Syracuse, off to the best start in school history, is the first unanimous No. 1 in The Associated Press poll since Duke was for six weeks in 2010-11.

The Orange (21-0) are on top of the poll for the first time since a six-week run in 2011-12. They received all the first-place votes Monday from the 65-member national media panel.

Arizona (21-1) and Syracuse, which had been 1-2 for the past eight weeks, switched places after the Wildcats lost at California on Saturday.

The Orange remained unbeaten with a 91-89 overtime win over Duke on Saturday, and continued their red-hot play Monday with a 61-55 victory over visiting Notre Dame in their first game as No. 1.

"We're happy to be No. 1," coach Jim Boeheim said Monday. "Obviously, it's taken a lot of hard work. It's an honor. We'll try to keep playing well."

This is the 15th week Syracuse has been No. 1, tying DePaul and Massachusetts for 17th place all time.

Syracuse is the fourth team to hold the No. 1 ranking this season after Kentucky, Michigan State and Arizona.

Florida, Wichita State (the only other unbeaten in Division I) and San Diego State remained third through fifth and were followed by Villanova, Cincinnati, Kansas, Michigan State and Michigan. Texas made the biggest jump inside the Top 25 this week, moving from 25th to 15th.

The Longhorns (17-4) are on a six-game winning streak. The past four wins have been against teams that were ranked at the time: No. 8 Iowa State, No. 22 Kansas State, No. 24 Baylor and No. 6 Kansas. Add in their early season win over then-No. 14 North Carolina and the Longhorns have five wins over ranked teams.
