In a historic moment for British tennis, 16-year-old Mika Stojsavljevic will make her professional debut at Wimbledon 2025, and she won’t be alone. She’ll be joined by Hannah Klugman and (Mingge) Mimi Xu, marking the first time this century that three British players under the age of 17 will compete in the women’s singles main draw at SW19.

Mika Stojsavljevic: West London’s 6-Foot Powerhouse

Among the trio, Stojsavljevic stands out for her results, with a playing style that resembles that of her childhood idol, Maria Sharapova. She captured the 2024 US Open girls’ title, upsetting Wakana Sonobe in straight sets. Becoming the youngest player to win a junior Grand Slam since 2006, the third youngest British girl this century to achieve the feat and the first British girl to win a US Open in 15 years.

Born to a Serbian father and Polish mother, the six-foot-tall Stojsavljevic trains at the LTA’s National Academy in Loughborough, where she balances elite tennis with full-time academics. Remarkably, she sat for her GCSE exams during the ITF W35 Nottingham event and still came away with her first professional title.

Now ranked No. 796 on the WTA Tour, the West London native steps onto Centre Court with the spotlight squarely on her. Her wildcard entry into Wimbledon 2025 comes as no surprise, following a joint effort by the LTA and the All England Club to promote rising British talent. Stojsavljevic has already offered a preview of her promise, reaching the junior quarterfinals at Wimbledon in 2023.

Klugman and Xu: Bright Sparks from the Same Fire

Joining Stojsavljevic in the Wimbledon main draw are Hannah Klugman and Mimi Xu, both making waves in their own right.

Klugman, 16, became the first British girl in nearly 50 years to reach the French Open junior final, adding to her 2023 Orange Bowl title. Forgoing the LTA’s academy system, she trains locally at Reed’s School under Ben Haran. With a crisp baseline game and sharp touch at the net, she’s postponed her GCSEs to November to focus solely on tennis this summer.

Xu, 17, is the most seasoned of the three and is termed “super intelligent” by Brit Captain Anne Keothavong. Ranked No. 302, the Welsh teenager recently stunned world No. 52 Alycia Parks on her way to the Birmingham quarterfinals. Coached by Katie O’Brien and Nigel Sears, Xu blends tactical with academic discipline, even squeezing in A-Level biology exams between matches at Birmingham and Nottingham.

Age Limits, Tour Rules, and the Road Ahead

Teenage players face restrictions on how many tournaments they can enter and at what level before turning 16. Under current WTA rules, they’re limited to 12 events across all tiers after their 16th birthday, with that cap expanding at 17. With their Wimbledon wildcards, Stojsavljevic, Klugman, and Xu will take home £66,000 in prize money, along with the Grand Slam experience.

The head of women’s tennis for the LTA, Iain Bates, stated to BBC Sport, “All three are on different paths to the top of the game. But their progress shows they are a pack of players. That is the most positive sign right now. Winning and going far in junior Grand Slams is a massive achievement, but having your friends and peers pushing you to go to the next stage is even more important.

If you look at their profiles in isolation, you would say all of them are ready for the opportunity to play. “As I told them all, I hope and anticipate they will have many more Wimbledons. The first one is about showing their level and competing against some of the best in the world. I think this is the right opportunity and the right time for them.”

I’m an academic turned sports writer from Raipur, India, specializing in the NFL, MMA, and tennis at The Playoffs. I previously wrote for Sportskeeda and hold a B.A. and M.A. in History. My journey into sports media began far from the field, rooted in the arts and sciences. Funny enough, I didn’t grow up a sports fan; I used to see it all as just noise. But a fateful writing job introduced me to the world of sports, and what began as a gig quickly became a passion. I understood those voices aren’t noise; they’re emotions of true sports fans, and now I am one of them, writing with the same energy I once questioned.
