OREGON STATE WON: The inspired Beavers completely shut down the Wisconsin offense, holding the No. 13 Badgers to 206 total yards in a 10-7 upset win. Quarterback Sean Mannion was 30 of 48 for 285 yards and a touchdown, and receivers Brandon Coook and Markus Wheaton combined for 15 receptions, many of the clutch variety. The usually powerful Badgers run game was slowed to a crawl, as Wisconsin managed just 35 net yards on the ground. Heisman Trophy candidate Montee Ball had just 60 yards on 15 carries, and his longest run was 14 yards.
WHY OREGON STATE WON: The Beavers needed to hold their own in the trenches against Wisconsin's physical, smash-mouth style, and that's exactly what they did. The holes just weren't there for the Badgers running backs to run through, thanks to a swarming OSU defense. With the run game taken away, it was up to Danny O'Brien to win the game, and he managed just 171 yards through the air.
WHEN OREGON STATE WON: This game wasn't really in hand until the very end. Down 10-7, Wisconsin attempted an onside kick and appeared to recover the ball with 1:11 left and a chance to at least tie the score. But the officials ruled that there was a violation on the play, awarding the ball to Oregon State. The Beavers then ran out the clock, and coach Mike Riley had his biggest win since upsetting No. 1 USC in 2008.
WHAT OREGON STATE WON: Some respect for the Pac-12. With losses to Utah State and Sacramento State already in the bag, the conference was poised for a disastrous weekend. Oregon State stopped the bleeding with the biggest upset of the day so far.
WHAT WISCONSIN LOST: A chance at a national title. The Badgers were a trendy preseason choice to run the table, but this shocking loss put that idea to rest, if it already hadn't happened the week before in a 26-21 win over Northern Iowa. Wisconsin will need to regroup quickly if it wants to compete for the Leaders Division title.
THAT WAS CRAZY: Ball had scored at least one touchdown in 21 consecutive games dating to the 2010 season. That streak was snapped against the Beavers.
