GAINESVILLE, Fla. (AP) — Nico Gramatica hit a 20-yard field goal as time expired and South Florida stunned No. 13 Florida 18-16 on Saturday to give the Bulls consecutive wins against ranked opponents to start the season.

Gramatica missed a 58-yarder with 2:52 remaining but got a chance to redeem himself after Florida defensive lineman Brandon Bett spit at a South Florida player on the Bulls’ next possession. Bett was ejected with a little more than two minutes to play, and the Bulls (2-0) got 15 yards and an automatic first down to spark an 87-yard drive.

It was the latest setback for embattled Florida coach Billy Napier, whose team is 1-1 for the fourth consecutive year.

The Gators looked as though they would rally after freshman Vernell Brown III returned a punt 40 yards to set up DJ Lagway’s lone touchdown pass. But the Gators flopped down the stretch, an all-too-familiar feeling during Napier’s tenure.

Napier’s play-calling was scrutinized as much as Lagway’s rehabilitated throwing shoulder, and the Gators found themselves trailing 15-9 in the fourth quarter following a defensive breakdown and a safety caused by a poor snap.

Poll implications

The Bulls will break into the AP Top 25 College Football Poll after upsetting then-No. 25 Boise State last week. The Gators surely will drop.

The takeaway

South Florida became only the third unranked team since 2000 to start 2-0 by beating two ranked teams, joining 2012 Oregon State and 2008 East Carolina.

Florida: The Gators have bigger issues than Lagway’s rust. Their offensive line allowed too much pressure and failed to create enough holes against USF.

Up next

South Florida: Plays at No. 5 Miami next Saturday, the Bulls’ third consecutive game against a ranked team.

Florida: Plays at No. 3 LSU next Saturday. The Gators last won in Baton Rouge in 2016.
