Arizona and Syracuse lead the same first five teams in The Associated Press' Top 25 poll for the fourth straight week.
The Wildcats (13-0) saw their lead in first-place votes change for the first time Monday. They received 60 No. 1 votes from the 65-member national media panel, three fewer than they got the past three weeks.
Syracuse (12-0), which beat previously unbeaten Villanova on Saturday, was No. 1 on the other five ballots.
Three Big Ten teams -- Ohio State, Wisconsin and Michigan State -- remained third through fifth.
Oklahoma State moved up one spot to sixth, while Duke, Wichita State, Baylor and Oregon all jumped two places to round out the top 10.
Louisville, which lost at Kentucky on Saturday, dropped from sixth to No. 14. Villanova fell three places to 11th.
Eight teams remain unbeaten, and only Toledo (12-0) is unranked. The Rockets, however, play at No. 16 Kansas on Monday night and will try to end the Jayhawks' 67-game home win streak against nonconference opponents.
There are still two Division I teams yet to get a win this season: Cornell (0-12) and Grambling State (0-7).
Arizona has now been on top of the AP poll 33 times, breaking a tie with UNLV for ninth place on the all-time list. Next up on the list for the Wildcats is Ohio State, which has been No. 1 on 37 occasions, the last in 2010-11.
UCLA is the leader with 134 weeks at No. 1. Then come Duke (127), North Carolina (111), Kentucky (93), Kansas (57), Indiana (54) and Cincinnati (45).
