CORVALLIS, Ore. (AP) -- Sean Mannion threw for 276 yards and a touchdown, Oregon State's defense smothered Wisconsin's Montee Ball and the Beavers upset the No. 13 Badgers 10-7 on Saturday.
Mannion connected with Brandin Cooks on a 20-yard touchdown on the opening drive of the second half to give the Beavers a 10-0 lead then turned it over to the Oregon State (1-0) defense that forced two turnovers and held Ball to 61 yards rushing.
The win snapped Wisconsin's 33-game non-conference winning streak, the second-longest in the country behind LSU.
Wisconsin finished with 207 yards and only 35 on the ground. It was the lowest total yardage for Wisconsin in five years. The previous non-conference loss for Wisconsin (1-1) came early in the 2003 season when the Badgers lost to UNLV.
