The Barons played at Rickwood Field, the stadium they shared with the Negro League team the Birmingham Black Barons. The Barons still play today, now as an affiliate of the Chicago White Sox, and continue to play one regular season game every season at Rickwood Field.","images":["https://cdn.shopify.com/s/files/1/1487/1618/files/21799545_02.jpg?v=1722976760","https://cdn.shopify.com/s/files/1/1487/1618/files/21799545_03.jpg?v=1722976759","https://cdn.shopify.com/s/files/1/1487/1618/files/21799553_03.jpg?v=1722976759","https://cdn.shopify.com/s/files/1/1487/1618/files/21799545_04.jpg?v=1722976759"],"price":28,"currency":"USD","in_stock":true,"inventory_qty":59994,"dynamic_pricing":false,"listed_at":"2026-06-18T20:30:38.001Z"},"share_url":"https://firestarter.network/l/lst_4RHLhXqX","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
