Dunedin Blue Jays

The Dunedin Blue Jays share their name, their colors, and their spring training home with the Toronto Blue Jays — making this Gulf Coast outpost one of the most tightly integrated Single-A operations in baseball. Nearly five decades of continuous affiliation have produced a pipeline of future stars and a cherished community tradition.

The Foundation Years

Building a pipeline in paradise

The Toronto Blue Jays established their spring training operations in Dunedin during their inaugural 1977 season, and by 1978 they had placed a Florida State League affiliate in the same city. The original Dunedin Blue Jays operated through the mid-1980s before a brief hiatus and franchise restructuring.

The modern incarnation of the Dunedin Blue Jays began in 1987, continuing the unbroken chain between the parent club and the Gulf Coast community. Playing at the stadium that would eventually become TD Ballpark (originally built on the site of Grant Field from 1930), the Dunedin Blue Jays quickly became a staple of the Florida State League.

Throughout the 1990s, the team served as a crucial development stop for Toronto's farm system. The Blue Jays organization, which had won back-to-back World Series titles in 1992 and 1993, relied on Dunedin as a key proving ground for young talent. The intimate setting and year-round Florida weather made it an ideal environment for prospect development.

New Millennium, Same Mission

Prospect development at the highest level

Under Rogers Communications' ownership of the parent club beginning in 2000, the Dunedin Blue Jays entered a new era of investment and modernization. The ballpark underwent multiple naming changes — Knology Park (2004-2008), Florida Auto Exchange Stadium (2010-2018) — reflecting an evolving business landscape, but the on-field mission remained constant: develop the next generation of Toronto Blue Jays.

The franchise reached a milestone in 2017 when the Dunedin Blue Jays won the Florida State League championship, defeating the Tampa Yankees two games to one (the championship series with the Palm Beach Cardinals was canceled due to Hurricane Irma, resulting in co-champions). It was the first FSL title in franchise history and a crowning achievement for a program known more for player development than postseason hardware.

Perhaps the most exciting period came in the late 2010s, when the Blue Jays' farm system produced a remarkable crop of talent. Vladimir Guerrero Jr. and Bo Bichette both passed through Dunedin, giving local fans a glimpse of the electric young stars who would transform Toronto's major league roster.

Key Facts

  • Rogers Communications took over parent club ownership in 2000
  • Won 2017 FSL Championship (co-champions with Palm Beach Cardinals)
  • Vladimir Guerrero Jr. and Bo Bichette developed in Dunedin

2021–Present

TD Ballpark & Single-A

A renovated home and continued excellence

The 2020 season was canceled due to the COVID-19 pandemic, but it coincided with a massive renovation of the ballpark, which reopened as TD Ballpark. The $100 million-plus project, backed by a 25-year lease agreement between the Blue Jays, the city of Dunedin, Pinellas County, and the state of Florida, transformed the facility into one of the finest spring training and minor league complexes in the country.

The 2021 MiLB reorganization reclassified the Dunedin Blue Jays from High-A to Single-A, placing them in the revamped Florida State League. Despite the level change, the franchise's role as the first full-season stop in Toronto's development pipeline remained crucial. The state-of-the-art Player Development Complex adjacent to TD Ballpark gives Dunedin prospects access to cutting-edge technology and major-league-caliber facilities.

Under first-year manager Ryan Casteel for 2026, the Dunedin Blue Jays continue nearly five decades of continuous affiliation with Toronto — one of the longest-running partnerships in minor league baseball. The combination of world-class facilities, Gulf Coast weather, and organizational commitment ensures that Dunedin will remain a cornerstone of the Blue Jays' development system for years to come.

  • TD Ballpark renovation completed as part of $100M+ project
  • 25-year lease agreement secures franchise's future in Dunedin
