Oregon State coaches have said they'll make their quarterback pick between Sean Mannion and Cody Vaz when one of them makes himself the clear-cut choice.
That hasn't happened yet.
Beacers coach Mike Riley will select a starting quarterback as the team prepares for its Aug. 31 opener against Eastern Washington.
A Friday scrimmage at Reser Stadium was the last of 15 spring practices for Oregon State, which had a bounce-back year in 2012 with a 9-4 record and a postseason bowl after winning a combined eight games the previous two seasons.
Mannion and Vaz each played one series in the two-hour scrimmage.
Mannion went first, going 8 of 11 for 67 yards and an interception. Vaz was 4 of 6 for 59 yards. His series produced a 1-yard touchdown run by Terron Ward.
Brandin Cooks was the leading receiver with four catches for 38 yards. Chris Brown carried 21 times for 43 yards.
