Nico Gramatica nailed a 20-yard field goal as time expired as South Florida rallied to stun No. 13 Florida 18-16 on Saturday in Gainesville, Fla.

After beating then-No. 25 Boise State in Week 1, the Bulls (2-0) went 87 yards in eight plays in the final two minutes to set up Gramatica's third field goal.

It was USF's second straight win over an AP ranked team and first on the road since beating Notre Dame in 2011.

Gramatica missed a 58-yarder just short with 2:52 left that would have put the Bulls up.

USF signal-caller Byrum Brown was 23 of 36 for 263 passing yards and a touchdown, while Florida's DJ Lagway was 23 of 33 for 222 yards with a TD and an interception.

No. 1 Ohio State 70, Grambling 0

Quarterback Julian Sayin had a near perfect game when the Buckeyes pounded the Tigers in Columbus.

Sayin, in his second career start, set a school record for consecutive completions to start a game (16) and through two quarters was 18 of 19 for 306 yards and four touchdowns. Two went to Jeremiah Smith, including an 87-yarder as the Buckeyes cruised to a 35-0 lead. Sayin, Smith and many of the starters did not play in the second half.

The Tigers (1-1), an FCS school, were no match for the Buckeyes (2-0) and Sayin was 10-for-10 for 218 yards with three touchdowns in the first 10:50 of the game.

No. 2 Penn State 34, Florida International 0

Drew Allar completed 19 of 33 passes for 200 yards and two touchdowns, and Kaytron Allen and Nick Singleton each rushed for a touchdown to lead the Nittany Lions over the visiting Panthers.

Khalil Dinkins and Devonte Ross each caught a touchdown pass for Penn State (2-0), and Ryan Barker made two field goals. Allen carried the ball 16 times for 144 yards. His touchdown came on a 67-yard run with 3:29 to play. Singleton gained 76 yards on 13 carries; he scored on a 5-yard run with 1:19 left.

FIU (1-1) turned the ball over twice and was limited to 149 passing yards. The Panthers were 6 of 18 on third down.

No. 3 LSU 23, Louisiana Tech 3

Garrett Nussmeier threw a touchdown pass and Caden Durham rushed for a touchdown in an otherwise sluggish offensive performance as the Tigers defeated the Bulldogs in Baton Rouge, La.

The Tigers (2-0) were favored by more than five touchdowns, but didn't build a comfortable lead until late in the third quarter. But a dominant performance by the LSU defense prevented any serious threat of an upset. Nussmeier completed 26 of 41 passes for 237 yards, but threw an interception on the game's first possession, setting the tone for the defense-oriented game.

Trey Kukuk completed just 12 of 18 passes for 50 yards and the Bulldogs (1-1) finished with 58 rushing yards and 154 total yards. The Tigers ran 22 more plays than Louisiana Tech (75-53), leading to a 36:52-23:08 advantage in time of possession and they allowed an average of just 2.9 yards per play.

No. 4 Georgia 28, Austin Peay 6

Nate Frazier and Chauncey Bowens each scored two touchdowns to lead the host Bulldogs to a win over the Govs. The game's start time was moved up an hour to avoid inclement weather, but lightning in the area forced a two-hour delay at halftime.

Georgia's defense held the Governors to 45 yards rushing, while Gunner Stockton completed 26 of 34 passes for 227 yards as Georgia (2-0) converted seven of 13 third downs. Frazier carried the ball 14 times for 69 yards, while Colbie Young caught seven passes for 76 yards.

For Austin Peay (1-1), Chris Parson finished 16-for-23 passing for 151 yards and one interception. Corey Richardson was their leading rusher, carrying the ball seven times for 33 yards.

No. 5 Miami 45, Bethune-Cookman 3

Carson Beck completed 22 of 24 passes for 267 yards and threw a pair of touchdown passes as the Hurricanes took care of business with a victory over the Wildcats at Miami Gardens, Fla.

The Hurricanes (2-0) improved to 8-0 lifetime against the Wildcats (0-2), who were held to a Juan Dominguez 32-yard field goal and have yet to score a touchdown this season. Bethune-Cookman quarterback Timmy McClain completed 13 of 15 passes for just 86 passing yards.

Beck completed his first 15 passes, breaking the program record of 14 in a row to start a game set by Vinny Testaverde against Oklahoma in 1986. Beck and backup quarterback Emory Williams completed passes to 14 different receivers.

No. 6 Oregon 69, Oklahoma State 3

In another dominant offensive showing, the Ducks cleaned house and sent the Cowboys packing with a dominating win in Eugene, Ore.

The Ducks (2-0) once again came out firing on all cylinders, scoring touchdowns on six of their seven first-half drives and finishing with 631 total yards. Dante Moore finished with 266 yards passing, completing 16 of his 21 passes to go with three touchdowns.

Oklahoma State (1-1) had just three drives that lasted longer than four plays, and had fewer first downs (9) than Oregon had total touchdowns (10).

No. 7 Texas 38, San Jose State 7

Arch Manning passed for 295 yards and four touchdowns and ran for another score to fuel the Longhorns to a victory over the Spartans in Austin.

Texas (1-1) bounced back from a season-opening loss at now top-ranked Ohio State with a dominating performance from its ball-hawking defense, which forced three fumbles (two by preseason All-American linebacker Anthony Hill) and an interception. Parker Livingstone posted 128 receiving yards and two touchdown receptions.

Walker Eget passed for 188 yards to pace the Spartans (0-2). They got on the scoreboard with a 4-yard touchdown run by Jabari Bates.

No. 8 Clemson 27, Troy 16

Cade Klubnik threw two touchdown passes in the second half to rally the Tigers to a victory over the visiting Trojans in a game that was delayed for 90 minutes in the first half because of a lightning storm.

Adam Randall carried 21 times for 112 yards and a touchdown as Clemson (1-1) overcame a 16-point deficit against the Sun Belt Conference squad, which was gunning for its first-ever upset of a top-10 team. Klubnik completed 18 of 24 passes for 196 yards and one interception. But after hearing boos in the first half, Klubnik fired both of his touchdown passes to Bryant Wesco Jr., who finished with seven receptions for 118 yards.

Goose Crowder completed 19 of 31 passes for 223 yards and a touchdown for Troy (1-1), but his three interceptions were costly.

No. 10 South Carolina 38, South Carolina State 10

Vicari Swain returned a pair of second-quarter punts for touchdowns, helping the Gamecocks overcome a slow start and pull away with a win over the Bulldogs in Columbia, S.C.

With South Carolina facing a 3-0 deficit, Swain returned a punt 65 yards for a touchdown to get the Gamecocks on the board with 5:01 left in the first half. Less than two minutes later, he again housed a punt, this one a 42-yard return after it was partially blocked, to make it 14-3 over the Bulldogs

LaNorris Sellers was 11-for-19 (57.9 percent) for 128 yards with 23 rushing yards on eight carries. SC State QB William Atkins IV got the start and completed 10 of 14 passes for 118 yards. He was replaced in the third quarter by Ryan Stubblefield, who was 8 of 14 for 90 yards and a touchdown.

No. 11 Illinois 45, Duke 19

Luke Altmyer went 22 of 31 for 296 yards and three touchdowns as the visiting Fighting Illini pulled away from the mistake-prone Blue Devils.

Altmyer's main target was Hank Beatty, who caught eight passes for 128 yards for the Fighting Illini (2-0). Beatty also had a 25-yard scoring run. Cole Rusk, Justin Bowick and Collin Dixon had TD receptions while Kaden Feagin and Ca'Lil Valentine added rushing TDs.

Duke's Darian Mensah was 23 of 34 for 334 yards, an interception and two scores to Andrel Anthony. Yet the Blue Devils (1-1) turned the ball over five times, committed very costly penalties and were outscored 31-6 in the second half.

Mississippi State 24, No. 12 Arizona State 20

Blake Shapen tossed a 58-yard touchdown pass to Brenen Thompson with 30 seconds left to give the Bulldogs a victory over the Sun Devils at Starkville, Miss.

The Mississippi State defense put together a stellar goal-line stand to hold Arizona State to a field goal before the big play in which Thompson found operating room and caught Shapen's pass inside the 25-yard line and dashed into the end zone. Shapen completed 19 of 33 passes for 279 yards and three touchdowns for Mississippi State (2-0).

Raleek Brown rushed for 110 yards on 18 carries and Kanye Udoh had 105 yards and one score on 23 carries for Arizona State (1-1). Sam Leavitt was 10-of-22 passing for just 82 yards and was intercepted twice. He also threw a touchdown pass to Jordyn Tyson.

No. 14 Florida State 77, East Texas A&M 3

The Lions (0-2) got on the board with a 21-yard field goal from Ozlo Rigby with 9:32 left in the game.

No. 18 Oklahoma 24, No. 15 Michigan 13

John Mateer threw for 270 yards and a touchdown and ran for 74 yards and two more scores as the Sooners beat the Wolverines in Norman, Okla.

The Sooners (2-0) outgained the Wolverines (1-1) 408-288, making life difficult for Michigan freshman quarterback Bryce Underwood (9-of-24 passing, 142 yards) in his first road start. Oklahoma held Michigan to just 3-of-14 third-down conversions.

Mateer played like a quarterback with plenty of experience, finishing 21-of-34 passing with one interception.

No. 16 Iowa State 16, Iowa 13

Kyle Konrardy kicked a 54-yard field goal with 1:52 remaining to give the Cyclones (3-0) their first Cy-Hawk Rivalry home win over the Hawkeyes (1-1) since 2011 in Ames, Iowa.

The Cyclones held a 238-214 edge in total offense in a contest controlled by the defenses. Rocco Becht completed 18 of 27 passes for 134 yards and one touchdown for the Cyclones. Benjamin Brahmer caught the scoring pass.

Mark Gronowski was just 13-of-24 passing for 83 yards and one interception for the Hawkeyes. The South Dakota State transfer also had 37 yards and a score on the ground that helped erase a 10-point first-half deficit.

Baylor 48, No. 17 SMU 45 (2OT)

Facing a 14-point fourth-quarter deficit, the Bears surged back to stun the Mustangs in double overtime in Dallas, winning their 13th straight game in the in-state series when Connor Hawkins hit a 27-yard field goal in the second overtime after SMU's Collin Rogers missed his kick.

SMU (1-1) running back T.J. Harden racked up 115 yards on the ground with three scores, two of which came in the opening seven minutes of the fourth quarter to break a 24-24 deadlock.

No. 19 Texas A&M 44, Utah State 22

Marcel Reed delivered his second stellar performance so far this season, throwing three touchdown passes and rushing for another to lead Texas A&M to a home victory over Utah State.

Reed completed 19 of 28 passes for 220 yards; he also ran for 66 yards on 10 carries. However, he appeared to suffer an injury after being tackled on a run late in the third quarter. He remained down on the field while being attended to by the Aggies' medical staff; after a couple of minutes, he was seen walking briskly into the locker room.

Utah State battled in the second half and outscored the Aggies 16-14, scoring on two touchdown passes from quarterback Bryson Barnes, who completed 15 of 30 passes for 169 yards.

No. 20 Ole Miss 30, Kentucky 23

Aidan Armenta completed 8 of 14 passes for 28 yards and one interception for the Warhawks (1-1). UL Monroe allowed 583 yards and gained just 148.

Germie Bernard caught two touchdown passes and Isaiah Horton, Kaleb Edwards, Josh Cuevas, Cole Adams and MJ Chirgwin each had one scoring catch as the Crimson Tide built a 42-point halftime lead.
