Sean Mannion threw for 267 yards and two touchdowns and Oregon State defeated the mistake-prone Arizona Wildcats 37-27 on Saturday for the Beavers' first victory of the season.
Quarterback Nick Foles was intercepted twice and the Wildcats (1-5, 0-3 Pac-12) lost two fumbles in their fifth straight loss overall and eighth straight conference loss.
Oregon State (1-4, 1-2) led 27-6 at halftime and nearly squandered it but held on to snap a six-game losing streak dating back to last season.
With only a narrow 30-27 lead and 5:22 left, Oregon State went for it on fourth-and-2 - succeeding when Mannion hit diving tight end Joe Halahuni for the touchdown.
The Beavers made a crucial stand on the other end when the Wildcats also took a chance a fourth down with two yards to go, and Dan Buckner couldn't catch Foles' pass in the end zone.
