OMAHA, Neb. (AP) -- Kyle O'Quinn had 26 points and 14 rebounds, making several key plays in the closing minutes, and No. 15 seed Norfolk State held on to stun second-seeded Missouri 86-84 on Friday in the West Regional.
Pendarvis Williams and Chris McEachin each added 20 points for the MEAC champion Spartans (26-9), who made their first trip to the NCAA tournament a memorable one. They became the fifth No. 15 seed to beat a No. 2 and the first since fellow conference member Hampton in 2001.
O'Quinn had a chance to take some of the drama out of the finish when he went to the free throw line with 3.8 seconds to go, but the 70-percent foul shooter missed both tries.
Missouri coach Frank Haith called a timeout with 2.9 seconds left to set up a final play, and the ball wound up in the hands of Phil Pressey. He took a couple of hard dribbles and let loose a 3-pointer from the wing that clanked off the back iron as the buzzer sounded.
Norfolk State advanced to play No. 7 seed Florida in the third round Sunday.
Michael Dixon led Big 12 tournament champion Missouri (30-5) with 22 points, and Pressey and fellow guard Marcus Denmon finished with 20 points each. Pressey also had eight assists.
No. 7 FLORIDA 71, No. 10 VIRGINIA 45
Bradley Beal had 14 points and 11 rebounds, reserve Casey Prather scored a career-high 14 and Florida pulled away in the second half to beat Virginia.
The Gators (24-10) finished the first half on a 17-4 run to shake off a slow start and get out to a 30-22 lead. They shot 70 percent in the second half, pushing their lead to more than 20 points.
Florida made it to the regional finals last season. The Cavaliers were in the tournament for the first time since 2007.
Mike Scott had 15 points for Virginia (22-10).
Florida, averaging a nation-leading 9.9 3-pointers a game, was 4 of 23 from long range but made 24 of 30 from inside the arc.
No. 3 FLORIDA STATE 66, No. 14 ST. BONAVENTURE 63
NASHVILLE, Tenn. (AP) -- Bernard James scored 19 points and Florida State barely avoided a big upset, rallying to beat St. Bonaventure.
The Seminoles (25-9) shook off a slow start and won their sixth straight game, including their run to the Atlantic Coast Conference championship last week. They will play sixth-seeded Cincinnati on Sunday in the third round.
Andrew Nicholson scored 20 points and Demetrius Conger had 14 for St. Bonaventure (20-12), which was trying to win an NCAA tournament game for the first time since 1970.
Florida State used a 16-2 run to take its first lead with 5:15 left on a 3-pointer by Ian Miller. The Seminoles led as much as 60-52 on a dunk by Okaro White with 2:47 left, but had to hold on at the end.
No. 6 CINCINNATI 65, No. 11 TEXAS 59
NASHVILLE, Tenn. (AP) -- Yancy Gates had 15 points and 10 rebounds as Cincinnati started strong and then withstood a late rally by Texas.
The Bearcats (25-10) jumped out to a 16-2 lead while Texas opened the game 1 of 14 from the field and shot 16 percent for the first half. After trailing 31-17 at halftime, the Longhorns attacked, hitting five of their first seven from 3-point range.
With 3:44 to play, Texas' Jonathan Holmes made a layup to tie it at 52, but the Longhorns never took the lead. Gates hit a shot over Clint Chapman with 1:11 remaining to give Cincinnati a 58-52 cushion, and the Bearcats hit five free throws in the final 36 seconds.
J'Covan Brown led Texas (20-14) with 19 points. Chapman had 10 points and 14 rebounds.
No. 1 NORTH CAROLINA 77, No. 16 VERMONT 58
GREENSBORO, N.C. (AP) -- Tyler Zeller had 17 points and 15 rebounds to help North Carolina beat Vermont in its NCAA tournament opener despite playing without injured starter John Henson.
Freshman forward James Michael McAdoo added a season-high 17 points for the Tar Heels (30-5), who pushed ahead by double figures late in the first half and then broke the game open after halftime. They improved to 30-1 in NCAA tournament games played in their home state.
Sandro Carissimo had 11 points for the Catamounts (24-12), who beat Lamar in one of Wednesday's First Four games. That earned them a trip to Greensboro to face the Tar Heels in front of a home-state crowd wearing plenty of light blue.
The Tar Heels didn't turn in a rousing performance, but they had a danger-free afternoon and advanced to play eighth-seeded Creighton on Sunday. They also bought Henson another two days to recover from that sprained left wrist. The 6-foot-10 junior was hurt during last week's Atlantic Coast Conference tournament and missed the last two games in Atlanta.
No. 8 CREIGHTON 58, No. 9 ALABAMA 57
GREENSBORO, N.C. (AP) -- Doug McDermott scored 16 points and Creighton overcame an 11-point deficit in the second half to beat Alabama for its first NCAA tournament victory in 10 years.
Alabama had a chance to win during the frantic final seconds, but Josh Jones blocked Trevor Releford's 3-point attempt from the top of the key as time expired.
McDermott, the MVP of the Missouri Valley Conference and the nation's third-leading scorer at 23.2 points per game, was held scoreless for more than 14 minutes but then scored nine points down the stretch for the Bluejays (29-5).
It was Creighton's first tournament victory since Terrell Taylor drilled a 3-pointer with 0.2 seconds left in double overtime to lift the Bluejays to an upset win over Florida in 2002.
Releford led Alabama (21-12) with 14 points and Trevor Lacey added 13.
No. 3 GEORGETOWN 74, No. 14 BELMONT 59
COLUMBUS, Ohio (AP) -- Jason Clark scored 21 points, Otto Porter added 16 and Georgetown's ruthless defense bottled up Belmont's shooters, sending the Hoyas into the next round of the NCAA tournament after early exits the past two years.
Henry Sims had 15 points for the Hoyas (24-8), who shot 62 percent from the floor and will play No. 11 seed North Carolina State in the third round Sunday.
Georgetown's previous two seasons ended with embarrassing first-round losses to Virginia Commonwealth and Ohio. The Hoyas weren't going to let that happen a third time to a pesky underdog.
The Bruins (27-8) had their 14-game winning streak stopped and fell to 0-5 in NCAA appearances.
Blake Jenkins scored 17 to lead Belmont, which went just 10 of 27 on 3-pointers.
No. 11 NORTH CAROLINA STATE 79, No. 6 SAN DIEGO STATE 65
COLUMBUS, Ohio (AP) -- Richard Howell scored 22 points, double his season average, and North Carolina State used its muscle inside and sticky defense to beat San Diego State.
Lorenzo Brown added 17 points and C.J. Leslie 15 for the Wolfpack (23-12), who improved to 12-5 in NCAA tournament openers. N.C. State has won at least one game in seven of its last eight trips.
Jamaal Franklin had 23 points and Chase Tapley 19 for the Aztecs (26-8), regular-season champions of the Mountain West Conference.
