Singler's heroics came seconds after Washington State's Royce Woolridge buried a three to tie the game up. It was the second such clutch three on the night for the Cougars (11-15, 2-11 Pac 12), as DaVonte Lacy tied the game at 71-71 with nine seconds left in regulation.
Singler led the Ducks with 25 points on 6-of-11 shooting and 4-of-8 from three-point range. He also knocked down 9-of-10 from the charity stripe. Carlos Emory had 20 points off the bench and Damyean Dotson added 16 points for the Ducks (21-5, 10-3 Pac 12), who remain atop the Pac 12.
Oregon trailed by as many as 15 in the first half and went into the half down 38-27. The Ducks immediately opened the second half on a run to get back in the game, and took a lead with just under six minutes left in regulation that looked like it was going to hold up before Lacy's late three sent the game to overtime.
Oregon survived a monster performance from Woolridge, who led the Cougars with 36 points on 10-of-15 shooting. Woolridge made 6-of-9 from deep and also knocked down 10-of-11 from the free throw line.
