Here's what's happening on the opening day of the NCAA men's basketball tournament:

(12) Little Rock 85, (5) Purdue 83 2OT

Little Rock is moving on in the NCAA Tournament, thanks to an out-of-nowhere comeback that led to an 85-83 double-overtime victory over Purdue.

Josh Hagins sent the game into overtime with a shot from the edge of the midcourt logo, and then into double OT with an arcing shot off glass over an outstretched defender. The six-foot-one senior finished with 31 points, including six in the second overtime.

The 12th-seeded Trojans (30-4), trailed 65-52 with 3:33 to go in regulation, and then went on a 12-0 run to make it a game.

(12) Yale 79, (5) Baylor 75

Makai Mason had a career-high 31 points, including six of Yale's final nine points, and the No. 12 seed Bulldogs held on to upset fifth seed Baylor 79-75 in the first round of the NCAA Tournament on Thursday.

Yale (23-6) earns its first NCAA Tournament victory. It comes in its first appearance since 1962.

Justin Sears added 18 points. Brandon Sherrod finished with 10.

(1) North Carolina 83, (16) Florida Gulf Coast 67

Brice Johnson scored 18 points and No. 1 seed North Carolina needed an overwhelming second-half start to put away 16th-seeded Florida Gulf Coast 83-67.

Isaiah Hicks added 12 points off the bench for the Tar Heels (29-6), who led by just a point after a frustration-filled opening 20 minutes in which the Eagles stayed right with the East Region's top seed. But UNC dominated the opening 10 minutes of the second half, running off a 20-3 burst by controlling the boards and locking down defensively to build a 20-point lead.

That helped the Tar Heels avoid the unwanted history of being the first 1-seed to lose to a 16-seed in tournament history.

(1) Kansas 105, (16) Austin Peay 75

Svi Mykhailiuk scored a career-high 23 points, Perry Ellis added 21 and top-seeded Kansas throttled Austin Peay 105-79..

Landen Lucas scored 16 points for the Jayhawks (31-4), who will face Connecticut on Saturday with a chance to return to the Sweet 16 for the first time since 2013.

Kansas, the No. 1 seed in the South Region, jumped ahead by 20 by halftime and in cruised to its 10th straight win in an NCAA Tournament opener.

(1) Virginia 81, (16) Hampton 45

Anthony Gill scored 19 points and Virginia beat Hampton 81-45 on Thursday in the first round of the NCAA Tournament.

London Perrantes had 12 points and Malcolm Brogdon finished with 11 for the top-seeded Cavaliers (28-6).

They shot 55 per cent, hit 12 3-pointers and put this one well out of reach with a 20-3 run late in the first half before coach Tony Bennett collapsed and was taken to the locker room a few seconds early.

(11) Gonzaga 68, (6) Seton Hall 52

Gonzaga is moving on in the NCAA Tournament after pulling away from Seton Hall for a 68-52 victory Thursday night behind 21 points and 16 rebounds from Domantas Sabonis.

Kyle Wiltjer added 13 for the Bulldogs (27-7), who will play Utah on Saturday for a trip to the Sweet 16.

The key against Seton Hall (25-9) was limiting Isaiah Whitehead, the star of its run to its first Big East tournament title since 1993. He scored only 10 points and missed all 10 of his 3-point shots.

(3) Miami 79, (14) Buffalo 72

Angel Rodriguez had 24 points and seven rebounds as third-seeded Miami (26-7) held on to defeat No. 14 seed Buffalo 79-72.

Sheldon McClellan added 20 points and five rebounds. It is Miami's first tournament win since it went to the Sweet 16 in 2013.

The Bulls (20-15) finally got some traction, closing within 72-68 on a jumper by Lamonte Bearden with less than two minutes to play. But Miami hit enough free throws down the stretch to put the game away.

(9) Providence 70, (8) Southern California 69

Rodney Bullock hit a layup with 1.5 seconds left and Providence beat Southern California 70-69 on Thursday night.

Ben Bentil scored 19 points and Bullock finished with 16 points and 10 rebounds to help the ninth-seeded Friars (24-10) earn their first win in the tournament since 1997. They will face top-seeded North Carolina (29-6) on Saturday in the second round of the East Regional.

Jordan McLaughlin had 15 points for eighth-seeded Southern California (21-13), which missed the front ends of two one-and-ones in the final minute.

(11) Wichita St. 65, (6) Arizona 55

Fred VanVleet and Ron Baker combined for 29 points and Wichita State's swarming defence did the rest as the Shockers beat Arizona 65-55 on Thursday night.

Wichita State (26-8) will play Miami (26-7), the third seed in the South Region, on Saturday.

The Shockers forced 19 turnovers they converted into 22 points and snared nine steals against Arizona (25-9).

Arizona's big three of Ryan Anderson, Gabe York, and Allonzo Trier, each averaging 15 points, combined for 28.

(5) Indiana 99, (12) Chattanooga 74

Yogi Ferrell had 20 points and a season-high 10 assists, O.G. Anunoby pitched in 14 points and No. 5 seed Indiana took charge of its NCAA Tournament opener against Chattanooga on the way to a 99-74 victory in the East Region.

Thomas Bryant had 13 points and Troy Williams added 12 points and eight rebounds for the Hoosiers (26-7), who had their high-powered offence in prime form. They shot 37 for 57 from the floor for 64.9 per cent. Duke Ethridge had 16 points and Justin Tuoyo scored 12 points for the No. 12 seed Mocs (29-6).

(3) Utah 80, (14) Fresno St. 69

Sophomore seven-footer Jakob Poeltl scored 16 points and pulled down a career-high 18 rebounds to help Utah hold off feisty Fresno State 80-69.

Utah, the third seed in the Midwest, used a blistering 20-2 run down the stretch to regain control after falling behind for the first time all night with 10:32 remaining.

Lorenzo Bonham had 17 points and Brandon Taylor added 16 for the Utes (27-8), who will try for their second straight trip to the Sweet 16 when they face Seton Hall or Gonzaga on Saturday night. For the Bulldogs (25-10), it was their first NCAA appearance since 2001.

(4) Kentucky 85, (13) Stony Brook 57

Jamal Murray led five players in double figures with 19 points and fourth-seeded Kentucky routed Stony Brook 85-57 Thursday, setting up a showdown with rival Indiana in the second round of the NCAA Tournament.

Isaiah Briscoe scored 13 with 11 rebounds for the Wildcats (27-8), who haven't faced the Hoosiers since beating them in the Sweet 16 in 2012.

Jameel Warney had 23 points and 15 rebounds for Stony Brook (26-7), which was making its first NCAA Tournament appearance. The Seawolves, who shot 47.6 per cent entering play, was just 20 of 76 from the field.

(9) Connecticut 74, (8) Colorado 67

Connecticut is moving on to the second round of the South Region on the heels of a stellar showing at the foul line.

The No. 9 seed Huskies made 22 of 23 free throws to secure their 74-67 first-round victory over Colorado. That's the second-best single-game percentage, 95.7, in UConn history for a minimum of 15 attempts. The program record is 96.2 per cent, a 25-for-26 performance in 2003 against Rutgers.

The success should hardly have been a surprise. UConn is the best free-throw shooting team this season in country.

(4) Duke 93, (13) UNC Wilmington 85

Marshall Plumlee ditched the mask guarding his broken nose and responded by scoring a career-high 23 points to lead defending national champion Duke past UNC Wilmington 93-85.

Plumlee had 10 of his points and two blocks as the Blue Devils stepped up the defensive pressure early in the second half to build a lead after trailing at the break.

Duke (24-10), seeded fourth in the West, will next play Yale in the next round. UNCW (25-8), seeded 13th, was in it until the closing moments after Plumlee and Matt Jones fouled out.​

(4) Iowa State 94, (13) Iona 81

Iowa State has defeated Iona 94-81 to advance in the NCAA Tournament.

The fourth-seeded Cyclones (22-11) got 28 points from Georges Niang and will next face the winner of Thursday afternoon's game between Purdue and Little Rock.

Oh, and for those keeping track at home — or elsewhere — the 175 total points did surpass the over/under line in Vegas: 165.5.

(9) Butler 71, (8) Texas Tech 61

Kelan Martin scored all 11 of his points in the final 8½ minutes, including consecutive 3-pointers to break a tie game, to help Butler beat Texas Tech 71-61.

Kellen Dunham scored 23 points to lead the Bulldogs (22-10), including a critical 3 of his own with 2:26 left as the Midwest Region's No. 9 seed finally pulled away in the final minutes. Butler shot 52 per cent after halftime, using some NCAA Tournament experience to rally from an early eight-point deficit and finally push ahead midway through the second half.

Devaugntah Williams scored 18 points to lead the eighth-seeded Red Raiders (19-13), who were making their first tournament appearance since 2007.
