Dayton's 25-point rout of previously unbeaten Pittsburgh over the weekend moved the Flyers into the Associated Press' Top 25 for the first time in four years.
The 80-55 win over then-No. 6 Pittsburgh on Saturday was the 10th straight for the Flyers (11-1) since a 67-56 loss at George Mason. They joined the poll at No. 20, their first ranking since a three-week run in December, 2003.
North Carolina remained No. 1, the spot it has held since the preseason poll. Memphis and Kansas stayed second and third for the fifth straight week.
Stanford and Wisconsin joined Dayton as newcomers this week, replacing Miami, BYU and West Virginia.
Brian Roberts (St. John's Jesuit graduate) had 31 points for Dayton in the win over Pittsburgh. The senior guard is in the top five in seven statistical categories in the Atlantic 10.
"I've been saying all along that he is one of the most efficient guards in the country, averaging 19 points on just 11 shots a game while having a great assist-to-turnover ratio," Dayton coach Brian Gregory said. "But with what he's done this year that's not good enough. He is one of the best all-around guards in the country. He has run our offense but knows when he has to take over and he has carried us in stretches."
The Tar Heels (13-0), who beat Nevada and Valparaiso this week, received 45 first-place votes and 1,772 points from the 72-member national media panel.
Memphis (11-0), which beat Arizona 76-63 on Saturday, was No. 1 on 26 ballots and had 1,744 points, Kansas (13-0), which beat Yale in its only game last week, received the only other first-place vote.
Washington State and UCLA held fourth and fifth. Michigan State and Georgetown both moved up one place from last week to sixth and seventh, while Tennessee, Duke and Marquette rounded out the top 10.
WOMEN'S POLL: Connecticut held the top spot for the second straight week. The Huskies received 49 of the 50 first-place votes. Stanford, which received the other first-place vote, held the No. 2 position. Ohio State fell four spots to No. 21 after losing to Michigan State.
