About the Field Renovation

Excite Ballpark underwent a complete field renovation project to meet PDL standards in 2026. This project encompassed a new drainage system, irrigation system, off field vaulted manifold, pump system, sand base fusion rootzone, Duraedge infield with moisture rise, and Tahoma 31 Bermuda grass. To continue to be resource conscious Diamond Baseball Holdings has implemented Moisture rise and fusion rootzone. Moisture rise is a state-of-the-art subterranean infield watering system that allows moisture to be managed from the bottom of the infield column thus reducing man hours and overall water quantity. Fusion rootzone is a blend of sand and clay base soil that provides excellent infiltration and ideal porosity levels while also aiding in the retention of moisture and nutrients often lost in sand base athletic fields. New equipment was also purchased to support the maintenance of the new playing surface.
