What Is “Set 2 – Game 4 – To Deuce” Betting?
This betting market asks:
Will Game 4 of Set 2 reach deuce (40–40) at least once?
- Yes – If the score in that game reaches 40–40
- No – If the game is decided before 40–40 (e.g. 40–0, 40–15, 40–30)
It does not matter who eventually wins the game. Only whether deuce occurs.

| 15–15 → 30–30 → 40–40 | Yes (Deuce) |
| 0–40 | No |
| 15–40 | No |
| 30–40 → Deuce | Yes |
