Ukrainian tennis star Marta Kostyuk is no stranger to turning heads, but this time it's not her powerful groundstrokes or fearless net play that has the tennis world talking. The world No. 10 sent social media into overdrive this week with a sizzling swimsuit photo that has fans hitting the like button faster than one of her aces.
The 22-year-old, who has enjoyed a breakout season on the WTA Tour, posted the snap on Instagram while she recovers from a wrist injury. In the photo, Kostyuk rocks a tiny white swimsuit that leaves little to the imagination, and the comments section quickly became a love fest.
“Looks like an ace to me,” one fan wrote, while another declared, “The most beautiful player on tour.” A third chimed in with a simple but emphatic, “Just incredible.” The post has racked up hundreds of thousands of likes, proving that Kostyuk's appeal extends far beyond the baseline.
A season to remember
Kostyuk's 2025 campaign has been nothing short of spectacular. She captured her first WTA 1000 title in Madrid, then stormed to the semifinals at both Roland Garros and Wimbledon. Her fearless, aggressive style has made her one of the most exciting players to watch, and she's clearly relishing the freedom she's found on court.
“I’m the most happy with the freedom that I gave myself to try different things on the court and just play tennis again,” Kostyuk said after her Wimbledon semifinal loss. “Grass was not my best surface. But I’m super happy with how I deal with the losses. It’s one thing to talk about it but once you lose, it’s how you deal with it.”
She added, “I want to cherish this moment and appreciate how far we’ve all come, me and my team.”
Injury setback
After competing in Guadalajara in mid-September, Kostyuk announced she would be sidelined due to a wrist injury. In an Instagram story, she explained that the pain had worsened despite rest after the US Open, and an MRI confirmed she needed more time to recover. The injury also forced her to withdraw from the Billie Jean King Cup Finals, a decision that clearly pained her.
“It’s always incredibly special, so I’m very sad to miss it,” she wrote.
What's next?
Kostyuk has not yet confirmed whether she'll miss the remainder of the 2025 WTA schedule, including the season-ending WTA Finals. If she does, fans will have to wait until 2026 to see her back in action. But if her Instagram is any indication, she's making the most of her downtime.
This isn't the first time a sports star has caused a stir with a swimsuit snap. Just last week, Sabrina Ionescu's rare swimsuit photo went viral during the WNBA playoffs, and Sophie Cunningham's cheeky swimsuit shot also stole the spotlight. Kostyuk's post is the latest in a long line of athletes showing off their off-court style.
For now, Kostyuk's fans are just happy to see her smiling and enjoying life, even if they're eagerly awaiting her return to the court. As one commenter put it, “Queen of tennis and of Instagram.”
