Spring Training collection

Founding of the Grapefruit League The Philadelphia Phillies were the first of the major-league teams to train in Florida, when they spent two weeks in Jacksonville, Florida in 1889. Spring training in Florida began in earnest in 1913, when the Chicago Cubs trained in Tampa and the Cleveland Indians in Pensacola. One year later, two other teams moved to Florida for spring training, the real start of the Grapefruit League. Except for a couple of years during World War II, when travel restrictions prevented teams from training south of the Potomac and Ohio Rivers, Florida hosted more than half of the spring training teams through 2009. Since 2010, major league teams have been equally divided between Arizona and Florida during spring training, with 15 teams in Florida and 15 teams in Arizona. All but six of the major league teams have gone to spring training in Florida at one time or another (Anaheim Angels, Milwaukee Brewers, Seattle Mariners, San Diego Padres, Colorado Rockies and Arizona Diamondbacks). Many of the most famous players in baseball history (Ruth, Gehrig, Musial, Cobb, Mays, DiMaggio, Berra, Mantle, and many more) have called Florida home for four to six weeks every spring.--wikipedia

Founding of the Cactus League According to the autobiography of former Cleveland Indians owner Bill Veeck, the avoidance of racism was one reason the Cactus League was established. In the mid 1940's, Veeck was the owner of the minor league Milwaukee Brewers and the team trained in Ocala, Florida. Veeck inadvertently sat in the Black section of the segregated stands and engaged in conversation with a couple of fans. According to Veeck's book, the local law enforcement told Veeck he could not sit in that section, and then called the Ocala mayor when Veeck argued back. The mayor finally backed down when Veeck threatened to take his team elsewhere for spring training and promised to let the country know why.

Veeck sold the Brewers in 1945 and temporarily retired to a ranch in Tucson, Arizona, but purchased the Cleveland Indians in 1946. Intending to introduce African-American players, Veeck decided to buck tradition and train the Indians in Tucson and convinced the New York Giants to give Phoenix a try. Thus the Cactus League was born. In 1947, Veeck signed Larry Doby to the Indians. Doby was the second African-American to play MLB in the 20th century, and the first in the American League. Arizona had eight teams in the Cactus League in 1989, with the other eighteen in Florida. By 2018, the split was even, with 15 teams training in each location.--wikipedia
