The Facility

Our 8,500 square foot facility is dedicated to the improvement of our Warriors baseball players. We have 8,500 square feet completely covered in top of the line field turf. This is the same field turf used in professional sports and universities.


We invested in this field turf to help prevent sports injuries caused by training in traditional "carpeted" facilities, which provide very little cushion from the cement floors.


We use the top of the line "Illuminator" batting cages. Our facility has batting cages, indoor infield practice space, pitching lanes, and high ceilings with 100' field length to accomodate our indoor throwing programs.
