Ukrainian tennis player Marta Kostyuk delivered the biggest win of her career at the 2026 French Open and one of the tournament’s most emotional moments.

The 23-year-old defeated fellow Ukrainian Elina Svitolina 6-3, 2-6, 6-2 in a historic Roland Garros quarterfinal to become the first Ukrainian woman in the Open Era to reach the French Open singles semifinals.

But the match carried weight far beyond tennis.

Hours before the two Ukrainians stepped onto Court Philippe Chatrier, Russia launched another wave of missile and drone attacks across Ukraine, killing at least 18 people. After sealing the victory, Kostyuk dedicated her performance to her country in an emotional on-court speech that left the Paris crowd applauding for nearly a minute.

“We had another difficult night in Ukraine, especially in Kyiv, where so many people died,” Kostyuk said through tears. “So I want to give this match to Ukraine.”

The moment instantly became one of the defining images of this year’s French Open.

Why Marta Kostyuk’s French Open Run Matters Beyond Tennis

Kostyuk’s breakthrough is historic on multiple levels.

She is now:

• The first Ukrainian woman in the Open Era to reach the French Open semifinals
• Only the third Ukrainian woman to reach a Grand Slam singles semifinal
• The first Ukrainian singles player — male or female — to make the Roland Garros semifinals since Andrei Medvedev in 1999

For Ukraine, the achievement arrives during one of the darkest periods in the nation’s modern history.

Since Russia’s invasion began in February 2022, Ukrainian athletes have competed under extraordinary emotional pressure. Many players, including Kostyuk and Svitolina, have spoken openly about balancing professional competition with fear for family members and friends back home.

That context transformed Tuesday’s quarterfinal into far more than a tennis match.

The First All-Ukrainian Grand Slam Quarterfinal Delivered High Drama

The match itself lived up to the occasion.

Kostyuk Started Fast

Kostyuk controlled the opening set with aggressive baseline play and sharp returning, breaking Svitolina’s serve early to take a 6-3 lead.

Her movement on clay — already one of her biggest strengths — consistently forced Svitolina into defensive positions.

Svitolina Responded Like a Veteran

The seventh seed rebounded in the second set, using her experience and consistency to slow the tempo of the match.

Svitolina won the set 6-2 and briefly appeared to have regained momentum. But Kostyuk reset quickly in the deciding third set, overpowering her compatriot with fearless shot-making and relentless depth from the baseline.

By the end, the younger Ukrainian had fully seized control.

An Emotional Finish on Court Philippe Chatrier

As the final point ended, emotion quickly overtook celebration.

Kostyuk became visibly emotional during her post-match interview, while former Wimbledon champion Marion Bartoli embraced her on court after the standing ovation from the Paris crowd.

The scene reflected the emotional burden Ukrainian athletes have carried throughout the war.

Marta Kostyuk Praised Elina Svitolina’s Influence on Ukrainian Tennis

Despite the significance of the victory, Kostyuk made sure to acknowledge Svitolina’s role in elevating Ukrainian tennis globally.

“I want to point out Elina’s incredible impact on tennis, Ukrainians, and me,” Kostyuk said. “She is incredible.”

That respect matters because Svitolina has long been the standard-bearer for Ukrainian women’s tennis. A former world No. 3 and Grand Slam semifinalist, she helped inspire a younger generation of players now breaking through on the biggest stages.

Kostyuk’s rise feels like the next chapter of that story.

The War in Ukraine Has Remained Central Throughout the Tournament

Kostyuk has repeatedly used her platform during the French Open to highlight the ongoing war.

Earlier in the tournament, she described her opening-round victory as one of the hardest matches of her career emotionally. She also shared images on social media showing damage near her family’s home in Kyiv following missile strikes.

Like several Ukrainian players, Kostyuk has also maintained the stance of not shaking hands with competitors from Russia and Belarus — a symbolic protest that has become one of the defining geopolitical tensions in professional tennis since 2022.

The timing of her quarterfinal victory made the moment even more powerful.

The match took place less than 24 hours after one of Russia’s largest attacks on Ukraine in recent months.

Kostyuk now advances to a blockbuster semifinal against Russian teenager Mirra Andreeva.

The matchup carries obvious political and emotional undertones given the ongoing war and the tensions that have followed Ukrainian and Russian players throughout international tennis events.

But from a sporting perspective, it may also be one of the most entertaining matches of the tournament.

Kostyuk Enters the Semifinal in Outstanding Form

The Ukrainian star arrives with a 17-match clay-court winning streak and appears increasingly comfortable in high-pressure moments.

Her movement, defensive range, and improved serve have made her one of the most dangerous players on clay this season.

The Backflip Celebration Could Return

Kostyuk also brought some humour to an otherwise emotional press conference.

When asked whether she would repeat the backflip celebration she performed after defeating Andreeva in Madrid earlier this season, she laughed and said:

“In Madrid I practised the day before the final.”

Then she added:
“I don’t need to practise here. I did it a month ago, but I promised I would only do it again when I win a final.”

That final may now be within reach.

Why Kostyuk’s Run Resonates Globally

Athletes often talk about “playing for something bigger than themselves.”

Few moments embody that phrase more clearly than Kostyuk’s run in Paris.

Her victories have unfolded alongside air raid sirens, missile strikes, and devastating news arriving daily from home. Yet she continues to compete with remarkable composure on one of the sport’s biggest stages.

For many fans, Kostyuk’s French Open campaign has become about more than rankings or trophies.

It has become a symbol of resilience.
