Wes Hodges led off with a  homer and Michael Brantly drove in Jason Donald to tie the game in the ninth.

G-Braves catcher Clint Sammons was 1-for-4 with a two-run homer in the fifth. Columbus got both runs back in the bottom of the frame. After Barton, who was pinch running for Alvin Colina, scored the deciding run, J.C. Holt put Gwinnett up 4-2 when he scored on a single by Reid Gorecki.
