Kostyuk vs Swiatek Prediction 31 May 2026


🔊 Will Marta Kostyuk’s flawless clay-court run continue? The Ukrainian remains the only player yet to lose during this segment of the season. In the Roland-Garros Round of 16, it’s Iga Swiatek who stands in her way. The Pole is a four-time Paris Grand Slam champion and has completely dominated Kostyuk in their head-to-head encounters so far. Can Marta, in her current form, finally notch her first win against Swiatek?
Head-to-Head
📊 Iga Swiatek have claimed victory in all four of her previous head-to-head clashes with Marta Kostyuk, including one by retirement. While this edge is worth noting, the current form of both players means their head-to-head record serves as just an additional factor rather than a decisive argument in favor of either competitor.

Iga Swiatek Player Overview
Iga Swiatek suffered three defeats during the clay-court swing, struggling at the WTA 500 event in Stuttgart and the Masters 1000 in Madrid. However, heading into Roland Garros, the Pole bounced back by reaching the semifinals at the Rome Masters. In Paris, she has yet to drop a set, cruising past Emerson Jones, Sara Bejlek, and Magda Linette-though her compatriot did give her a real test, taking eight games off the world No. 3. Poland’s top player continues to showcase her trademark dominance on clay: her first-serve accuracy is an impressive 68%, and she consistently wins a high percentage of points both on serve and return, converting more than half of her break-point chances.
Match Results: Iga Swiatek
Key factors
- Marta Kostyuk has played over 10.5 games in 15 consecutive matches.
- Kostyuk is unbeaten in her last 14 outings, showcasing impressive consistency.
- Matches featuring Kostyuk average 19.8 games.
Expected scenario
This match is unlikely to see either player take complete control from start to finish. During this clay-court season, Świątek have already played matches where they haven't looked as dominant as in their peak years. If Kostyuk can maintain a high first-serve percentage and keep unforced errors to a minimum during long rallies, she has every chance of staying close on the scoreboard throughout the contest.
⭐ Editorial Prediction
Marta Kostyuk’s impressive run of form and her string of strong performances suggest she’s capable of putting up a solid fight, even against the formidable challenge posed by Iga Swiatek. If Magda Linette-who isn’t exactly a top-tier name-managed to push the world number three and take eight games off her, then the in-form Ukrainian should have little trouble reaching a similar mark. Given these factors, backing Kostyuk +4.5 games looks like a smart play.
