Spring training is the preseason in Major League Baseball (MLB), a series of practices and exhibition games preceding the start of the regular season. Spring training allows new players to try out for roster and position spots, and gives established players practice time prior to competitive play. Spring training has always attracted fan attention, drawing crowds who travel to the warm climates of Arizona and Florida to enjoy the weather and watch their favorite teams play.
In modern training, teams that train in Florida will play other Florida-training teams in their exhibition games, regardless of regular-season league affiliations. Likewise, Arizona-training teams will play other Arizona teams. These have been nicknamed the Grapefruit League and Cactus League, respectively, after plants typical of the respective states.
Spring training typically starts in mid-February and continues until just before Opening Day of the regular season, which falls in the last week of March. In some years, teams not scheduled to play on Opening Day will play spring training games that day. Pitchers and catchers report to spring training first because pitchers benefit from a longer training period. A few days later, position players arrive and team practice begins. Exhibition games usually begin in late February.
The New York Mutuals became perhaps the first baseball team to hold a spring training outside of their home when, in 1869, Boss Tweed sent the Mutuals south to New Orleans to prepare for the season. In the 1870s, several clubs began following the example set by the Mutuals by training in warmer climates. New Orleans was a popular location for spring training in the 19th century but teams also trained in Washington, D.C., Savannah, Georgia and Cape May, New Jersey among other locations. In 1888, the Washington Nationals became the first club to hold spring training in Florida. The practice was not universally adopted, however. Critics including Cap Anson argued that players would be more prone to sore muscles and colds after returning to their colder home climates.
