Quick Take

Pre-match view

Context last updated 2 Oct 2026, 04:12 · Europe/Bucharest

Mertens is 19th and won the pair's only meeting 6-3 6-1 in 2024, but Volynets has won 10 of 14 hard-court matches in this window to Mertens' 6-5 and already has a win in Beijing.

Mertens is the likelier winner; at 1.8 she offers nothing extra. Of the quoted prices reviewed, three sets at 2.3 is the one worth considering.

Context

Mertens lost the Singapore title she had won, beaten in straight sets with only four games on the board, and she has not won a match since the first week of September. That makes her recent form less settled than her ranking position implies going into a WTA 1000 second round against an opponent who already has a win this week. The Singapore match was played on indoor hard courts, so it does not transfer directly to the outdoor conditions in Beijing; the relevant signal is the margin, not the surface.
- Mertens was the defending champion at the Singapore Open.
- She lost 6-2 6-2 to Maja Chwalinska in the quarter-finals .
ConfirmedSources checked 2 Oct 2026, 04:10 · Europe/BucharestChina Open second-round previewwww.thestatszone.com · 1 Oct 2026
The single head-to-head result is more than two years old and predates Volynets' current hard-court run.
Mertens dropped only four games in that 2024 meeting, which is the clearest direct reference point between the two. Volynets has since won 10 of 14 hard-court matches and 58.2% of her games in the current window, so the old scoreline stands as a counterweight rather than a guide to the same margin.
- Elise Mertens beat Katie Volynets 6-3 6-1 on 7 August 2024, the only recorded meeting between them.
Volynets has been a fast starter and a strong front-runner across her recent hard-court sample.
That record is why an early Volynets lead against a higher-ranked opponent would fit the pattern. The same 14-match sample also contains one straight-sets defeat and three lost first sets, so it describes a tendency in a small sample rather than a guarantee against Mertens.
- Volynets won the first set in 11 of 14 hard-court matches and the second set in 11 of 14, from 27 July to 1 October 2026.
- She averaged 5.9 games won and 3.8 games lost in first sets across that sample.
Mertens' recent hard-court matches have tended to run long rather than finish quickly.
Her 11-match sample averages 2.55 sets and 22.5 games, and she has split those six deciders 3-3. Distance has therefore been a feature of her matches without being a reliable advantage for her, which is the counterweight to assuming a long contest simply favours the higher-ranked player.
- Mertens' 11 hard-court matches from 5 August to 25 September 2026 included six three-set results: three wins and three losses.
- Her hard-court matches in that window average 2.55 sets and 22.5 games.
