Each regional will be made up of four teams playing in a double-elimination format. All are scheduled from Friday through Monday. Regional winners advance to best-of-three super regionals, and those eight winners go on to the College World Series in Omaha.

Cross-state rival Georgia Tech also secured a Top 16 seeding and will host the Atlanta regional.
