Alvaro Folgueiras drilled a 3-pointer with 4.5 seconds remaining to lift ninth-seeded Iowa to a 73-72 victory over top-seeded Florida on Sunday in the second round of the NCAA Tournament. The loss sent the defending champions home and marked the first elimination of a No. 1 seed in this year’s tournament.

Under first-year head coach Ben McCollum, Iowa (23-12) advanced to the Sweet 16 for the first time since 2015. Florida finished its season 27-8.

The Hawkeyes built a double-digit lead in the second half but saw it slip away late as Florida surged ahead in the final minutes. A layup by Xaivian Lee gave the Gators a 71-68 lead with under two minutes remaining. Bennett Stirtz responded with a floater to cut the deficit to one with under a minute to play.

After a missed Florida 3-pointer and a series of rebounds, Iowa regained possession in the closing seconds. The Hawkeyes broke Florida’s full-court press, leaving Folgueiras open in the corner for the go-ahead shot. Florida failed to get a final attempt off before the buzzer.

Tavion Banks led Iowa with 20 points on efficient shooting, while Folgueiras added 14, including the game-winner. Stirtz contributed 13 points and five assists, helping guide the offense despite a tough shooting night.

Iowa set the tone early by attacking the paint and controlling the glass, building a first-half edge and maintaining pressure throughout. The Hawkeyes also found key perimeter shooting in the second half, including a strong stretch from Cooper Koch that helped extend their lead before Florida’s late push.

The victory marks one of the biggest upsets of the tournament so far, with Iowa overcoming the defending champions in dramatic fashion to continue its postseason run.
