the philadelphia phillies were the first of the current 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 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. 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 4–6 weeks every spring.
