NEW YORK — With 4 seconds left in overtime, Chris Chiozza took off, hoping to get to the hoop or find an open man. Instead, the Florida point guard stopped short right at the 3-point line and let fly with a shot that will go down in Gators’ history.

Chiozza’s 3-pointer swished in at the buzzer in to give Florida an 84-83 victory against Wisconsin on Friday night in the first overtime game of this NCAA Tournament.

Nigel Hayes had given the Badgers (27-10) a 2-point lead with 4 seconds left on two free throws. With no timeouts left, the Gators inbounded to Chiozza and he took care of the rest for Florida (27-8), setting off a celebration under the basket at Madison Square Garden.

“I was going to pass, but I was really going to the rim. But they did a good job of bumping me and slowing me down, and that was the shot I had so I had to have that one,” Chiozza said.

Wisconsin’s Zak Showalter was all set to be the star before Chiozza took it away. Showalter, a senior and former walk-on, forced overtime with a leaning 3-pointer off one leg with 2.1 seconds left in regulation as the Badgers wiped out a 12-point, second-half deficit in the last 4:15.

The fourth-seeded Gators will play South Carolina on Sunday in an all-Southeastern Conference regional final. Florida is in the Elite Eight for the first time since 2014, and for the first time with second-year coach Mike White — the former Mississippi guard who was on the losing end of one of the most famous game-winning shots in NCAA history.

South Carolina 70, Baylor 50

NEW YORK (AP) — Sindarius Thornwell scored 24 points and seventh-seeded South Carolina cruised past third-seeded Baylor 70-50 on Friday night in the East Regional semifinals, the Bears’ worst NCAA Tournament loss.

The Gamecocks (25-10) were in control from the middle of the first half on, mixing defenses and hustling all over the Madison Square Garden court to advance to the Elite Eight for the first time.

South Carolina will meet the winner of the Wisconsin-Florida game on Sunday with a trip to the Final Four at stake.

DJ Dozier and Chris Silva had 12 points each and Duane Notice added 11 for the Gamecocks.

Johnathan Motley had 18 points, 12 in the second half, for Baylor (27-8), which just couldn’t get any offense going. The Bears missed 11 of their first 13 shots from the field and it didn’t get a whole lot better the entire game. They finished 17 for 56 from the field (30.4 percent), including 3 for 13 from 3-point range.

South Carolina opened the second half on a 12-6 run to get the lead to 49-28. The largest lead was 63-41.

Baylor was able to close to 11 points but that was as tight as the game would get.

The Gamecocks went on a 16-0 run that lasted 7:44 in the first half. They turned a 15-15 tie into a 31-15 lead with 2:50 left in the first half. The Bears went 0 for 10 from the field and committed four turnovers in the run. South Carolina’s biggest lead of the half was 37-20 on a 3 by Notice with 29 seconds to play. It was 37-22 at halftime.

The Bears shot just 25 percent from the field in the first half (8 of 32) and committed seven turnovers.

UNC 92, Butler 80

MEMPHIS, Tenn. — Joel Berry II scored 26 points and Justin Jackson added 24 as top-seeded North Carolina moved to the Elite Eight with a 92-80 victory over Butler in the NCAA South Region on Friday night.

Luke Maye recorded his first career double-double with 16 points and 12 rebounds, helping fuel a quick start for Carolina (30-7). The Tar Heels never let their lead get under double digits in the second half.

Andrew Chrabascz led the fourth-seeded Bulldogs (25-9) with 21 points and seven rebounds, while Kelan Martin finished with 16 points for Butler, which struggled shooting early and did not recover.

Carolina, which reached the Elite Eight for the 27th time, will face the winner of Friday’s second game between UCLA and Kentucky. The Tar Heels connected on 54.4 percent of their shots, while Butler was at 43.5 percent.

Kentucky 86, UCLA 75

MEMPHIS, Tenn. — De’Aaron Fox scored a career-high 39 points as the Kentucky Wildcats beat UCLA 86-75 Friday night in a showdown between two of college basketball’s goliaths for a spot in the South Regional final.

The only No. 2 seed to advance to the Elite Eight, the Wildcats (32-5) won their 14th straight game. Now the NCAA’s winningest program will play another of basketball’s titans Sunday in top-seeded North Carolina with a trip to yet another Final Four on the line.

The third-seeded Bruins (31-5) still have the most national titles. Yet they leave their third Sweet 16 under coach Steve Alford short of the Elite Eight.

Fans lustily booed Kentucky coach John Calipari in his first game in Memphis since leaving in April 2009 for the Wildcats. Calipari’s latest crop of talented freshmen put Kentucky into a regional final for the sixth time in seven years.

Malik Monk scored 21 points for Kentucky, and Dominique Hawkins added 11.
