In my exploration of global passion for baseball, I found it's most popular in the United States, Cuba, Japan, and the Dominican Republic. The sport is deeply ingrained in the culture of these countries, with the US notably housing the globally recognized Major League Baseball. Cuba and the Dominican Republic, despite being smaller nations, are renowned for producing some of the world's best players. Japan's love for baseball is equally strong, with its Nippon Professional Baseball league attracting massive crowds. These four countries truly embody the spirit and passion for baseball.
