Triple-A (officially Class AAA[1]) has been the highest level of play in Minor League Baseball in the United States since 1946.

Some additional events, such as the All-Star Fan Fest and Triple-A Home Run Derby, were held each year during this break in the regular season.

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.
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.
