The Mariners will play host to several teams visiting from across Ireland on Saturday, 20 June, with both youth and adult league games on three different diamonds.
Mariners Field at Charlesland will be divided into two youth diamonds for U13 league games (starting at 10.30 am) between the Mariners, Cavan Comets, Kerry Green Sox, Cork Druids, Clondalkin Cardinals and Portstewart Eagles.
Up above the Charlesland Sport and Recreation Park on the top soccer pitch, the Mariners adult team will take on the Dublin Hurricanes in an A-B double header, also starting at 10.30.
With sunshine in the forecast and 8 baseball teams converging on Greystones, there is no better time to soak up some good Irish baseball.
