Earlier in the week USC safety Dion Bailey asked, "Sean Mannion, who's that?" when asked by reporters how the Trojans secondary planned to defend the nation's leader in passing yards and passing touchdowns.
It was a moment that drew a few chuckles from reporters. How could Bailey not know the name of Oregon State's quarterback, No. 4 in Orange and Black?
Turns out, he didn't really need to.
Bailey and the Trojans defense held Mannion to one touchdown on Friday night in their 31-14 win over the Beavers.
They limited the nation's leader in receptions, receiving yards and receiving touchdowns, Brandin Cooks, to six catches for 88 yards including Mannion's lone touchdown.
Bailey, playing with turf toe, intercepted Mannion in the fourth quarter. The Beavers had first and goal inside the five when Bailey stepped in front of OSU receiver Tyler Perry to make the play. It was Bailey's third interception of the season.
