What “Under 10.5” Means in Tennis Betting
“Under 10.5” refers to the total number of games played in a single set or entire match (depending on the bookmaker’s market).
- You are betting that the total number of games will be 10 or fewer — meaning 10 or less games are played.
- If the total games are 11 or more, your bet loses.
Example: Single Set Market
Let’s say the bet is Under 10.5 Games in Set 1 of a match between:
Carlos Alcaraz vs Casper Ruud
Winning Scenarios (Under 10.5 wins):
If the set ends quickly, like:
- 6–4 → Total = 10 games
- 6–3 → Total = 9 games
- 6–2 → Total = 8 games
Losing Scenarios (Under 10.5 loses):
If the set is very close:
- 7–5 → Total = 12 games
- 7–6 → Total = 13 games
So,you win only when the set is finished before reaching 11 total games.
Example: Full Match Market (Best of 3)
Suppose the bet is Under 10.5 Total Games for the entire match (this is rare but can appear in short-format markets or exhibition matches).
Let’s take Iga Świątek vs Sara Sorribes Tormo.
If Świątek dominates:
- 6–1, 6–3 → Total = 16 games (too high)
- 6–1, 6–0 → Total = 13 games (still above 10.5)
So, for a full match market, Under 10.5 would rarely win unless the format is short sets (like Fast4 or exhibition sets).
That’s why Under 10.5 is typically used for one set, not the full match.
Ideal Player Type for “Under 10.5” Bets
You should target dominant servers or baseline power players who often win sets quickly without long rallies or many breaks.
Example Players:
- Iga Świątek (WTA) – often wins sets 6–1, 6–2 due to her dominance.
- Novak Djokovic (ATP) vs weaker players – known to control sets easily.
- Jannik Sinner (ATP) – aggressive play and few long sets when in form.
When these players face opponents ranked much lower, Under 10.5 can be a valuable bet.
Practical Example
Match: Djokovic vs Jordan Thompson
Set 1 results:
- Djokovic wins 6–3 → Total = 9 games → Under 10.5 wins
- If set had gone 7–5 → Total = 12 games → Under 10.5 loses
So, if you expect Djokovic to dominate early, betting Under 10.5 in Set 1 is reasonable.
Betting Tips for “Under 10.5” in Tennis
- Check Player Mismatch:
Bet Under 10.5 when a top seed faces a weaker opponent (clear skill gap). - Clay vs Hard Courts:
Hard courts and indoor courts often favor shorter sets (Under 10.5 more likely).
Clay courts tend to have longer rallies → Avoid Under 10.5. - Look for Momentum Players:
Players who start aggressively (like Alcaraz, Świątek) often close sets quickly. - Avoid Tight Matchups:
If two players are closely ranked, expect longer sets (7–5 or 7–6 common). - Use Live Betting:
If a strong player breaks serve early (say 3–0 up), Under 10.5 becomes more likely — you can place live bets then.
