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 team 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 college students.
Spring training typically lasts about six weeks, starting in mid February and running until just before the season opening day (and often right at the end of spring training, some teams will play spring training games on the same day other teams have opening day of the season), traditionally the first week of April. Pitchers and catchers report to spring training first because pitchers benefit from a longer training period. A few days later, the 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.

Movable seating is a feature of some facilities like stadiums, often known as convertible stadiums, or moduable stadiums. It allows for the movement of parts of the grandstand to allow for a change of the playing surface shape. This allows games that use various shaped playing surfaces such as an oval field, for cricket and/or Australian rules football; or a rectangular field, for football (soccer), rugby league, rugby union, American football, and/or Canadian football; or a diamond field, for baseball; to be played in the same stadium. This is particularly useful in Australia and the United States, where various professional sports with varying field configurations are popular spectator pastimes. The process of conversion from one form to another is time consuming - depending on the stadium it can take from 8 to 20 hours. Many stadiums were built in the United States in the 1960s and 1970s to host both baseball and American football.
Multi-purpose stadiums are a type of stadium designed to be easily used by multiple types of events. While any stadium could potentially host more than one type of sport or event, this concept usually refers to a specific design philosophy that stresses multi-functionality over specificity. It is used most commonly in Canada and the United States where the two most popular outdoor team sports, gridiron football and baseball, require radically different facilities. Football uses a rectangular field (Canadian football fields are larger than American ones) while baseball is played on a diamond. This requires a particular design to accommodate both, usually an oval. While building stadiums in this way means that sports teams and governments can share costs, it also imposes some challenges.
In North America, multi-purpose stadiums were built primarily during the 1960s and 1970s as shared home stadiums for Major League Baseball and National Football League or Canadian Football League teams. Some stadiums were renovated to allow multi-purpose configurations during the 1980s. This type of stadium is associated with an era of suburbanization, in which many sports teams followed their fans out of large cities into areas with cheaper, plentiful land. They were usually built near highways and had large parking lots but not often connected to public transit. As multi-purpose stadiums were rarely ideal for both sports usually housed in them, they had fallen out of favor by the 1990s. With the opening of the Truman Sports Complex in Kansas City, a model for purpose-built stadiums was laid down. Since Oriole Park at Camden Yards opened in 1992, most major league sports stadiums have been built specifically for one sport.
