Syracuse (21-0) received all 65 first-place votes from the national media panel Monday, making the Orange the first unanimous No. 1 since Duke was for six weeks in 2010-11.
Arizona (21-1) and Syracuse, which were 1-2 for the last eight weeks, switched spots this week. 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.
Duke, which also won at Pittsburgh last week, was 11th, a jump of six spots from last week's poll. No. 20 Virginia, No. 22 Connecticut and No. 23 Gonzaga returned to the rankings. They replaced Ohio State and Wisconsin, which both reached as high as No. 3 this season, and Massachusetts.
