Mike Buck knew it doesn't get much better than this.

He wasn't just good, he was perfect.Jumper . . . swish.

Free throw . . . swish.

Every time he took a shot . . . swish, swish, swish.

And when it was all over, Middle Tennessee State scored the final 21 points of the game - yes, 21 consecutive points to end the game - and beat 13th-ranked Florida State 97-83 in the NCAA tournament's Southeast Regional.

"After the first couple of threes, I just kept shooting," Buck said. "We needed somebody to do something. They didn't know who I was. Now, I'm not sure I'm used to all this attention."

Buck was 7-for-7 from the field, including 6-for-6 on three pointers. He was 6-for-6 from the free-throw line.

He scored 15 consecutive points during the 21-0 run. Florida State, which led 67-50 five minutes into the second half and 83-76 with 5:05 to go, was blown away.

"I've never been involved in a game where it went from one end to the other so quickly," Seminoles coach Pat Kennedy said. "It was almost like an avalanche, where it just kept coming and coming. They kept making all their shots. We're up by 17 and before you know it, we're down by 14."

For the Blue Raiders, 23-7, it was their biggest victory since they upset Kentucky in the 1982 tournament.

"These guys played their hearts out," Middle Tennessee State coach Bruce Stewart said. "We were 17 points down and a lot of people started walking up the aisles. A lot of people gave up on us. But these guys - they never, ever gave up."

Tony Dawson scored 21 points for the Seminoles, 22-10, and Tharon Mayes added 20. Randy Henry scored 26 points for Middle Tennessee.

No. 9 Duke 90, S. Carolina St. 69

At Greensboro, N.C., Phil Henderson scored a career-high 22 points and Danny Ferry added 18 as the Blue Devils dominated inside and won their sixth consecutive first-round game.

Siena 80, No. 13 Stanford 78

Marc Brown made two free throws with three seconds left as Siena, which blew a 16-point lead, became the fifth 14th seed to win a first-round game since the tournament expanded to 64 teams in 1985.

B Brown twice missed the front end of one-and-ones in the final minute that might have have clinched the game - and then sank the game winners.

Siena, 25-4, was playing before fans for the first time in 10 games. The Saints had played their last nine in empty arenas because of a measles outbreak at their campus at Loudonville, N.Y.

No. 17 West Va. 84, Tennessee 68

Herbie Brooks scored 22 points and Ray Forster added 19 for the Mountaineers, 26-4, who took a 17-5 lead behind an 8-0 run.

West Virginia, 26-4, led 34-19 with 2:28 left in the first half and 47-27 with 16:53 remaining in the game.

Minnesota 86, Kansas St. 75

Willie Burton scored 18 of his 29 points in the first half and Minnesota took a 28-14 lead in the first 11 minutes.

The Golden Gophers, 18-11, held on in the second half as Kansas State, 19-11, used a full-court press for a 14-4 run, closing within 67-62 with 4:39 left.

Minnesota then appeared to turn the ball over on the inbounds pass, but the officials awarded it to the Golden Gophers. Mevin Newburn made a 3-pointer with 3:50 left, Minnesota's first basket in 4:38, and two free throws 20 seconds later, giving the Golden Gophers a 72-62 lead.
