The Osceola County Stadium and Complex underwent a significant renovation in 2003 at a price of US$18.4 million[3] The renovation increased seating capacity, upgraded the press box, improved the clubhouses, and added "Autograph Alley" which is a popular feature of spring training events.
In May 2019, the Florida Fire Frogs accepted a half-million-dollar buyout from the county to leave at the end of the 2019 season. The stadium will be redeveloped to be part of a larger 20-acre (8.1 ha) training complex at Osceola Heritage Park for Orlando City SC of Major League Soccer to house its senior MLS team, USL League One reserve team and Development Academy. As well as the stadium, the training ground will also include four practice fields - three natural grass and one artificial turf - a fitness, training and recovery center; a players’ lounge; meal room and a film room as well as 30,000 square feet (2,800 m2) of office space for working staff and facilities to support media operations.[4][5]
The Osceola County Complex was also home of the Jim Evans Academy of Professional Umpiring where many hopeful future major league umpires went to learn the trade.[citation needed] Additionally, it hosts numerous amateur baseball events throughout the remainder of the year in conjunction with the United States Specialty Sports Association, Triple Crown Sports, World Baseball Federation, and Promotion Sports.[citation needed]
In the mid-1990s Osceola County Stadium was planned to be the home of the yet-to-be named Central Florida team, a charter franchise of the United League (UL) which was a planned third league of Major League Baseball (MLB).[8]
