Quick Take

Pre-match view

Context last updated 13 Sep 2026, 22:42 · Europe/Bucharest

Hruncakova's superior recent form and dominant first serve make her the value pick against an out-of-form Andreeva.

Back Hruncakova to win the match and the first set, and consider the over on total aces. Avoid Andreeva as a favorite at 1.73.

Context

Hruncakova, 225th, is a right-hander with a powerful serve, averaging 8.7 aces per match in her last 15. Andreeva, 215th, has a weaker recent record and has lost both hard-court matches in that span.
Hruncakova's 60% win rate and 75.6% first-serve points won in her last 15 matches give her a clear edge over Andreeva, who has won only 40% of her matches and 59% of first-serve points. However, Hruncakova's hard-court record in that sample is just 2-3, so the surface may reduce her advantage.
- Hruncakova last 15 overall: 9-6 record, 75.6% first-serve points won, 8.7 aces per match.
- Andreeva last 15 overall: 6-9 record, 59% first-serve points won, 2.3 aces per match.
- Hruncakova last 15 on hard: 2-3 record, 66.9% first-serve points won.
- Andreeva last 15 on hard: 0-2 record, 62.5% first-serve points won.
Andreeva, 215th, has a career hard-court win percentage of 55% but has struggled recently on the surface.
In her last 15 matches, Andreeva is 0-2 on hard courts with a 46.4% games won rate and only 42.5% return points won. This suggests she may struggle against Hruncakova's serve, though the sample is very small.
- Andreeva last 15 on hard: 0-2 record, 46.4% games won, 42.5% return points won.
- Andreeva's last two hard-court matches were losses to Mariam Bolkvadze and Mai Hontama.
Hruncakova's aggressive serve comes with a high double-fault rate, averaging 4.3 per match in her last 15.
On hard courts, her double faults rise to 5.8 per match, which could hand Andreeva opportunities on second serves. Andreeva's return points won is 44.4% overall, so she may be able to capitalize on these errors.
- Hruncakova last 15 overall: 4.3 double faults per match.
- Hruncakova last 15 on hard: 5.8 double faults per match.
- Andreeva last 15 overall: 44.4% return points won.
This is a main-draw match at the WTA 125 Caldas da Rainha on hard courts, so both players are confirmed entrants with no additional preparation or fitness signals from the research.
- The event entry list includes Andreeva and Hruncakova among the direct main-draw entrants.
- The tournament overview identifies a WTA 125 hard-court event with a 32-player singles draw.
