Dead rubber is a term used in sporting parlance to describe a match in a series where the series result has already been decided by earlier matches. The dead rubber match therefore has no effect on the winner and loser of the series, other than the total number of matches won and lost.
For example, in a Davis Cup series, each pair of competing countries play five matches (rubbers) where the winner is decided on a best-of-five basis. Once one team has reached three victories, the remaining match or matches are said to be dead rubbers. International Tennis Federation's last revision of the competition policies on dead rubbers is from 2011.
Since the result of a dead rubber has no impact in determining the winner of a series, dead rubbers are typically played in a less intense atmosphere, often allowing the team that has lost the series to obtain a match win. Sometimes, second-string players who have not played many matches in top-level competition are given the opportunity to play a dead rubber in order to gain experience. This practice makes completing a clean sweep of a series less likely.
