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 early February and continues until just before Opening Day of the regular season, which falls in the last week of March or the first week of April. 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.
