Former legendary Boston Red Sox general manager Theo Epstein maintains a formal ownership stake and advisory role with Fenway Sports Group, the parent company that owns the Boston Red Sox, Liverpool F.C., and several other major sports properties. After etching his name into baseball history by building championship rosters that ended historic World Series droughts in both Boston and Chicago, Epstein returned to the Fenway Sports Group corporate umbrella as a senior advisor and part owner. In this high-level executive capacity, he provides strategic oversight, operational guidance, and long-term vision across the global sports conglomerate, continuing his influential legacy in professional sports management.
