What Does “Under 22.5” Mean in Tennis Betting?
In tennis sports betting, “Under 22.5” refers to a total games bet. You’re betting that the total number of games played in the entire match will be less than 22.5.
- The “.5” means there can be no tie. The bet either wins or loses – no push (draw).
- If the match ends with 22 or fewer total games, your bet wins.
- If it ends with 23 or more games, your bet loses.
How to Count Total Games in a Match
Every game within each set counts. Here’s how:
- If a set ends 6–4 → that’s 10 games.
- If a set ends 7–5 → that’s 12 games.
- If a set ends 6–3, 6–2 → 9 + 8 = 17 games total.

Betting Tips for Under 22.5 in Tennis
- Look for Strong Favorites:
- If a top player is expected to win comfortably, the match may end in fewer games (e.g., 6–1, 6–2).
- Ideal when the opponent is weak or out of form.
- Avoid Even Matchups:
- Close matches often go to 3 sets (in best-of-3) or include tiebreaks → more games.
- Check Playing Style:
- Aggressive players with strong serve-and-volley may lead to quick games.
- Defensive baseline players tend to play long rallies and tight matches → more games.
- Surface Matters:
- Clay courts (e.g., French Open) → longer rallies, more games.
- Hard/Grass courts → faster games, better for Under 22.5.
- Look at Recent Form & Head-to-Head:
- If one player usually dominates the other, it’s a good sign for an “under” bet.
