The Gamecocks are headed to their third consecutive College World Series final in Omaha, NE, after they beat Arkansas 3-2 Friday night.
The Razorbacks led South Carolina early in the game 2-0, but the Gamecocks rallied back with the help of strong pitching, several hits and runs from walks.
Pitcher Matt Price closed another strong game with a 1-2-3 in the 9th inning to hold onto the 3-2 lead for the win. Tyler Webb and Price combined for seven innings of shutout relief.
The Gamecocks (49-18) took the lead in the bottom of the seventh inning on Barrett Astin's two-out, bases-loaded walk to Adam Matthews.
The Gamecocks erased a 2-0 deficit in the fifth, with DJ Baxendale walking Christian Walker with the bases loaded to force in the tying run.
Matthews looked ready to swing on a 3-2 pitch from Astin in the seventh, but he held up as the slider dropped low and Joey Pankake trotted home for the going-ahead run.
Price (5-4) pitched three innings to earn his record fifth career win in the CWS. Colby Suggs (7-1) took the loss for Arkansas (46-22).
South Carolina will face Arizona, who remains unbeaten in Omaha, on Sunday. The winner of the best-of-three series will take home the College Worlds Series title, a potential three-peat for the Gamecocks.
The Gamecocks defeated UCLA in two games to win the title in 2010 and swept Florida in two games last year to win their second-straight crown.
The first game of the finals series is Sunday at 8 p.m. ESPN2 will carry the first game of the series before it moves to ESPN for game two on Monday and the "if necessary" game on Tuesday.
