COLUMBIA, S.C. -- Tight end Jace Sternberger knew plenty of people were waiting for No. 22 Texas A&M to fall apart after its surprisingly strong start.
The Aggies showed Saturday they're not going away any time soon.
Sternberger had heard too many comparisons with past Aggies teams who opened strong, then faded as the Southeastern Conference season wore on.
"We put a lot of pressure on ourselves this week," he said. "We knew everybody was waiting to see how we were going to respond."
The Aggies answered with a winning final quarter after squandering a 16-0 second-half lead.
"We were going to get over that hump and we were able to show that today," he said.
There are several more tests ahead for Texas A&M (5-2, 3-1), including road games with Mississippi State and Auburn and closing the regular season against LSU.
For now, though, the Aggies displayed the grit and resolve essential to succeed in the SEC.
"We've got some guys with heart and toughness, I can you that," first year Texas A&M coach Jimbo Fisher said.
The Aggies won their third straight this season and moved to 5-0 against the Gamecocks (3-3, 2-3) since joining the league in 2012.
Mond also had a 4-yard touchdown pass to Sternberger in the second quarter and, when Small hit a 32-yard field goal on the Aggies' first drive of the second half to go up 16-0, it looked like more than enough to put away the Gamecocks, who managed just 102 yards of offense the first 30 minutes.
That's when Jake Bentley, returning after missing last week's win over Missouri with a knee injury, led a pair of third-quarter TD drives -- and the two-point conversions both times.
Bryan Edwards caught both two-point tries, stretching second across the line before falling out of bounds to tie the game.
Texas A&M responded with the winning drive next time out, moving 45 yards to set Small up for a 39-yard field goal with 9:16 left.
The Aggies sealed things with Trayveon William's 3-yard scoring run with 1:36 left.
South Carolina got a final TD pass from Bentley to Samuel with 48 seconds to go, but could not execute an onside kick attempt. Texas A&M ran out the clock.
Mond got the Aggies going when he found his big tight end Sternberger. The 6-foot-4, 250-pound junior had a 53-yard reception where he dragged safety Steven Montac (some 65 pounds lighter) about 25 yards inside the South Carolina 10.
Asked if he'd ever carried a player that far, Sternberger joked, "Just my little brother."
Small opened Texas A&M's scoring with a 52-yard field goal, the freshman tying his career long kick.
South Carolina struggled with Bentley back behind center in the opening half. The junior, talked about at times this season as an NFL prospect, was 6 of 17 passing the first 30 minutes for 46 yards. He had an awful interception in the end zone to kill off the Gamecocks best scoring chance of the half.
"We didn't take advantage of opportunities," South Carolina coach Will Muschamp said.
Mond was 25 of 37 passing. His 353 yards was the second most of his career after throwing for 430 yards in a 28-26 loss to No. 4 Clemson last month.
TEXAS A&M: The Aggies have found ways to hang in games and overcome opponents at the end. It happened a week ago in a 20-14 overtime victory against previously undefeated Kentucky. And they did it against the Gamecocks when momentum had switched in South Carolina's favor.
SOUTH CAROLINA: The Gamecocks played another in a series of terrible first halves. Bentley had only nine yards passing two weeks ago at Kentucky the first two quarters and South Carolina trailed 23-14 at the break against Missouri before rallying. The Gamecocks must figure out a way to start faster or risk more such defeats this season.
Texas A&M punter Braden Mann, who led the Football Bowl Subdivision with a gross average of 54.9 yards coming in, had a long of 67 yards against the Gamecocks. He also caused a fumble with a hit on South Carolina returner Bryan Edwards. "He can sell popcorn, too," Aggies coach Jimbo Fisher said.
Two members of Texas A&M's secondary were ejected for targeting. Cornerback Debione Renfro was ejected in the first quarter while safety Donovon Wilson was thrown out in the final period. Fisher said he'll continue strongly reminding his players the right way to tackle.
Texas A&M is off next week and plays at Mississippi State on Oct. 27.
South Carolina is off next week and returns to play Tennessee at home on Oct. 27.
