A uniform is a type of sportswear worn by baseball players, and sometimes by non-playing personnel such as managers and coaches. Modern uniforms have the names and uniform numbers of the players on them; color differences and insignia are mainly used to distinguish players from the two teams.
The first uniforms, worn by the New York Knickerbockers Baseball Club, were composed of blue woolen trousers, white flannel shirts and straw hats. Since then, the uniform has changed dramatically, such as replacing straw hats with regular baseball caps and displaying the player's last name.
