Music, buddies, and a real team.

- No cost. Uniform shirts and hats with team logos included.
- All games at Harrison Park.
- SPBA 12U rec teams help at games, joined by other community organizations.
- Volunteers are always needed — time and talent welcome.
Whether it’s the confidence of hitting a ball, running the bases, dancing, or belonging to a team, our players leave with achievement and joy.
Facilities

Field status lives on Statusfy — not buried mid-page. Sign up for real-time alerts, scan the QR on the current site, or check now. Coaches also use the field scheduler and should release unused practice slots.
Park investments
SPBA has put real money and labor into these parks: $70,000 toward Sweat renovations, Harrison Field 5 cages, Field 6 under-drain, movable mound pads, ABI Force, Gator and tractor, windscreens, dugout roofs, concession freezers, and more. Cobb County SPLOST rebuilt both parks and added LED lights on Harrison 6 & 7. Next: a cage for Sweat Field 2 and electronic signs at both parks.

Who we are
Sandy Plains Baseball Association
SPBA is the volunteer youth baseball association for Harrison Park and Sweat Mountain Park in Cobb County. We run recreational baseball ages 4–18, travel teams from 7U up, and Challenger baseball — the Party Animalz — at no cost.
We exist so kids in this community can play for their parks, learn the game, and stay in it. Apparel proceeds and hardship funds exist so registration cost is never the reason a player sits out.
Starting Spring 2026, Sandy Plains partners with Braves Country Baseball, which emphasizes playing at the local level and a lasting love for the game.
