4, 1-2) fought back, eventually tying the game, 14-14, with 12:45 remaining. From then on, it was a seesaw battle, with both teams virtually matching each other point for point until the Beavers took a 36-35 lead at halftime.

“They came out with more heart,” Oregon guard James Davis said. “They wanted the game more than we did.
“They just wanted it more and out-hustled us.”
Oregon came out strong in the second half, spurred by three early three-pointers by Davis. He ended the game with five from beyond the three-point arc, but he didn’t score in the final 16 minutes and missed three-pointers that would have given the Ducks the lead or at least would have pulled them closer to Oregon State.
“That shot at the end by James just didn’t drop,” Crosswhite said. “We got out-toughed and they played harder than us.”
Lucas scored 22 points in the second half, hitting on 8 of 10 shots and sinking six free throws. He led the Beavers with seven rebounds, grabbing four in the second half and had two key blocks.
As a team, the Beavers shot 47 percent of the field, including 56.3 percent in the second half.
“They believed the whole game they could beat us,” Jackson said. “Early on, they hit all those threes. In the second half, we just gave them too many looks.”
Oregon must now regroup from the loss and look forward to next week when Washington and Washington State visit McArthur Court.
The Ducks sit in the middle of the conference and are coming off two losses — including an 81-74 setback coming from UCLA last week — and must get well before traveling to Arizona and Arizona State in less than two weeks.
“You have to look at what you did wrong and you have to correct it,” Jackson said. “But at the same time, you turn around and you’ve got Washington and Washington State coming in at home. Those are two good ballclubs. You have to focus on what they do well, look at game tape and see where we went wrong.”
The Ducks now sit in the middle of the Pac-10 race.
Oregon hosts Washington at 6 p.m. on Thursday.
