Corvallis, OR (Sports Network) - Ryan Katz threw for 154 yards and two touchdowns while Jacquizz Rodgers ran for 128 yards and a score, as Oregon State stifled No. 20 Southern California, 36-7, at Reser Stadium.

Katz completed 17-of-24 passes for the Beavers (5-5, 4-3 Pac-10), who had lost their last two. Oregon State recorded its largest margin of victory over the Trojans since the teams' initial meeting in 1914.

USC (7-4, 4-4) played the final two quarters without quarterback Matt Barkley, who suffered an apparent ankle injury at the end of the first half. Barkley completed 10-of-19 passes for 75 yards with an interception, which cornerback Jordan Poyer returned 65 yards for a score to help the Beavers snap the Trojans' two-game win streak.

It appears that Barkley will likely miss the final two games of the season, per this tweet from the USC athletic department:

Barkley suffered a high-ankle sprain & judging by his comments will need to be a miraculous healer to come back in 2 weeks.No official news.

USC hosts Notre Dame next Saturday night.
