The popularity of baseball caps grows with the development of the sport, with the batting of the base ball as the significant part of the team game, with a lot of confrontation. It has now become a world wide sport with significant influence and deemed by many as the combination of skill and wit, or brain and brawn team competition. It is so popular in the States and Japan that they are treated as "National Sport" of both countries. As this sport has become popular, so grows the baseball cap culture.
According to years of study by some experts in the United States in the arena of this game, baseball was originated from the cricket game of England, also known as Rounder. In 1893, an American called Doubleday organized the very first game, the prototype version of modern baseball game. During the competition, baseball players wore such cap with a long wide brim to shelter strong sunlight from the eyes to get better scores, the birth/advent of the earliest baseball cap.
