It wouldn't be a Southern Conference softball tournament without Georgia Southern and Chattanooga meeting at least once. The 2013 tournament opens today in Greensboro, N.C., and the rivals will meet at 2:30 p.m., in the first round of the double-elimination bracket. "It's a rivalry, and it's been a good rivalry for a long time," GSU coach Annie Smith said about the matchup with the Mocs.
