Baylor overtook Ohio State in The Associated Press college football poll and Alabama became just the seventh team to hold the No. 1 ranking for 13 straight polls in a season.
The third-ranked Bears slipped ahead of the fourth-ranked Buckeyes after Baylor beat Texas Tech 60-34 and Ohio State won 60-35 at Illinois on Saturday. Baylor has 1,351 points and Ohio State has 1,343.
Alabama remained No. 1, with 55 first-place votes from the media poll released Sunday. No. 2 Florida State has five first-place votes.
Oregon was fifth and Auburn was sixth.
Alabama has been No. 1 since the preseason. Only six preseason No. 1 teams have had longer uninterrupted stays than the Tide, including Southern California in 2004 and Florida State in 1999, the only wire-to-wire champions.
The other four preseason No. 1 teams that have spent longer at No. 1 than Alabama all either lost in a bowl game (Nebraska, 1983; Southern California, 2005; Ohio State 2006) or lost in a conference title game (Oklahoma, 2003).
Moving into the rankings was No. 23 Southern California, No. 24 Mississippi and No. 25 Duke. The Blue Devils were last ranked in December 1994.
