Been away from following the SAA for a number of years, but I took a look and it looks like Berry came up over the past few years and Oglethorpe recently hired the coach that seemingly built up that program.
Birmingham-Southern, Millsaps, and Hendrix were the powerhouse baseball programs historically that could compete on a national level, but I think in recent years Rhodes has been more competitive and I noticed Berry the past 4 years. Birmingham is typically nationally ranked year in and year out.
