Onclin vs Sachko Prediction 25 August 2026
Gauthier Onclin and Vitaliy Sachko meet in the first round of the US Open qualifying tournament on hard courts. The match is shaping up based on the current form of the opponents, with one player demonstrating a clear advantage in consistency and results. The surface doesn't favor either player, but the overall dynamics of recent matches suggest a possible short-distance match.
Head-to-Head
The two players have met twice before, with Gauthier Onclin winning on both occasions. The head-to-head record gives the Belgian a slight edge, though it carries limited weight at this stage of qualifying.

Gauthier Onclin Player Overview
Gauthier Onclin arrives at this match having won seven of his last ten, a run that reflects solid current form.

Over those ten matches, the Belgian has won 60% of sets and held serve in an average of 73% of his service games.

Match Results: Gauthier Onclin
Vitaliy Sachko Player Overview
Vitaliy Sachko has won just four of his last ten matches, with five of those defeats coming without dropping - sorry, without taking a set. His first-serve percentage is a decent 66%, but his overall conversion of opportunities is modest: he has won only 39% of sets played and roughly half of all games. A particularly telling weakness is his slow starts - he has taken the opening set in just three of those ten matches. He hits 4.7 aces per match on average, though his double-fault count is also notable, and he tends to struggle more with holding serve in the second set.
Match Results: Vitaliy Sachko
Key factors
- Vitaliy Sachko has lost five of his last ten matches without taking a set.
- Gauthier Onclin has won 60% of sets in his last ten matches.
- The average number of games per match for both players is under 24.
- Onclin has won both of their previous head-to-head meetings.
- Sachko has a low first-set win rate - just 30%.
Expected scenario
Gauthier Onclin looks well placed to wrap this up in straight sets, with a solid hold record and a high percentage of sets won working in his favour. Sacko has a tendency to suffer bagel-set defeats and regularly struggles to take the opening set, which makes a third set unlikely. That fits neatly with the under, where the risk of the total going over the line appears limited.
⭐ Editor's Pick
Gauthier Onclin is in considerably better form right now - seven wins against his opponent's four - and his solidity on serve suggests he can wrap this up without the match dragging on in terms of sets or games. Vitaliy Sachko has too many straight-sets defeats on his record to make this a likely contest that goes deep. Given Onclin's advantages, the chosen line looks justified. Our pick is Total Games - Under 21.5.
