A run-scoring double by Rich Poythress in the 10th inning gave Georgia the lead for good in a 4-2 victory over Vanderbilt on Saturday at Hawkins Field.
The 11th-ranked Bulldogs can win the regular-season Southeastern Conference championship by beating the 18th-ranked Commodores on Sunday in the final game of the series. First pitch is 1 p.m.
Georgia improved to 31-17-1 overall and 18-7-1 in SEC play, while Vanderbilt dropped to 37-14 and 15-10.
Trailing 4-2 in the bottom of the 10th inning, Vanderbilt put two runners on base against ace Georgia closer Joshua Fields, but Ryan Flaherty struck out to end the game.
The Commodores led 2-0 entering the ninth inning before the Bulldogs rallied, scoring two runs to send the game into extra innings.
"Going into the ninth with a two-run lead, you are just not safe against a good hitting team like Georgia," Vanderbilt coach Tim Corbin said. "We just didn't finish the game."
Dean Weaver [4-1] picked up the win in relief. VU reliever Russell Brewer [4-1] took the loss. Vanderbilt starter Caleb Cotham allowed no runs and struck out seven in seven innings.
David Macias and Alex Feinberg led the Commodores with two hits each, while Pedro Alvarez hit his sixth home run of the season.
Ryan Peisel and Gordon Beckham each had two hits to lead Georgia.
