The Blue Devils advanced one spot to replace Indiana at the top of The Associated Press' Top 25 on Monday, drawing closer to UCLA's record for most No. 1 rankings.
Indiana (9-1) held the top spot from the preseason poll through the first five weeks of the season. Butler beat the Hoosiers 88-86 in overtime Saturday. The Blue Devils (9-0), who were off last week, received 62 first-place votes from the 65-member national media panel.
It is the 123rd week Duke has been ranked No. 1, 11 weeks behind UCLA. All but 31 weeks of Duke's stay on top have come since the 1991-92 season. The Blue Devils' last time at No. 1 was an 11-week run in 2010-11.
Michigan (11-0), which received the other No. 1 votes, and Syracuse moved up one place each to second and third. They were followed in the top 10 by Arizona, Louisville, Indiana, Ohio State, Florida, Kansas and Illinois.
Butler (8-2), which beat then-No. 9 North Carolina last month in the EA Sports Maui Invitational, moved into the poll at No. 19. This is the Bulldogs' first appearance in the rankings since the first week of 2010-11.
Wichita State (9-1) dropped out from 23rd after losing 69-60 at Tennessee. The Shockers spent two weeks in the rankings.
North Carolina, with 107 weeks, is the only other school ranked No. 1 for at least 100 polls.
