EUGENE — Washington State lulled Oregon to sleep in the first half. Mike Moser woke the Ducks back up.
He scored Oregon's first 11 points of the second half to spark a 67-53 comeback victory against the Cougars Sunday night.
Moser finished with 21 points, eight rebounds, four blocks and a season-high five 3-pointers to lead the Ducks.
"I was just trying to bring some energy," Moser said. "I felt like the first half, Washington State, they kind of play slow and we kind of bit for it."
Joseph Young scored 18 points for the Ducks (18-8, 6-8 Pac-12), who appear to be getting back on track after a midseason slump.
It was the third straight win for Oregon, which started the season 13-0 before losing eight of its next 10.
"It's just us wanting to win," Young said. "Coach can preach about it, but it's just us out there playing and we have come together as team and overcome adversity."
They had some on Sunday, as the Ducks had to overcome a 31-24 halftime deficit and the absence of sophomore guard Damyean Dotson, who didn't play on Sunday after starting 60 straight games.
Dotson, 19, was cited and released early Saturday morning for trying to use a fake I.D. to get into a campus-area bar.
He is averaging 10.7 points and 3.5 rebounds this season but tied his season-high with 17 points against Washington last Wednesday.
Moser said Dotson apologized to the team before the game.
"It's a tough situation for him," Moser said. "Of course he wants to be out there playing. He feels like he let the team down. We all have his back."
Oregon coach Dana Altman said he and Dotson will sit down during the week and discuss his status for Thursday's game against No. 23 UCLA.
"That's between Dot and myself," Altman said. "We'll work through it."
Jason Calliste got his first start of the season in Dotson's place and scored 12 points.
But it was Moser who sparked Oregon. Four seconds into the second half, he made a steal and dunk, followed by 3-pointers on three straight possessions to put Oregon up 35-34.
Moser finished 8 for 13 from the field and made 5 of 7 3-point attempts.
"The energy was just totally different," Altman said. "The pace that we wanted, we got in the second half. The pace they wanted, they had in the first half. I thought the pace changed to our benefit."
Though the Ducks never trailed again, they didn't pull away until late when a dunk by Moser and 13 straight points by Young turned Oregon's four-point lead into a 63-46 advantage.
DaVonte Lacy scored 19 to lead the Cougars (9-18, 2-13).
"Oregon did a nice job coming out after the half and turning up the heat," Washington State coach Ken Bone said. "They were very active and tonight we coughed up the ball."
Washington State shot 27.3 percent in the second half, making just 6 of 25 attempts from the field. The Cougars were also 6 for 22 from the 3-point line overall and had 17 turnovers the Ducks converted into 24 points.
