A baseball uniform is a type of uniform worn by baseball players, coaches and managers.
Most baseball uniforms have the names and uniform numbers of players who wear them, usually on the backs of the uniforms to distinguish players from each other. Baseball shirts (jerseys), pants, shoes, socks, caps, and gloves are parts of baseball uniforms. Most uniforms have different logos and colors to aid players, officials, and spectators in distinguishing the two teams from each other and the officials.
Baseball uniforms were first worn by the New York Knickerbockers Baseball Club in 1849.[1] Today, sales of replica uniforms and derivative branded products generate large amounts of income for Major League teams through merchandising.
