Baseball, 1992, a new sport that officially entered the Olympic Games, the oldest professional sport in the North American continent, the "tradition" of the United States and the "national ball" of Cuba, will perform their last swan song in this Olympic Games.

In June 2005, the International Olympic Committee decided at the plenary session held in Singapore that the baseball and softball events would be cancelled in the 20 12 London Olympic Games. In July 2007, the International Olympic Committee decided again that these two events would not be established in the 20 16 Olympic Games.

The International Olympic Committee made this decision because Major League Baseball, which represents the highest level of baseball in the world, is unwilling to send first-team players to participate in the competition, and at the same time is unwilling to accept strict drug testing. Bob Watson, head coach of the American baseball team, admitted that the United States would definitely not send first-class professional players to participate because the Olympic Games and the American professional baseball season overlap.

At the same time, because baseball is only popular in some countries and regions in America and Asia, the International Olympic Committee with a strong European background is not very keen on this project. Therefore, under the trend of "slimming down the Olympic Games", the baseball project that "humiliated the International Olympic Committee" was disqualified from participating in the Olympic Games.
