Jacksonville became Major League Baseball's first spring training location when the city hosted the Washington Statesmen in 1888. Many of baseball's greatest African-American players wowed fans at Jacksonville's J. P. Small Park, including Hank Aaron, Satchel Paige, Roy Campanella, and James "Cool Papa" Bell.

A truly historic moment—Jackie Robinson breaking the color barrier—could have happened here in 1942, but he wasn't allowed to take the field with his teammates on the minor league Royals team. Rather than let him play, the stadium was padlocked.

Spring training has since moved south, but the baseball tradition here continued. Some of the sport's best players—Nolan Ryan, Tom Seaver, Randy Johnson, and Alex Rodriguez—did stints on Jacksonville's farm-league teams.
