Oregon beats Utah, 64-45, in Pac-12 semifinals LAS VEGAS - Damyean Dotson and E.J. Singler scored 14 points each and Oregon raced away from Utah early for a 64-45 win Friday night in the Pac-12 tournament semifinals. Oregon (25-8) had its regular-season conference title chances spoiled by Utah (15-18) last weekend, but gave the Utes no chance of a repeat upset at the MGM Grand Garden Arena. The third-seeded Ducks built a 14-point lead in the first half and kept the cushion near double figures the rest of the way to earn a spot in Saturday's title game against No. Oregon also stifled Jarred DuBois and Jordan Loveridge, Utah's top two scorers, all night. DuBois missed all eight of his shots and went scoreless, while Loveridge had eight points on 1-of-10 shooting. Utah shot 29 percent and went 5 of 17 from 3-point range. Brandon Taylor had 13 points and senior Jason Washburn added 12 in what's likely his last game for Utah. The Pac-12 had a surprise tournament champion last season, when Colorado won four games in four days to earn the conference's automatic NCAA tournament berth. Utah was hoping to make it two straight to go four in four. The 10th-seeded Utes opened this year's tournament by knocking off No. 7 seed Southern California and followed that up with a 79-69 overtime victory over No. 2 Cal on Thursday night. Oregon also needed overtime to get through the quarterfinals, pulling out an 80-77 win over Washington after Arsalan Kazemi rallied from being benched by scoring 11 of his 14 points in the extra period. Utah had to be optimistic against the Ducks, too. After losing by nine to Oregon on the road, the Utes spoiled the Ducks' bid for the Pac-12 regular-season title with a 72-62 win at home in the regular-season finale. Oregon came out ready to get its revenge for the title-costing loss, limiting the Utes' scoring chances while building a 14-point lead in the first half. Utah made 6 of 19 shots in the first half and had eight turnovers that led to 10 points for Oregon. Dotson led the Ducks with 10 points in the first half. Oregon kept the pressure up to start the second half, hitting five of its first nine shots and going up 41-22 after Emory hit a 3-pointer and threw down a dunk in transition. The Utes tried to fight their way back, pulling within 47-39 after a 12-4 run, but Oregon fought back, not letting them any closer.
