Florida Spring Training Baseball — The Grapefruit League

Florida's Grapefruit League is the collective designation for the 15 Major League Baseball teams that conduct spring training in the state each February and March. With more than 130 years of documented presence, Florida has hosted over 1,100 individual team spring trainings — more than double the combined totals of the next two states, Arizona and California, according to Jonathan I. Leib's peer-reviewed study published in The Florida Geographer (Florida State University, 2001). The Florida Grapefruit League reports that since 2000 more than 38 million fans have attended Florida spring training games, with the 2026 season alone drawing nearly 1.4 million fans across 13 host communities. The Florida Sports Foundation identifies spring training as the origin point of Florida's professional sports industry, predating the establishment of every permanent MLB franchise in the state. Training grounds span 35 distinct Florida sites documented since 1889, stretching from Pensacola in the northwest to Port St. Lucie on the Atlantic coast, with the greatest concentration of current venues along the Gulf Coast corridor from Tampa south to Fort Myers.

The Philadelphia Phillies are documented as the first major-league club to train in Florida, spending two weeks in Jacksonville in 1889, according to Spring Training Online. By 1913, the Chicago Cubs had established a training camp in Tampa and the Cleveland Indians in Pensacola, marking the era when Florida spring training began its sustained presence. The Tampa Bay region emerged as the state's spring training core by the 1920s, according to Leib's study in The Florida Geographer. Leib, then an associate professor of geography at Florida State University, documented that St. Petersburg ranked first among all Florida spring training sites, having hosted 145 spring trainings — 13 percent of the state's total — through 2001.

The informal name 'Grapefruit League' carries two documented origin accounts. The Orange County Regional History Center records that aviator Ruth Law was hired in 1916 in Daytona Beach to drop a baseball from her plane to Brooklyn Dodgers manager Wilbert Robinson as a promotional stunt; she substituted a grapefruit, which exploded on Robinson, and the episode entered baseball vernacular. The Baseball Egg history site separately credits St. Petersburg mayor and sportswriter Al Lang, who was recognized for coaxing teams to the region and popularizing the name through his promotional efforts. Both accounts are rooted in the Tampa Bay–Daytona Beach corridor that defined Florida spring training in its formative decades.

The Detroit Tigers hold the longest-standing continuous relationship between a major-league team and a current Florida spring training host city. The Tigers have trained in Lakeland since 1934, and have played at Publix Field at Joker Marchant Stadium since 1966 — the 2026 season marks the team's 90th spring training in Lakeland and 61st at Joker Marchant Stadium, per the Florida Grapefruit League's official team page. Joker Marchant Stadium was built in 1966 on the former site of the Lodwick School of Aeronautics, a World War II flight training facility, according to LALtoday/6AM City, making it the second-oldest ballpark still in active use for spring training.

A landmark civil-rights moment in Florida spring training occurred on March 17, 1946, in Daytona Beach, when Jackie Robinson played for the Montreal Royals — the Brooklyn Dodgers' Triple-A affiliate — in the first racially integrated spring training game in modern professional baseball, per the Jackie Robinson Ballpark's official history. The ballpark at City Island, which had opened in 1914, was subsequently renamed Jackie Robinson Ballpark in recognition of that event. The game took place in a civic context shaped by Daytona Beach's Bethune-Cookman College and the presence of educator and civic leader Mary McLeod Bethune, whose influence helped make the integrated game possible in a Southern city operating under Jim Crow statutes.

Despite the 1946 milestone, integration of Florida spring training facilities was neither immediate nor complete. The Leib study in The Florida Geographer documents that full desegregation of both stadium seating and player housing at Florida spring training sites was not completed until 1962, under pressure from MLB, individual teams, and the state Chamber of Commerce. MLB.com's Jackie Robinson Training Complex history further documents this arc, including the role of Branch Rickey and the Dodgertown complex in Vero Beach — itself a deliberate attempt to create a self-contained facility where Black players could be housed and trained alongside white teammates during a period when local ordinances and customs prevented integrated hotel accommodations across much of Florida.

The 15 Grapefruit League teams are distributed across three regional corridors, with the Gulf Coast corridor holding the largest concentration of venues. Along that corridor — running from the greater Tampa Bay area south to Fort Myers — nine teams trained as of 2026: the New York Yankees at George M. Steinbrenner Field in Tampa, the Philadelphia Phillies at BayCare Ballpark in Clearwater, the Toronto Blue Jays at TD Ballpark in Dunedin, the Pittsburgh Pirates at LECOM Park in Bradenton, the Baltimore Orioles at Ed Smith Stadium in Sarasota, the Tampa Bay Rays at Charlotte Sports Park in Port Charlotte, the Atlanta Braves at CoolToday Park in North Port, and the Boston Red Sox and Minnesota Twins sharing the Fort Myers market at JetBlue Park and Hammond Stadium respectively, per ESPN's 2026 team location survey.

Central Florida's sole current Grapefruit League site is Publix Field at Joker Marchant Stadium in Lakeland, where the Detroit Tigers represent the only inland venue among the 15 current Florida franchises. The Atlantic and Southeast Florida corridor hosts four teams: the Houston Astros and Washington Nationals share CACTI Park of the Palm Beaches in West Palm Beach, the Miami Marlins and St. Louis Cardinals share Roger Dean Chevrolet Stadium in Jupiter, and the New York Mets train at Clover Park in Port St. Lucie. According to Ballpark Digest's Complete Guide to Spring Training 2026, the Gulf Coast and greater Tampa Bay zones contain the highest concentration of venues and generate the largest share of fan attendance statewide.

The Florida Sports Foundation commissioned a study by Tallahassee-based Downs & St. Germain Research that calculated the 2018 Grapefruit League season produced a $687.1 million economic impact for Florida. Of that total, $480.6 million was driven by non-resident visitor spending, with an estimated 7,152 jobs created generating $253.5 million in wages. Enterprise Florida corroborated the same study's findings. An earlier commissioned study covering the 2009 season, cited by ESPN, had calculated a $752 million economic impact from approximately 1.6 million fans attending 259 games at 15 locations, producing an estimated $47 million average per host community and supporting approximately 9,205 jobs.

The economic significance of spring training is particularly concentrated in mid-sized Florida cities — Lakeland, Sarasota, Dunedin, Bradenton, and Port Charlotte among them — where the approximately six-week season generates measurable hotel, restaurant, transportation, and retail activity that civic budgets and planning documents reference as a tourism anchor. Public financing of the underlying stadium infrastructure is an active civic policy question: the State of Florida contributed a $4.5 million grant toward a 2002 renovation of Joker Marchant Stadium in Lakeland, and Pinellas County voted 5–2 to authorize $312.5 million in bonds for a proposed Tampa Bay Rays regular-season facility in 2024, per ESPN.

The 2026 Grapefruit League season ran from February 20 through March 24, with the first official game — Yankees versus Orioles — played on February 20, per the Florida Grapefruit League's schedule announcement. The season also incorporated World Baseball Classic preparation games on March 3–4, with national teams representing Colombia, the Netherlands, Panama, Canada, and Puerto Rico playing exhibition games at Grapefruit League stadiums, per WUSF. The 2026 Florida Spring Training Guide, published by the Florida Sports Foundation, noted the return of Spring Breakout Games on March 20–21 — a prospect showcase format introduced the prior season — across all 15 Grapefruit League organizations. The season concluded with nearly 1.4 million fans in attendance and the cumulative since-2000 total surpassing 38 million, per the Florida Grapefruit League's post-season summary.

The Tampa Bay Rays' spring training situation became entangled in a broader stadium crisis during this period. In March 2025, the organization announced it would not proceed with a planned $1.3 billion stadium in St. Petersburg after Hurricane Milton in fall 2024 damaged Tropicana Field's roof, ripping off 18 of 24 fiberglass panels, per ESPN. The team played their 2025 regular-season home games at George M. Steinbrenner Field — the Yankees' spring training facility in Tampa — while stadium negotiations stalled. As of early 2026, the Florida cabinet and Governor Ron DeSantis approved a 22-acre state land transfer in Tampa, on a Hillsborough College campus site, for a potential new Rays ballpark, per ESPN. The ongoing situation underscores the overlap between spring training infrastructure, permanent-franchise facility policy, and Florida municipal finance.

Florida spring training intersects with several broader state-level systems documented in the research record. The civil-rights history embedded in Daytona Beach's Jackie Robinson Ballpark — and the documented arc from the March 17, 1946 integrated game through the full facility desegregation completed by 1962 — connects spring training to Florida's Jim Crow-era history and the legal and civic pressures that reshaped public accommodations across the state. The Florida Sports Foundation, in its official history, frames spring training as the institutional precursor to Florida's permanent MLB franchises: the Florida Marlins, established in 1993 (now the Miami Marlins), and the Tampa Bay Devil Rays, established in 1998 (now the Rays), both emerged from a state that had hosted professional baseball for a century before acquiring franchises of its own.

The stadium finance questions surrounding the Rays — including Pinellas County's 5–2 vote to authorize $312.5 million in bonds and the subsequent state land transfer in Hillsborough County — connect spring training's facility infrastructure debates to Florida's broader sports venue policy and municipal bond markets. The Leib study in The Florida Geographer further documents that since World War II Florida has accounted for 70 percent of all MLB spring training sites nationally, a geographic concentration reflecting the state's climate, land availability, and public investment in sports tourism infrastructure — all components of Florida's broader tourism and economic development policy landscape.
