After Oklahoma trounced Ohio State 31-16 on Saturday night, the team leapfrogged the Buckeyes again Sunday afternoon, this time in the Associated Press poll.

The Sooners supplanted Ohio State as the No. 2 team, moving up three spots for the program’s highest ranking since 2011. The Buckeyes slid to No. 8 and are the highest ranked team with a loss.

Oklahoma picked up a pair of first-place votes from Kellis Robinett of the Wichita Eagle and Jon Wilner of the San Jose Mercury News.

So why did Robinett and Wilner put Oklahoma ahead of Alabama?

Robinett, who covers Kansas State, explained it in a blog post.

“Winning at Ohio State is the most impressive win any team has pulled off two weeks into this young college football season,” he wrote. “For that, Oklahoma deserves to move up in the national polls.”

The Sooners, preceded by only No. 1 Alabama, are followed by Clemson, USC, and Penn State in the top five.

With its win against South Alabama, Oklahoma State moved up two spots to No. 9 in the poll while Kansas State came in at No. 18 and TCU at No. 20.

In the coaches’ poll, the Sooners are No. 3 and the Cowboys are No. 8.
