What is Advantage in Tennis
Advantage in tennis is the score awarded to the player who wins the first point after deuce (40–40). If that player wins the following point, they win the game. If they lose the next point, the score returns to deuce.
Detailed Explanation
Advantage in tennis comes into play only after both players reach deuce. Since a tennis game must be won by a two-point margin, winning the point after deuce does not immediately end the game. Instead, it gives one player the advantage.
There are two types of advantage:
- Ad In – the server wins the point after deuce.
- Ad Out – the receiver wins the point after deuce.
If the player holding advantage wins the next rally, they win the game. If their opponent wins the next point instead, the score returns to deuce, and the battle continues until one player wins two consecutive points.
How It Looks in a Match
Example 1 – Match Situation
The score is 40–40. The server wins a long rally, making the score Advantage In. On the next point, the server hits a forehand winner to secure the game.
Example 2 – Professional Tennis
In closely contested ATP and WTA matches, games often feature multiple deuce and advantage exchanges before either player finally wins two consecutive points. These extended games can become key turning points in a set.

Why Advantage in Tennis Matters
- Ensures a player wins a game by a two-point margin.
- Rewards players who perform well under pressure.
- Creates longer, more competitive service games.
- Often determines momentum in closely contested matches.
Games that reach multiple advantage points can influence a range of tennis betting markets, particularly those based on games, sets, and live match progress.
