The opener at LaFayette High School saw the Tennessee girls get a buzzer-beating 3-pointer to tie the game at the end of regulation before pulling away in overtime for a 85-78 victory.
In the nightcap, the two squads combined for 22 3-pointers before Team Georgia came away with a 94-89 win.
The girls contest looked like a runaway early as Tennessee used a 14-4 burst in the second quarter to help open up a 48-33 lead at intermission.
The lead grew to 17 points midway through the third quarter when the Georgia offense awoke.
Spurred by Chattoogas Jheri Booker and the Northwest Whitfield trio of Vanessa Jackson, Brinkley Knowles and Larkin Logan, the Peach State stormed back to take a 72-71 lead on a Logan lay-up with a little under a minute to play.
Georgia would tack on a pair of free throws to take a 3-point lead with 6.8 seconds left, but it turned out to be plenty of time for Chattanooga Christian All-Stater Juanisha Hansford.
The Mercer University signee drained a 25-foot trey to beat the buzzer and send the game into overtime.
In the extra frame, Tyners Katrich Williams and Brainerds Nakisha Strickland combined for seven of Tennessees 11 points to give the Volunteer State a 3-1 lead in the series.

The boys game saw Tennessee jump out to a 48-43 halftime lead before scoring the last seven points of the third quarter to go ahead 75-66.
But Georgia MVP Stephen McClellan would make his presence known in the fourth quarter.
McClellan, who scored over 3,600 career points at Daltons Christian Heritage School, poured in 15 of his All-Star record 26 points in the final eight minutes. He was a perfect 5-of-5 at the line in the fourth, including four big shots late, to help seal the win and even the series at two wins apiece.
Southeast Whitfields Nic White had a big game with 20 points and a record nine rebounds.
LaFayette big man Matt Overby was solid with 12 points and five boards. Teammate Taylor Sumrall scored just five points, but played outstanding defense with four rebounds, two steals and two key second-half blocks.
Tennessee put five in dou-ble figures led by McMinn Centrals Blake Derrek. Derrek had 16 points to garner Tennessee MVP honors.
