Arizona's debut at No. 10 in the latest AP poll is a historic one.

Fresh off their 24-17 win at previous No. 2 Oregon last Thursday, the Wildcats became the first team since the poll went to 25 teams in 1989 to move from unranked to the Top 10. Arizona (5-0) is one of 10 undefeated teams left in the country and was ranked as high as No. 2 in the nation on one ballot (by ESPN's Brett McMurphy).

Arizona has not been in the Top 10 in consecutive weeks since 1998, when it moved up a spot in each of the final seven weeks to finish No. 4.

The Wildcats are the highest ranked of six Pac-12 teams in the Top 25, followed by No. 12 Oregon, No. 18 UCLA, No. 20 Arizona State, No. 24 Utah and No. 25 Stanford. USC and Cal also received votes.

Following its win at previous No. 8 UCLA, Utah is ranked for the first time since joining the Pac-12 in 2011. The Utes were ranked for most of the 2010 season, their last in the Mountain West, but dropped out after losing to Boise State in their bowl game.

Oregon and Stanford are in unfamiliar spots after losing in the same week of the regular season for the first time since October 2008.

The Ducks have been ranked lower than No. 12 just once since the beginning of the 2010 season -- and that came in Week 2 of the 2011 seasons, when they were ranked No. 13. Stanford at No. 25 matches its lowest ranking since debuting in the poll's final spot in Week 2 of the 2010 season.
