PARADISE ISLAND, Bahamas — All D'Vauntes Smith-Rivera wanted to do was get to his spot.
The rest was just instinct.
Smith-Rivera made a jumper with 3.4 seconds left in overtime, and Georgetown got a wild 66-65 victory over No. 18 Florida on Wednesday night in the Battle 4 Atlantis quarterfinals.
It was the 21st and final lead change of the night, and sent the Hoyas (4-0) into Thursday's semifinals against No. 2 Wisconsin.
"The team sitting in front of us tomorrow is a monster," Hoyas coach John Thompson III said.
Added Smith-Rivera: "We're a monster too."
If nothing else, the Hoyas have to be steeled by a game with tons of twists and turns.
Kasey Hill's three-point play with 11.5 seconds left put the Gators (2-2) up by one, but Smith-Rivera connected from near the top of the key for what became the winner.
Smith-Rivera led all scorers with 17 points. Paul White and Jabril Trawick each added 10 for Georgetown.
"This felt like a middle-of-the-season, end-of-the-season game," Thompson said. "That was two teams going back and forth at each other. ... It was a good game for us to be in now, it was a good game for them to be in now."
Dorian Finney-Smith scored 16 points, Michael Frazier II added 12 and Jon Horford had 10 for Florida, which shot just 36 percent.
"We don't play the right way. We don't play the right way. We don't," Gators coach Billy Donovan said. "I would say this: We're not an overly talented team and we don't have a lot of size. We're a team that can be a hard-working team, can be an unselfish team, but we need to pass and share the basketball.
"I would say our basketball acumen needs to get a lot better," Donovan added. "There's not a great feel sometimes with decisions that we make."
Both teams came up empty at the end of regulation. Trawick fouled out with 34.1 seconds left when he charged into Florida's Jacob Kurtz, and Eli Carter tried to win it for the Gators at the buzzer but failed to get a decent shot off in the lane against a slew of defenders.
The Gators — still very much a work in progress because of serious roster shuffling — had to get creative against Georgetown center Joshua Smith, sometimes even using the 6-foot-6, 210-pound Kurtz against the 6-foot-10, 350-pound Hoya.
Smith was more than willing to help their cause. He was called twice for flagrant fouls after reviews showed him leading with his elbow, including one with 7:07 remaining in regulation where Kurtz got sent flying.
Kurtz made one of the two ensuing free throws for that one, putting the Gators up 44-42. Georgetown answered with the next six, and the frantic finish was on the way.
"We came up one play short," Kurtz said.
Georgetown: The Hoyas led 31-27 at the half despite having no one score more than six points in the opening 20 minutes. ... Georgetown freshman reserve C Trey Mourning — son of Basketball Hall of Famer Alonzo Mourning — was at least relatively close to home for his first Thanksgiving as a collegian, with the Bahamas about 30 minutes by plane from Miami. ... The Hoyas were playing away from home for the first time this season.
Florida: This is the first time since the 1949-50 season that the Gators haven't scored at least 70 points in any of their first four games. ... No Gator started warming up for the second half until 2:25 remained on the halftime clock. ... It was the 101st time that Donovan coached a team in November. Those teams are now 89-12.
For the first time since 2006, Florida and Georgetown finished with they started. They last met in 2012 on the deck of the USS Bataan, when the game was called at halftime because of on-court condensation and with the Gators leading 27-23. They last played a full game in the 2006 NCAA Tournament, when the Gators won 57-53 on the way to the national title.
Boston Celtics President of basketball operations Danny Ainge was in the crowd, as were scouts from several NBA teams, including the reigning champion San Antonio Spurs.
Georgetown: Faces No. 2 Wisconsin in Thursday's semifinals.
Florida: Faces Alabama-Birmingham in Thursday's consolation round.
