EUGENE, Ore. — Mercedes Wetmore was the last to leave Washington’s locker room at Matthew Knight Arena on Sunday.

After postgame media interviews, quick chats with fans and time to contemplate UW’s 101-85 loss at Oregon alone, she still couldn’t formulate how the game went wrong.

“I’m normally not at a loss for words, but I really am,” Wetmore said. “It just happened so fast.”

Down 76-74 with 6:44 left in the game after a three-pointer by freshman guard Kelsey Plum, the Ducks went on a bruising 13-2 run to pull ahead 89-76 after a three-pointer by Katelyn Loper with 3:20 left in the game.

Oregon sophomore Jillian Alleyne started the run with a layin and kept it going by grabbing key rebounds that her teammates turned into baskets. UW coach Mike Neighbors used his rotation of four post players in different combinations in an attempt to slow Alleyne from bailing Oregon out, but nothing worked.

Alleyne finished with a season-high 34 points on 11-of-17 shooting from the field, with a season-high 25 rebounds — 11 on the offensive end. Washington had 13 offensive rebounds as a team and was outrebounded 58-47 overall.

UW (10-9, 3-5 Pac-12) had no answer for Alleyne, who recorded her 15th consecutive double-double.

“If you’re a beast on the boards, you’re a beast on the boards,” said UW freshman center Chantel Osahor, who had 10 rebounds in a season-high 21 minutes. “I was just trying to take her out of the paint area where she’s not as effective. They called me for a couple of fouls on that, but we gave her everything.”

UW junior forward Aminah Williams agreed.

“There’s nothing you can really say about a great rebounder but that she’s great,” said Williams, who finished with 13 rebounds. “We were just trying to keep fresh legs in there to try to fight.”

Only as the Huskies fought, they were called for more fouls. Alleyne didn’t attempt a three-point shot, but made plenty of three-point plays. She was 10 of 12 from the foul line in the second half.

“Her free throws; she’s improved tremendously on her free throws,” UW forward Talia Walton said. “She’s just perfect for Oregon’s system.”

Even with Alleyne’s dominance, Oregon (11-8, 2-6) still gave Washington open opportunities to shoot its way back into the game. But after taking its first lead, 49-47, after a layin by Wetmore with 17:22 remaining in the second half, UW’s offense stalled.

The Huskies shot 35.4 percent from the field in the game, 2 of 14 from three-point range in the second half. UW junior Jazmine Davis led the Huskies with 30 points while Plum added 23 and Wetmore scored 12 points with seven assists.

“Our effort was there, we just didn’t make our shots,” Neighbors said.
