EUGENE, Ore. (AP) - Oregon defensive coordinator Nick Aliotti has surely become accustomed in recent years to all the attention falling on the Ducks' speedy spread offense. So when the spotlight falls on Oregon's defense, Aliotti's pride is apparent.

The defense starred last weekend when No. 2 Oregon shut out Arizona 49-0. Six times the Ducks prevented the Wildcats from scoring from the red zone.

Interceptions by sophomores Ifo Ekpre-Olomu and Troy Hill were returned for touchdowns, and overall the Ducks had four interceptions returned for 99 yards. Linebacker Michael Clay had 13 tackles, including two for loss, to earn Pac-12 player of the week honors.

The shutout was the first in conference play for Oregon since a 35-0 win over Stanford in 2003.
