Baseball stirrups, also called stirrup socks or simply stirrups, are socks that are part of a traditional baseball uniform, giving the uniform a distinctive look. Stirrup socks are usually one of a team's traditional colors, and are worn over long socks that are usually white in color. The stirrup sock lacks toe and heel sections, instead having a loop which fits within the arch of the foot. Over the years, the stirrup loop tended to get longer, exposing more of the white undersock, thus creating a look unique to baseball. Most contemporary players in Major League Baseball (MLB) do not wear stirrup socks, as uniform pants that extend all the way down to the ankle have become increasingly popular since the mid-1990s.

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. They are made out of polyester instead of cotton, because washing shrinks the cotton fabric.

When a batter takes their turn to hit, the catcher crouches behind home plate, in front of the (home) umpire, and receives the ball from the pitcher. In addition to this primary duty, the catcher is also called upon to master many other skills in order to field the position well. The role of the catcher is similar to that of the wicket-keeper in cricket, but in cricket, wicketkeepers are increasingly known for their batting abilities.
