Zeynep Sonmez and Harriet Dart meet in the Eastbourne WTA round of 16 on grass on 22 June, with a quarter-final place on the line. The numbers strongly back the world No. 66, who has been one of the sharper grass-court performers this summer, while Dart arrives with just one win on the surface all season. That disparity is reflected in the odds and the recent form lines, setting up a match where the favourite's control appears well-grounded.

Sonmez's grass-court numbers dwarf Dart's

Sonmez has compiled a 7-2 record on grass this year, winning 73% of her service games and 41% of return games. Dart, by contrast, is 1-3 on the surface and has won just 22.5% of return games – a statistic that makes it difficult to sustain pressure. Those differentials explain why Sonmez has averaged 20.6 games per match in WTA grass-court events, while Dart's matches stretch to 26.7, often because of her struggle to close out sets.

Recent form gap widens between the two

Sonmez arrives with seven wins from her last ten outings, capturing 70% of service games and converting 47% of break points. Dart has lost seven of her last ten, with a first-set win rate of just 20%. That slow-start pattern leaves her vulnerable against a player who takes the opening set 60% of the time.

Bookmakers install Sonmez as heavy favourite

Sonmez is priced at 1.40 to win the match, with Dart available at 3.00. The first-set market is similarly one-sided at 1.44 versus 2.75. Those numbers underline the market's conviction that the gap in grass-court quality will tell quickly.

Return pressure and serve stability the difference

Sonmez's ability to win 41% of return games on grass puts her in a different category from Dart, whose 22.5% return-games-won percentage leaves almost no margin for error. Dart's serve can be effective, but her recent double-fault rate of 5.5 per match adds pressure. With Sonmez's workload manageable and no heavy fatigue, the match should unfold on her terms. Dart's best hope is to improve her first-set performance and test Sonmez's break-point saving, which sits at 56% on grass, but the numbers suggest an uphill task.

Harriet Dart

The numbers point overwhelmingly towards Sonmez. Her grass-court record this season and superior return game give her a clear advantage, while Dart's recent struggles and low first-set win rate add to the gulf. The market reflects that confidence, making the favourite the rightful call.
