Captain (baseball)

In the early days of baseball, a captain was a player who was responsible for many of the functions now assumed by managers and coaches, such as preparing lineups, making decisions about strategy, and encouraging teamwork.

[1] In amateur or youth baseball, a manager or coach may appoint a team captain to assist in communicating with the players and to encourage teamwork and improvement.

[3] Only a few major league teams have had captains in recent years, two examples being Adrián Beltré of the Texas Rangers and David Wright of the New York Mets, both of whom served in the role from 2013 through 2018.

Brandon Belt of the San Francisco Giants wore an unofficial "C" patch (made from electrical tape) in a game on September 10, 2021, as a joke.

If the umpire made a decision that could "be plainly shown by the code of rules to have been illegal", the "captain alone shall be allowed to make the appeal for reversal."
