Tyrone Nesby hit a short jumper to put UNLV ahead, then clinched it with two free throws with 9.9 seconds left Saturday night as the Runnin' Rebels beat No. 20 New Mexico 56-51 in Las Vegas to win the Western Athletic Conference championship.

Before a frenzied home crowd, UNLV scored the last nine points of the game to cap an improbable run through the WAC tournament and gain an automatic bid to the NCAA tournament for the first time since 1991.UNLV led most of the game, but trailed by a point when Nesby hit a 10-footer from the side to put the Runnin' Rebels ahead 52-51 with 1:18 left. After a New Mexico miss, Mark Dickel was fouled with 29.2 seconds remaining and made both free throws to give UNLV a three-point lead.

Lamont Long missed on two successive free throws and Nesby was fouled after getting the rebound, sending him to the line to ice the game with two more free throws.

The win was the fourth of the tournament for UNLV, which upset No. 5 Utah in the quarterfinals.

UNLV (20-12) had been given little chance to make the NCAA tournament unless it won the WAC tournament, and it did just that, taking advantage of a boisterous home crowd to play inspired defense throughout the tournament.

With fans singing "Viva Las Vegas," UNLV's tight defense forced the Lobos to shoot from the outside much of the game.

New Mexico (23-7) beat UNLV twice during the regular season and appeared ready to do it again when Kenny Thomas went inside for a layup that gave the Lobos a 51-47 lead with 2:44 left in the game.

That was the last points New Mexico would score, however, as Dickel hit a 3-pointer to get UNLV close and Nesby followed with a jumper to put the Rebels ahead.

It was the sixth win in a row for UNLV, which is 9-2 since suspended star center Keon Clark left the team for good.

Brian Keefe led UNLV with 18 points, Nesby had 14 and Kevin Simmons 13. Thomas had 17 points and 13 rebounds for New Mexico while Long had 12 points.

UNLV led the entire first half, taking its biggest lead of the game when Keefe hit a 3-pointer with 8:44 left to make it 23-10.

New Mexico came back with 10 straight points to cut the gap, but Keefe hit two more 3-pointers to help give the Runnin' Rebels a seven-point halftime lead.

NO. 1 DUKE 66, CLEMSON 64: At Greensboro, N.C., Duke needed a tip-in by freshman William Avery with less than a second left to beat Clemson and advance the Atlantic Coast Conference final against No. 4 North Carolina.

Elton Brand's tip-in with 15 seconds left put the Blue Devils (29-2) up 64-61. Clemson (18-13) raced down the court and Terrell McIntyre put up a 3-pointer that hit the front of the rim, bounced up near the top of the backboard and fell through the basket with 7.8 seconds remaining.

Duke came back and Avery put up a runner in the lane that bounced off the rim and caromed off to the right. But he tipped the ball back up off the backboard and in with three-tenths of a second remaining.

NO. 2 ARIZONA 91, NO. 19 UCLA 87: At Los Angeles, Michael Dickerson scored 30 points - two off his career high - as No. 2 Arizona avoided its second straight upset loss.

Williams made 2-of-3 free throws with four seconds left in regulation to tie the score at 66-66, then took over in overtime, scoring on a fast-break layup, a shot in the lane, a 19-footer and four free throws as the Tar Heels (29-3) scored on their first nine overtime possessions.

NO. 17 MICHIGAN 85, MINNESOTA 69: At Chicago, Louis Bullock scored 23 points and Robert "Tractor" Traylor added 18 as Michigan showed its inside-outside versatility to beat Minnesota.

Michigan's 3-point shooting - the Wolverines made 13 Saturday - and the play of the burly Traylor were too much for Minnesota, which had beaten Northwestern and upset top-seeded Michigan State in the first two rounds.

Jerod Ward added 17 points for the Wolverines (23-8), who used a 15-0 first-half run to build a sizable lead and an 11-0 spurt in the second to finally secure the victory.
