WATCH: Sooner backs Perine, Mixon run wild early in Bedlam Series

The Sooners pulled out to a big lead early in the do-or-die Bedlam game against archrival Oklahoma State, thanks largely to the efforts of running backs Samaje Perine and Joe Mixon. 

Sophomore Perine gave the Sooners a 14-10 lead with this 68-yard touchdown run:

Redshirt freshman Mixon chipped in with this 66-yard touchdown to match it, giving Oklahoma an even larger advantage:

The two touchdowns fueled the Sooners to a 58-23 win over the Cowboys. By winning the latest edition of the Bedlam Series -- and thanks to TCU defeating Baylor on Friday -- Oklahoma will now be crowned the 2015 champions of the Big 12 Conference.
