Duke is back at No. 1, moving up a spot following a pair of victories last week.
The Blue Devils can thank Evansville for the jump.
Duke moved to No. 1 for the first time this season, receiving 52 first-place votes from a 65-member media panel in The Associated Press mens college basketball poll released Monday.
The Blue Devils climbed a spot after unranked Evansville pulled off the seasons biggest surprise so far by knocking off previous No. 1 Kentucky.
Duke is ranked No. 1 for the 143rd week, extending its own record, and has the top spot in the AP poll for the 20th season under coach Mike Krzyzewski, also a record.
