Drew Neitzel scored 28 points last night to lead host Michigan State to a 64-55 victory over No. 1 Wisconsin, whose stint as the nation's top-ranked team might be short-lived.

Neitzel's three-pointer with 3 minutes 51 seconds left gave the Spartans a 51-49 lead, and Michigan State (20-8, 7-6 Big Ten) held on for the victory, giving its NCAA tournament hopes a boost.

Wisconsin gained the No. 1 spot in the Associated Press poll for the first time in school history on Monday.

The sellout crowd at Breslin Center serenaded the Badgers with a chant of "over-rated" as the clock wound down. Students stormed the court at the final horn.

"If you start to chant 'overrated,' I'm leaving," Wisconsin Coach Bo Ryan joked before addressing reporters in his postgame news conference.

Ryan said he didn't think the pressure of playing with the No. 1 ranking affected his team's performance.

"I don't think that had anything to do with it," Ryan said. "Michigan State played better."

The upset put a damper on Wisconsin's showdown Sunday with No. 2 Ohio State.

The Badgers (26-3, 12-2 Big Ten) trailed 7-0 after Ryan picked up a technical foul for complaining about the lack of a foul call on a Michigan State offensive rebound.

After Ryan cooled down, the Badgers heated up and went on a 16-3 run to take a 16-10 lead. Despite getting outrebounded by a nearly 2-to-1 margin in the first half, Wisconsin was able to head to the break with a 30-29 lead behind Alando Tucker's 14 first-half points.

Marcus Landry had 18 points for Wisconsin. Tucker had 16, but only two in the second half.

· PROVIDENCE 64, WEST VIRGINIA 61: Weyinmi Efejuku had 24 points and seven rebounds, and the Friars took advantage of the 22nd-ranked Mountaineers' 32 missed three-point attempts.

Providence (17-9, 7-6 Big East) improved to 16-2 at home and 3-3 against ranked teams as it tries to move off the NCAA tournament bubble.

Darris Nichols and Frank Young scored 14 apiece for the Mountaineers (20-7, 8-6).

· UNLV 60, AIR FORCE 50: Kevin Kruger had 14 points and a career-high 10 assists to help the Rebels beat the No. 14 Falcons (23-5, 10-4 Mountain West).

Kruger was 2 of 11 from the field but 9 of 9 from the line. Joel Anthony added 10 points and nine rebounds for UNLV (23-6, 10-4), which won its 13th straight home game.

· TEXAS 80, TEXAS TECH 51: In Austin, A.J. Abrams scored 18 points and the No. 19 Longhorns stayed in the thick of the Big 12 race.

Kevin Durant added 17 points for Texas (20-7, 10-3).

Alan Voskuil scored nine points to lead the Red Raiders (17-11, 6-7).
