Oregon State coach Mike Riley has named Sean Mannion the starting quarterback for the No. 25 Beavers ahead of their season opener on Saturday against Eastern Washington.

The announcement Monday was the culmination of the fall camp competition between Mannion and Cody Vaz, who both played at quarterback last season. Both players shared first-team reps for the past several weeks.

Mannion started Oregon State's first four games last season but injured his left knee and required arthroscopic surgery. Vaz stepped in and won the next two games, giving the Beavers their best start since they also went 6-0 in 1907. Oregon State finished a better-than-expected 9-4 and earned a trip to the Alamo Bowl, where it lost to Texas 31-27.
