“2nd Set – Total Aces” in Tennis Sports Betting Explained
The “2nd Set – Total Aces” betting market in tennis focuses only on the number of aces served during the second setof a match.
It doesn’t matter who wins the set or the match — only how many aces are served in that specific set.
How It Works
Bookmakers set a line (for example, 5.5 aces) for the second set, and bettors choose whether the total aces in that set will be:
- Over 5.5 → 6 or more aces in the 2nd set
- Under 5.5 → 5 or fewer aces in the 2nd set
You can also find exact total aces or player-specific ace totals (e.g., “Djokovic Over 3.5 aces in 2nd set”).
Example with Players
Example 1:
Match: Novak Djokovic vs. Taylor Fritz
Bet: 2nd Set – Total Aces Over 5.5
- In the 2nd set, Djokovic serves 2 aces.
- Fritz serves 4 aces.
- Total = 6 aces
Your bet wins, because 6 > 5.5.
Example 2:
Match: Iga Świątek vs. Aryna Sabalenka
Bet: 2nd Set – Total Aces Under 4.5
- Świątek serves 1 ace.
- Sabalenka serves 2 aces.
- Total = 3 aces
Bet wins, because total aces are below 4.5.
Example 3:
Match: Daniil Medvedev vs. Jannik Sinner
Bet: Medvedev – 2nd Set Total Aces Over 3.5
If Medvedev hits 4 or more aces in that set, your bet wins — regardless of how many Sinner serves.
Factors to Consider Before Betting
- Player Serve Strength
- Big servers like Isner, Fritz, Hurkacz, or Sabalenka tend to hit more aces.
- Consistent baseliners like Djokovic or Świątek rely more on rally play.
- Court Surface
- Grass and indoor hard courts favor aces due to fast conditions.
- Clay courts produce fewer aces.
- Match Momentum
- A player losing the first set might serve harder in the 2nd set to fight back.
- Conversely, if one player is clearly dominant, rallies might be shorter, reducing ace chances.
- Weather Conditions
- Windy or humid conditions can lower ace counts in outdoor matches.
- Tiebreak Probability
- A tiebreak in the 2nd set often increases ace totals because more points are played.
Betting Tips
1: Check players’ ace averages per set or per match (available on ATP/WTA stats sites).
2: Over bets are better in matches between two strong servers.
3: Under bets make sense in long baseline battles or on clay courts.
4: Watch the 1st set performance — if both players are serving big and holding easily, Over for 2nd set is appealing.
5: In women’s tennis, ace totals are usually lower, so Under 5.5 or 4.5 often has value.
Example Betting Strategy
- Men’s Hard Court Example:
Match: Alexander Zverev vs. Matteo Berrettini
Bet: 2nd Set Total Aces Over 7.5
Reason: Both are powerful servers, likely to hold serve and reach a tiebreak in the 2nd set. - Women’s Clay Court Example:
Match: Swiatek vs. Gauff
Bet: 2nd Set Total Aces Under 3.5
Reason: Both rely on rallies, few free points on serve.
