NEW YORK — Texas rode its resounding Red River Rivalry upset right to No. 1.

The Longhorns leapfrogged No. 2 Alabama on Sunday and sit atop The Associated Press Top 25 in the regular season for the first time in 24 years after beating Oklahoma 45-35.

Texas' jump to No. 1 is the largest since Miami went from No. 6 to No. 1 on Aug. 29, 1988, after beating preseason top-ranked Florida State 31-0 to start the season.

Texas received 39 first-place votes and 1,599 points from the media panel. Alabama received the other 36 first-place votes and 1,582 points.

The Longhorns are the fourth No. 1 team this season, following Georgia, Southern California and Oklahoma. So it's just more of the same following an unpredictable 2007 season that had four No. 1 teams and eight different teams ranked second.

Unbeaten Penn State moved up three spots to No. 3. The Sooners dropped three spots to No. 4 after their first loss. Florida jumped six spots to No. 5 after pounding LSU 51-21 on Saturday night.
