In tennis, the term "set" refers to a segment of a match where players compete to win a predetermined number of games, usually six. To win a set, a player must win at least six games and have a two-game lead over their opponent. Sets can impact the overall score of a match, which is typically played in best-of-three or best-of-five sets. Winning a set showcases a player's ability to maintain focus, adapt to their opponent's style, and perform under pressure, making it a crucial aspect of competitive tennis.
