Michigan State is on top of the Associated Press top 25 poll for the first time in more than a decade.
The Spartans (3-0) moved up a spot in the latest poll Monday after knocking off previous No. 1 Kentucky last week.
Michigan State received 51 of 65 first-place votes.
Michigan State last held the top ranking in the AP poll in the 2000-01 season. Before that, the Spartans had a two-week run at No. 1 during Magic Johnson's national title season in 1978-79.
After beating Kentucky at the Champions Classic in Chicago last Tuesday, Michigan State coach Tom Izzo said he welcomed the "fun" and "pressure" that wearing the crown as the top-ranked team in the nation brings.
"If we have that, I think it's great for us," Izzo said. "We have to learn to handle that kind of thing. And we'll see now, when we get back to campus, are we gonna (be serious)? I want them to enjoy the game. I told them a year's a process of these games. But there's gonna be a little added pressure on, a little more. But that's the fun, man."
Kansas (3-0), which beat Duke in the second game of the Champions Classic doubleheader, moved from fifth to No. 2 and received seven first-place votes. Louisville (3-0) remained at No. 3 and got the remaining seven top votes.
Kentucky (3-1) fell to fourth. Arizona (3-0), Duke (2-1), Oklahoma State (3-0), Ohio State (3-0), Syracuse (3-0) and VCU (3-0) rounded out the top 10.
