Spring Training

In Major League Baseball, spring training is 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 existing players practice time prior to competitive play. Spring training has always attracted fan attention, drawing crowds who travel to the warmer climates to enjoy the weather and watch their favorite teams play, and spring training usually coincides with spring break for many US college students.

Spring training typically starts in mid-February and continues until just before Opening Day of the regular season, traditionally 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. Team members normally wear their batting practice uniforms for the duration of spring training and only wear their normal jerseys beginning on Opening Day.

Spring training by major league teams in sites other than their regular season game sites first became popular in the 1890s and by 1910 was in wide use. Hot Springs, Arkansas has been called the original "birthplace" of Spring Training baseball. The location of Hot Springs and the concept of getting the players ready for the upcoming season was the brainchild of Chicago White Stockings (today's Chicago Cubs) team President Albert Spalding and Cap Anson. In 1886, the White Stockings traveled to Hot Springs to prepare for the upcoming season. Practicing at the Hot Springs Baseball Grounds, the White Stockings had a successful season and other teams took notice and began holding spring training in Hot Springs. The Cleveland Spiders, Detroit Tigers, Pittsburgh Pirates, Cincinnati Reds, Brooklyn Dodgers and Boston Red Sox followed the White Stockings to Hot Springs. Whittington Park/Ban Johnson Park (1894), Majestic Park (1909) and Fogel Field (1912) were all built in Hot Springs to host Major League teams.
