No. 6 Nevada, Gonzaga, Michigan State, Florida State and Virginia Tech rounded out the top 10.
Duke (11-1) started the season No. 4 in the preseason poll, but moved to No. 1 for a record-tying 135th week in the first regular-season poll after turning its opener against then-No. 2 Kentucky into a laugher.
The Blue Devils stayed in the top spot until a rally against Gonzaga in the Maui Invitational title game came up short. Duke worked its way up to No. 2 and slid into the top spot after routing Princeton and holding off No. 12 Texas Tech last week.
The 69-58 win over the previously-unbeaten Red Raiders had a March-like feel at Madison Square Garden as two Elite Eight teams from a year ago played for the first time.
“This is a great night for college basketball,” Duke coach Mike Krzyzewski said.
