SAVANNAH — The phrase is written across the backs of the North Hall baseball team’s shirts, plastered on signs surrounding Jody Davis Field in Gainesville and on the lips of the Trojans every time they break a huddle. “Leave No Doubt” — the team’s slogan this season — became more of a way of life than a rallying cry, coach Trent Mongero explained. It applied to his players on both the individual and team levels, a reminder to always put forth the best effort possible and prove wrong anyone who questioned what they were capable of.
