The top-ranked Bulldogs had taken game one of the series against the 11th-ranked Rebels 6-3 Friday night, while Ole Miss got a Saturday win 10-8.
Scott Bittle (5-2) got the start and the win Sunday, pitching seven innings, allowing just a run on five hits with 11 strikeouts and a walk. David Goforth pitched the eighth and Jake Morgan the ninth, each facing three batters and allowing no baserunners.
The Bulldogs got a run in the top of the first inning on an RBI single by Friday night's Georgia hero, Joey Lewis, who launched a grand slam in game one to lift his team.
But the Rebels answered with two runs in the bottom of the first on a RBI single by Matt Snyder, which scored Jordan Henry who had reached on a base hit and stole second, and an error on the Bulldog right fielder on a fly ball by Kyle Henson, which scored Snyder.
An inside the park home run to the left field wall by Michael Hubbard in the third, disputed by Bulldog center fielder Matt Cerione and head coach David Perno, put the Rebels up 3-1. Cerione had raced back to the wall, appeared for a moment to have the ball, but fell to the ground as the umpire near third base and left field signaled no catch.
The Rebels broke the game open in the bottom of the sixth with three runs. With the bases loaded and one out, Henson headed home from third prior to an Evan Button bunt. The bunt was perfect, Henson scored, and Button reached safely.
With still just one out and the bases still full of Rebels, Henry singled up the middle to score two more runs and give the home team a three-run lead.
Bittle took care of the Rebels through seven, and then he turned it over to Goforth and Morgan.
"Another great baseball game that tops off another great weekend," Ole Miss head coach Mike Bianco said. "A tremendous effort by Bittle."
Georgia starter Justin Grimm, the first of four Bulldog pitchers, got the loss and is 2-3.
The Rebels, who outhit the Bulldogs 10-5, improved to 32-12 overall and 13-8 in Southeastern Conference play. Georgia fell to 33-11 and 14-7.
The Bulldogs are tied with LSU for the overall conference lead. The Rebels are tied for fourth with Florida, half a game behind Arkansas which is 13-7.
Ole Miss, which plays three games at Auburn this weekend, has two midweek games upcoming. The Rebels play Southern Mississippi at Pearl Tuesday night and host Arkansas-Pine Bluff Wednesday night.
