Kostyuk: Sabalenka, Swiatek is much taller and stronger than me.
At the Wuhan Open 2025, Marta Kostyuk acknowledged that biological differences gave Aryna Sabalenka and Iga Swiatek an advantage. She hadn't won a single set in their seven encounters and chose to optimize what she had.
Speaking at the 2025 Wuhan Open, Marta Kostyuk touched on a heated debate in women's tennis: how much physical advantage can decide a match. The 23-year-old Ukrainian acknowledged the clear disparity when facing top champions: “They are much bigger, taller, and stronger than me.” This isn't just a feeling; it's reflected in her head-to-head record, where she hasn't won a single set against Aryna Sabalenka and Iga Swiatek.
The moment that sparked debate in Wuhan.
Kostyuk candidly described her feeling of helplessness in the face of Swiatek and Sabalenka's strength: "When I faced Iga, I wasn't ready to compete against her. She was too strong. With Aryna, it was always a tough battle." She added about natural biological differences: "Some people have higher testosterone levels, others have lower levels – that's perfectly natural." These simple yet sharp words immediately caused a stir in the tennis world.
The 2024/25 season saw Kostyuk's progress, but the Swiatek–Sabalenka wall remained unshaken. Every time she stepped onto the court, according to her, the feeling of being "small" compelled her to run more, hit more shots, just to win a point. It was a journey that demanded both physical and mental strength.
The numbers speak for themselves.
The reality of the confrontation revealed the gap that Kostyuk himself recognized:
| Competitor | Number of confrontations | Kostyuk's winning set | Note |
|---|---|---|---|
| Aryna Sabalenka | 4 | 0 | According to Kostyuk's statement. |
| Iga Swiatek | 3 | 0 | According to Kostyuk's statement. |
No numbers can fool an insider: facing two players who dominate the WTA Tour, Kostyuk is still searching for solutions to the physical challenges and power of his shots.
Tactical perspective: When physical disadvantages shape gameplay.
“I have to run more than them, hit more shots just to win a point” – Kostyuk’s assessment perfectly encapsulates her strategy when facing Swiatek or Sabalenka. Given her opponents are “taller and stronger,” her game plan revolves around increased movement, higher rally volume, and patiently waiting for open spaces. On the other side of the court, each heavy, deep, and early shot from her opponent narrows her time, requiring Kostyuk to win points with precision rather than pure power.
She couldn't change her body: "I can't just make myself gain 10kg or grow 5cm taller." Instead, the solution was to optimize everything she already had – from tempo and ball contact points to energy management in each game. This mindset suits players who know how to turn disadvantages into strengths: developing the ability to read the game, varying spin and direction to wear down their opponent's power over the course of the match.
Key statistics and the current picture
- Head-to-head record: 0 sets won in 4 matches against Sabalenka and 3 matches against Swiatek.
- 2024/25 period: achieved many impressive results, but still faced a "glass ceiling" against the two leading competitors.
- Key takeaway: the physical disparity is a reality, requiring adjustments in tactics and mindset.
Reactions and Aftershocks on the WTA Tour
Kostyuk's statement "stirred up the tennis world" not because of its extremism, but because of its authenticity. Her mention of biological differences – including natural testosterone levels – touches on a core question: how should women's sports be viewed when physical superiority creates a clear gap? Here, Kostyuk doesn't deny her opponent's talent; she acknowledges the disadvantage and chooses to confront it.
Impact: The Top 10 Journey and Reunions
Reaching the top 10 remains a daunting goal, especially with stars like Swiatek and Sabalenka forming a barrier in the later rounds. But Kostyuk's approach – "using 100% of what she has" – is the foundation of a long-term process. Each time she returns, if she can extend the games, increase her conversion rate of opportunities into decisive points, and maintain a consistent pace, the gap can narrow over time.
At the Wuhan tournament, the story wasn't just about winning zero sets. It was a statement of both strategy and mindset: acknowledging differences, optimizing oneself, and being ready for a war of attrition against opponents who were perfected in both strength and precision.
