Buchholz, who starred on the Tiger soccer team this fall, had missed two earlier field-goal attempts. But he nailed the one that counted most and his teammates leaped in celebration at Williams-Brice Stadium.
Clemson (9-3) is 9-1 on South Carolina's home field since 1989.
For Spurrier and South Carolina (6-6), the defeat was their fifth straight, and it leaves the Gamecocks with precarious postseason hopes.
A month ago, South Carolina seemed a sure bet at the postseason at 6-1 and No. 6 in the country.
The Gamecocks looked ready to end the skid in this one, overcoming Clemson's 17-7 lead to go ahead 21-20 with 9 minutes left on the last of Blake Mitchell's three TD throws.
However, Clemson quarterback Cullen Harper guided the Tigers into position. He found Aaron Kelly with a 12-yard pass on fourth-and-4. The two connected again moments later on an 18-yard pass to South Carolina's 16.
That's when Buchholz calmly hit the game-winner. A week ago, Buchholz was short on a 54-yarder at the end that would've tied things in the Tigers' 20-17 loss to Boston College that cost them a chance at the Atlantic Coast Conference title.
Harper finished 28 of 38 for 229 yards and his 27th touchdown pass.
James Davis rushed for 122 yards on 23 carries, while C.J. Spiller had 88 yards.
