DAYTON, Ohio — Go ahead, Louisville. Dance away for yet another day.

The NCAA Tournament's top team pulled off a few dance moves at midcourt during warmups yesterday, then stumbled through a few early missteps.

Louisville's full-court press — the thing that makes the Cardinals so dangerous — took over in the second half, setting up a 74-54 victory over Morehead State that completed 25 years of perfection by No. 1 seeds.

Louisville (29-5) will play No. 9 seed Siena in the second round tomorrow in the Midwest Regional.

With the win, No. 1 seeds improved to 100-0 against No. 16s since the tournament expanded in 1985. There have been a few close calls, and Morehead State (21-16) kept up for a half.

Then, history set in.

"Teams see you as a No. 1 seed, they're going to bring more intensity to you," said Andre McGee, who had five steals at the apex of the press. "That's what makes the tournament so special. Any team can beat another team, regardless of name or ranking."

Samardo Samuels led Louisville with 15 points. Terrence Williams, who danced at midcourt before the game, added 13 points and nine rebounds. Kenneth Faried had 14 points and 11 rebounds for Morehead State.

The University of Dayton Arena became a pressure cooker for two No. 1 seeds from the Big East yesterday. Pittsburgh, the top seed in the East Regional, had the worst of it, unable to shake East Tennessee State until the final minutes of a 72-62 win.

An hour later, the Cardinals took the floor in a mood to party. By halftime, they had that upset feeling in the Pitt of their stomachs.

Williams extended his long, tattoo-covered arms and boogied at midcourt when the Morehead State pep band played "We Got The Funk" during pregame warmups, an indication that the tournament's top team — one with two titles already on its resume — was in the mood for some celebrating.

The Cardinals went to their full-court press right away and forced turnovers to forge a 17-7 lead.

Instead of fading, Morehead State returned to its staples — solid defense and rebounding — to make it a game. Maze Stallworth hit back-to-back 3s that evened it up and set up a little more 1-vs.-16 drama.

By halftime, the Big East's regular-season and conference champs knew the score — leading only 35-33. None of them even spoke or cracked a smile during warmups for the second half.

The dancing was done. Time to get serious.

Williams took only three shots in the first half and had three points, one of the reasons the Cardinals couldn't pull away. He had a pair of jumpers and a 3-pointer during a 22-6 run that opened the second half and set the Cardinals on course for the second round.

Morehead State committed 20 turnovers.

KANSAS 84, NORTH DAKOTA STATE 74

MINNEAPOLIS — Sherron Collins scored a season-high 32 points, and went toe-to-toe with NDSU star Ben Woodside, while Cole Aldrich had 23 points to lead the defending NCAA champions.

Woodside scored 37 points to keep third-seeeded Kansas (26-7) from getting comfortable.

North Dakota State (26-7) was within three points several times down the stretch, but clearly wore down late.

ARIZONA 84, UTAH 71

MIAMI — Nic Wise scored 21 of his 29 points in the second half, Chase Budinger added 20 and the 12th-seeded Wildcats proved it belonged in the field of 65.

Jordan Hill added 17 points and 13 rebounds for Arizona (20-13), which has been in the NCAAs 25 years in a row.

Tyler Kepkay scored 19 points for Utah (24-10), which was 8 for 32 from 3-point range and matched a season-high with 20 turnovers.

CLEVELAND STATE 84, WAKE FOREST 69

MIAMI — Some 23 years later, Cleveland State (26-10) still has a knack for first-round shockers in the NCAA tournament.

The 13th-seeded Vikings raced to an early 17-point lead and stunned one-time No. 1-ranked Wake Forest. The win was reminiscent of the Vikings' only other appearance in the tournament in 1986, when they upset Indiana in the opening round.

Norris Cole scored 22 points for the Vikings, who committed only six turnovers to 18 for Wake Forest (24-7).

Demon Deacons scoring-leader Jeff Teague finished with 10 points.

MICHIGAN STATE 77, ROBERT MORRIS 62

MINNEAPOLIS — Raymar Morgan scored 16 points, and Goran Suton had 11 points and 17 rebounds as second-seeded Michigan State (27-6) bullied Robert Morris (24-11).

Jeremy Chappell was the only player in double figures with 11 for Robert Morris, a commuter school from suburban Pittsburgh making its first NCAA appearance since 1992.

SOUTHERN CAL 72, BOSTON COLLEGE 55

MINNEAPOLIS — Taj Gibson had 24 points on 10-for-10 shooting from the field, sending 10th-seeded USC (22-12) to an easy win over Boston College (22-12).

Dwight Lewis had 20 points, and DeMar DeRozan added 18 points and nine rebounds for USC.

Gibson's perfect shooting was the second-best performance in NCAA tournament history with a minimum 10 attempts, behind Kentucky's Kenny Walker and his 11 for 11 in 1986.

DAYTON 68, WEST VIRGINIA 60

MINNEAPOLIS — Chris Wright scored a career-high 27 points to lead 11th-seeded Dayton (27-7) to its first victory in the NCAA tournament in 19 years.

Charles Little added 18 points for Dayton, which had been 1-13 against Bob Huggins' teams dating to his days at Cincinnati.

Darryl Bryant had 21 points for West Virginia (23-12).

SIENA 74, OHIO STATE 72

DAYTON, Ohio — Siena strikes again.

Ronald Moore hit a 3-pointer with 3.9 seconds left in the second overtime — from the identical spot he made one at the end of the first OT — as ninth-seeded Siena (27-7) beat Ohio State (22-11).

Evan Turner missed a leaner from 15 feet that would have forced a third OT for the Buckeyes, who blew an 11-point lead in the second half of regulation.
