Arizona State and Utah each followed disappointing losses with three straight victories.
Now they'll face each other in what could be the biggest game of the year for both programs Saturday night at Sun Devil Stadium.
No. 15 Arizona State bounced back from a disappointing home loss to UCLA by knocking off USC, Stanford and Washington.
That puts the Sun Devils in control of the Pac-12 South and with an outside shot at the College Football Playoff, where they're ranked No. 14.
The Utes lost to Washington State at home, but have since beaten UCLA, Oregon State and USC. Utah is No. 17 in the CFB standings and just a half-game behind the Sun Devils in the Pac-12 South.
