STANFORD -- Dwayne Benjamin made one of two free throws with 14 seconds remaining to give Oregon the lead in a 73-70 victory over Stanford to clinch the third seed and a first-round bye in the upcoming Pac-12 Conference tournament.
Joseph Young, who scored 21 points, sank a pair of free throws with three seconds left after a missed Stanford shot.
Elgin Cook also scored 21 points for the Ducks (22-8, 12-5 Pac-12), who won their fourth straight and eight of nine overall. Benjamin finished with 15 points.

Brown gave Stanford a 60-59 edge on a driving layup with just under seven minutes remaining in the contest. He extended the lead a minute later with a short jumper.
Oregon kept coming, though, and tied the game on Benjamin's 3-pointer from the corner with 3:26 left. The Ducks took the lead moments later when Bell blocked a shot at one end of the court and slammed the ball through the net on the other end.
The game was tied at 70 heading into the final minute. The teams traded turnovers, with Benjamin stealing the ball and getting fouled with 14 seconds left to play.
