Oddsmakers have the unranked Arizona Wildcats installed as three-point favorites over visiting Oregon State, the 18th-ranked team in the nation, this Saturday in Tucson.

Arizona (3-1, 0-1 in Pac-12) lost its first game of the season last weekend at Oregon, drubbed 49-0. Now the Wildcats get the Beavers (2-0, 1-0), who have had a game postponed and a bye already this season but have taken out two ranked teams, Wisconsin and UCLA (now unranked).

Oregon State's defense is a force to be reckoned with. It held UCLA's star running back Johnathan Franklin to 45 rushing yards after he came into the game as the nation's leading rusher. The Beavs also showed great balance on offense, as quarterback Sean Mannion passed for 379 yards and two scores and running back Storm Woods ran for 96 yards and a touchdown.

This might not be a favorable matchup for Arizona. The 'Cats can move the ball, but will be facing another fast, athletic defense for the second time in two weeks. That said, they're still home favorites in Tucson.
