Do You Have to Win by 2 in the 5th Set? Exploring Tennis Rules

Prior to this change, matches would often extend into an unnervingly endless final set, as players fought relentlessly to secure victory. However, with the introduction of the 10-point tiebreak, the dynamics of the game have shifted. In this new format, if the score reach es a deadlock at 9-9 or "nine all," the same formula applies, requiring a minimum lead of two points to claim the tiebreaker and ultimately emerge as the triumphant competitor. This rule brings an added layer of excitement and suspense to the game, while also ensuring a more reasonable and time-efficient conclusion for both players and spectators alike. In this article, we will delve deeper into this rule and explore the reasons behind it’s implementation, uncovering the impact it’s had on the sport as a whole.

How Many Points Is a Fifth Set in Tennis?

In the sport of tennis, there are specific rules governing how the fifth set is played. A fifth set is won when one of the players manages to win six games by a two-game margin. This ensures that the winner truly demonstrates their dominance and ability to perform consistently. However, things can get more interesting when both players are tied at 6-6, creating a tense situation where the outcome of the set is uncertain.

Traditionally, in such cases, a tiebreak is used to settle the fifth set. In most cases, this tiebreak is a 10-point tiebreak, which means that the first player to reach 10 points with a clear two-point lead will win the set. This system has been implemented over the years to prevent lengthy matches that can go on for hours, potentially affecting the players endurance and performance.

Setting a clear requirement of winning six games by a two-game margin is the foundation of this system, ensuring that the triumph is earned. The inclusion of a tiebreak when the set reaches a 6-6 tie adds an extra layer of drama, guaranteeing an exciting climax to matches while respecting the stamina of the players.

The History of Tiebreaks in Tennis and How the 10-Point Tiebreak Became the Standard for Fifth Sets.

In the early years of tennis, matches were played with no tiebreakers. This meant that the final set of a match could go on indefinitely until one player won by two games. Long and exhausting matches became common, sometimes lasting for hours and even days.

Realizing the need for a quicker and more decisive way to end matches, the tiebreak system was introduced. The first form of tiebreak, known as the “sudden-death” tiebreak, was played up to 9 points, and the player who reached 9 points first would win the set.

However, as tiebreaks gained popularity, it was noticed that a fifth set tiebreak had the potential to force a player to win by two points. To avoid lengthening matches even further, a new format was introduced: the 10-point tiebreak.

The 10-point tiebreak became the standard for the fifth set in many tournaments, including Grand Slam events. The player who reaches 10 points first, with a minimum 2-point advantage, wins the match. This rule has been applied in order to strike a balance between ensuring a fair outcome and avoiding excessively long matches.

Today, the 10-point tiebreak is widely accepted, and it’s shortened matches significantly while maintaining excitement and competitiveness in the final sets.


This rule, which is now also applied to all other Grand Slam tournaments, ensures that the final set doesn’t drag on indefinitely, providing a more definitive conclusion to the match. With a 10-point tiebreak being played when the score is tied at 9-9, players must now achieve a minimum lead of two points to secure victory. This rule not only adds excitement and suspense to the fifth set, but also ensures that matches don’t become excessively long and physically demanding.
