"It's amazing what these kids continue to do," Georgia coach David Perno said.
"In an elimination game, after that start, I thought it was going to be a struggle all day."
The fourth-largest crowd in Foley Field history, 3,937, took in the action on a day when the temperature at first pitch was 97 degrees.
Georgia's victory forced a deciding Game 3 today at 7 p.m. The game will be televised on ESPN2.
Today's winner will earn a berth in next week's College World Series. The loser's season will be through. Georgia is looking for its fifth appearance all-time in the CWS, while South Carolina is shooting for four in the last five years.
The seventh-seeded Bulldogs (46-21) forced today's game by winning their fourth straight elimination game in this NCAA Tournament. They are 10-0 all-time in Foley Field in NCAA elimination games. "They've got a pretty good run going," South Carolina coach Ray Tanner said, "but maybe they're due to stumble."
Since April 26, the Bulldogs are 22-5 overall, including 7-1 in conference and NCAA elimination games.
"That's the more important number," Perno said. "That tells the story about this group of guys."
Georgia's season was in serious peril after three innings. The Gamecocks, who bludgeoned the Bulldogs 15-6 on Saturday, started the day by building a 4-0 lead thanks to a series of mistakes by Georgia, including a two-out throwing error by third baseman Ryan Peisel that led to three first-inning runs for the Gamecocks.
However, by the end, Georgia had amassed 19 hits and scored 11 runs despite leaving 12 men on base. Every Georgia starter except Kyle Keen had a hit, and Jonathan Wyatt, Joey Side, Josh Morris and Peisel all had three-hit games.
Side tied the school record for hits in a season (108) and broke the school record for total bases in a season (182).
The Bulldogs showed their first signs of life this weekend in the top of fourth. Morris led off with a double, and senior right fielder Bobby Felmy followed with a single to score Morris. Jacobs then hit a two-run home run, just his seventh of the season, over the left field wall to pull Georgia within one at 4-3 and enliven the home fans for the first time in the series.
"I guess when there's no tomorrow, you have to step up and do something," Jacobs said.
Keen and Peisel followed Jacobs by reaching on a walk and single, respectively. Second baseman Matthew Dunn tied the game with a sacrifice bunt that scored Keen, and Peisel scored on a wild pitch by South Carolina starter Mike Cisco to take the lead for good.
"I made a couple mistakes and then they had the momentum, and that was that," said Cisco, who fell to 7-5 after giving up seven hits in three innings.
Meanwhile, Georgia starter Brooks Brown rebounded from Peisel's first inning error to improve to 8-4 this season.
"As soon as he got that (five-run inning), he was a whole different guy out there," South Carolina designated hitter Phil Disher said.
Brown, plus relievers Rip Warren and Joshua Fields, allowed just one South Carolina hit after the third inning.
