Come help us celebrate World Softball Day as only SixFour3 can do. Whether you are a current SixFour3 member or new to our facility, we invite you to come out for a free, fun, interactive and competitive day focused on the great sport of softball. Join us for food, fun and competition. No appointments or scheduling needed, just show up and have fun. Your kids will enjoy our popular skills challenge, a free video swing analysis, an opportunity to demo the latest in softball technology from Louisville Slugger and DeMarini and the much anticipated, “dunk your trainer” (dunk tank). You and your kids will have an opportunity to use our facility free-of-charge, meet our trainers and interact with a number of our vendors. There is no registration required to attend the event but we would love to know if you plan on coming so we can plan accordingly. Please click here to RSVP if you intend to come.

About SF3:

SixFour3 is as a members-only, self-service indoor sports complex, designed for diamond sport athletes (currently softball only). Our facilities are divided into two distinct areas, one focused on individual member accommodations and the other on team and group training/clinics. With online booking options, innovative self-service training and an active trainers network, SF3 offers accommodations unlike any other. Add to that our state-of-the-art access control (including hands-free smartphone-powered access) and 24x7 video monitoring, our members enjoy anytime access in a highly secure environment.
