With a rich history of multiple ISST Championships, ISB Baseball is alive and healthy. The Lower Field has a dedicated baseball diamond/field including flood lighting.
Varsity - The Varsity baseball team practises three times a week. ISB Varsity baseball will host and travel according to ISST rules and regulations, so players selected for the team are expected to accept visiting team members into their homes. They will also take part in an ISST at the end of the season.
JV Baseball - Numbers permitting, ISB runs a JV baseball programme and like most ISB JV squads they will travel and also be expected to welcome visiting athletes into their homes. The JV team usually practises twice a week after school.
