Jim Folk, Cleveland Indians
Vice president of ballpark operations
This month, Folk celebrates 25 years with the Indians, most of which have been spent running Progressive Field, which opened as Jacobs Field in 1994. Previously, he opened and operated the Florida Suncoast Dome, now Tropicana Field. Folk got his start in sports with the Chicago White Sox as a part-time security guard in the summer of 1979, and he worked the infamous Disco Demolition promotion at old Comiskey Park.
