Roberto Nelson scored 13 of his 22 points in the second half and anchored a stellar defensive effort that carried the Beavers to an 80-72 Pac-12 victory over Oregon Sunday night.
Eric Moreland added 15 points, 11 coming from the free throw line and had 13 rebounds for Oregon State (10-7, 2-3 Pac-12). The Beavers beat their in-state rivals at Gill Coliseum for the first time since 2010 and sent the slumping Ducks to their fourth consecutive loss.
Jason Calliste finished with 17 points and Richard Amardi had 13 points and six rebounds for the Ducks (13-4, 1-4).
