In tennis, a "set" refers to a division of the match where players compete to win a specific number of games, typically six, while leading by at least two games. Wins within a set contribute to the overall match score, and matches are generally played in best-of-three or best-of-five sets. The concept of a set adds structure to the game, allowing players to focus on winning each segment strategically. Additionally, mental resilience and adaptability play vital roles in a player’s ability to secure a set.
