By Juan Pablo Aravena in Tennis
Published:
- Back the Kostyuk moneyline (-122) after her dominant upset of world No. 3 Iga Świątek
- Over 22.5 games (-120) could be an interesting option given Svitolina’s two three-set matches this tournament
- Kostyuk’s 67% R4 break-point conversion signals peak clay form ahead of a tough matchup vs Svitolina
The French Open Women’s Singles quarterfinals deliver an all-Ukrainian showdown on Monday, June 2, at 5:10 AM EST, as seventh-seeded Elina Svitolina takes on 15th-seeded Marta Kostyuk on Court Philippe Chatrier.
Kostyuk enters as the slight betting favorite at -122 on Kalshi after her stunning fourth-round demolition of three-time Roland Garros champion Iga Świątek. Svitolina, meanwhile, is listed at +122 after needing three sets to overcome No. 11 Belinda Bencic. This is their first meeting on clay and serves as a rubber match with the head-to-head series locked at one win apiece.
Svitolina vs Kostyuk Picks & Predictions
I am backing Kostyuk based on her surging tournament form and the raw statistical evidence from her fourth-round demolition of Świątek. In that match, Kostyuk converted 6-of-9 break points (67%), fired 5 aces, and won 79 total points to Świątek’s 57 in a commanding 7-5, 6-1 victory over the three-time Roland Garros champion.
It’s also worth noting that Kostyuk posted a 65% first-serve win rate and held a 52% second-serve win percentage against one of the tour’s best returners, a performance that signals complete confidence in her game. That level of production against a top-3 player on clay is not a fluke, and it represents a player peaking at exactly the right moment. She’s undoubtedly playing one of the best tournaments of her career.
Pick #1: Marta Kostyuk Moneyline (-122)
While Svitolina holds the higher ranking (No. 7 with 4,315 points vs. Kostyuk’s No. 15 with 2,387) and sits at No. 3 in the WTA Singles Race with 3,460 points, the tournament data tells a different story about current form.
Svitolina has been pushed to three sets twice in Paris. She had to survive a first-round scare against Anna Bondár (3-6, 6-1, 7-6) and needed to come from behind against No. 11 Belinda Bencic (4-6, 6-4, 6-0) in the fourth round. That resilience is admirable, but it also reveals vulnerability. Svitolina was broken early and forced to fight through adversity in both matches. Her first-serve win percentage has fluctuated between 61% and 71% across rounds, showing inconsistency, while her second-serve win percentage averaged just 57% for the tournament (58%, 55%, 53%, 62%).
Kostyuk, meanwhile, has been increasingly dominant. After dropping her first set of the tournament in a tiebreak against Katie Volynets in Round 2, she rattled off straight-set wins over Viktorija Golubic (6-4, 6-3) and Świątek (7-5, 6-1), with each set being more convincing than the last. Her second-serve win percentage has been stellar this tournament, averaging 62% across four matches (74%, 56%, 64%, 52%) compared to Svitolina’s 57%. On clay, where rallies extend and second-serve vulnerability gets punished, that five-percentage-point gap is significant. Kostyuk has also won 335 total points across four matches to her opponents’ 268, a dominant 56% point share. I am laying the -122 with Kostyuk’s form trajectory pointing sharply upward.
Pick #2: Over 22.5 Games (-120)
When these two compatriots share the court, the margins are razor-thin. Their history suggests they match up exceptionally well against one another, making a quick straight-sets blowout highly improbable. Their most recent meeting at the WTA level was in the WTA 1000 of Toronto in 2024. It was a grueling 24-game, three-set rollercoaster that saw Kostyuk win. That marathon proves that neither player yields early breaks without immediate return fire.
The tournament data further bolsters this angle. Svitolina has played 56 games across four matches, averaging 14 per match, and has been taken to three sets twice. She needed 29 games to get past Bondár in Round 1 and 26 games to outlast Bencic in Round 4. Her path clearly indicates she is susceptible to extended matches against quality opponents, and Kostyuk certainly qualifies. Kostyuk herself went to three sets against Volynets in Round 2 (31 games total in that match alone), proving she is not immune to prolonged battles either.
Even their abbreviated single-set format match in late 2025 was a fiercely contested 12-game sprint before Svitolina secured the decisive break. The situational trend is clear: they consistently push each other to the limit. Given the slow clay surface of Court Philippe Chatrier, break-point conversion becomes even more challenging—Svitolina converted just 22-of-42 break points this tournament (52%) while Kostyuk converted 22-of-50 (44%) prior to her R4 surge. Those conversion struggles against lesser opponents suggest multiple break-back sequences in this quarterfinal, forcing longer sets and pushing the total well past 22.5 games.

Svitolina vs Kostyuk: Head-to-Head History
The head-to-head record between the two Ukrainian stars gives Svitolina a slight 2-1 lead, although it’s perfectly deadlocked at one win apiece if we consider only the WTA-based events, making this upcoming quarterfinal clash a true rubber match.
Svitolina drew first blood in their rivalry during the Round of 32 at the 2018 Australian Open, winning in straight sets, but Kostyuk evened things up in the 2024 WTA Toronto event, navigating a volatile three-set battle to secure the victory. Svitolina answered back more than a year later at the World Tennis League in December 2025, edging out Kostyuk 7-5 in a single-set exhibition format.
The major disparity between these two matchups lies in the surface and format. Surfaces like Melbourne and Toronto provided a fast hard-court environment that favored Kostyuk’s aggressive baseline driving, while the upcoming Roland Garros match shifts the dynamic entirely to clay, as it’s a surface where Kostyuk has now proven herself at the highest level by ousting Świątek.
With their history split evenly and Kostyuk’s confidence at an all-time high after her stunning fourth-round upset, she holds a decisive edge in momentum entering this quarterfinal on the tour’s most demanding surface.
