Since 1993, the city of Fort Myers in Lee County, Florida, United States has been the Spring training home of the Boston Red Sox when the club moved from Winter Haven. Boston trains at the JetBlue Park at Fenway South since the ballpark opened in 2012, and the minor-league facility, featuring five full fields, is also within the Fenway South complex.
The Minnesota Twins play their spring training at Hammond Stadium, which is also located in Fort Myers. Each spring the two teams will play five of their preseason games against each other in a series known as the Mayor's Cup.
The Red Sox's spring training lease with Fort Myers ran through 2019, however, the Red Sox began toying with exercising an early out in their contract that allowed them to leave following the 2009 spring season. Chief operating officer Mike Dee met with Sarasota officials on April 25, 2008 to discuss the possibility of the Red Sox moving to Sarasota's Ed Smith Stadium once its current spring inhabitants, the Baltimore Orioles, move to their new spring home in Sarasota.
On October 28, 2008, the Lee County commission voted 13-11 to approve an agreement with the Boston Red Sox to build a new spring-training facility for the team in south Lee County. Dee was present in the chambers for the vote, and took the agreement back to Boston to meet with team owner John W. Henry and other team officials. On November 15, 2008, the Red Sox signed an agreement with Lee County that will keep their spring training home in the Fort Myers area for 20 more years.
