Triple-A (baseball)
Triple-A (officially Class AAA[1]) has been the highest level of play in Minor League Baseball in the United States since 1946. Currently, two leagues operate at the Triple-A level, the International League (IL) and the Pacific Coast League (PCL). There are 30 teams, one per each Major League Baseball (MLB) franchise, with 20 in the IL and 10 in the PCL. Triple-A teams are generally located in smaller cities as well as larger metropolitan areas without MLB teams, such as Austin, Jacksonville, Columbus, and Indianapolis. Four Triple-A teams play in the same metro areas as their parent clubs.[notes 1]

For other classifications, see AAA (disambiguation).All current Triple-A teams are located in the United States; before 2008, some Triple-A leagues also fielded teams in Canada,[2] and from 1967 to 2020 the Mexican League was classified as Triple-A. Other than the current two Triple-A leagues, only three other leagues have ever held the classification.
Leagues[edit]
Teams at this level are divided into two leagues: the International League and the Pacific Coast League. The International League fields teams primarily in the Eastern United States, while the Pacific Coast League fields teams mostly in the Western United States. Each of the 30 major league teams has an affiliation with one Triple-A team in the United States.
Pace-of-play initiatives[edit]
As a part of professional baseball's pace of play initiatives implemented in 2015, 20-second pitch clocks entered use at Triple-A stadiums in 2015.[23] In 2018, the time was shortened to 15 seconds when no runners are on base. Other significant changes implemented in 2018 included beginning extra innings with a runner on second base and limiting teams to six mound visits during a nine-inning game.[24] For the 2019 season, the number of mound visits was reduced to five, and pitchers were required to face a minimum of three consecutive batters unless the side is retired or the pitcher becomes injured and is unable to continue playing.[25]
