Early Life and Tennis Journey
Mika Stojsavljevic was born on December 15, 2008, in London, to a Serbian father originally from Velika Popina in Croatia and a Polish mother from Warsaw.
She grew up in Ealing, west London, where she attended St Benedict’s School and discovered tennis at the age of seven at Ealing Lawn Tennis Club.
Her early coach, Andrew Lewandowski, was one of the first to spot her potential during sessions at Ealing, describing her enthusiasm and competitive drive as exceptional even at a young age.
Growing up, she idolised Maria Sharapova, whose aggressive baseline game left a visible imprint on her own developing style.
In 2022, she earned a place at Junior Wimbledon qualifying, which put her firmly on the LTA’s radar.
LTA Women’s National Coach Katie O’Brien later described first meeting Stojsavljevic at an inter-regional camp in November 2017 when the player was not yet 10, saying she was always the first to raise her hand and brought a competitive hunger that stood out from the group.
She progressed through the LTA’s national development pathway, eventually moving to train at the Loughborough University National Tennis Academy full-time.
Competing at 14 in the 2023 Wimbledon Junior Girls’ draw, she defeated the fourth seed and reached the quarterfinals — a major signal of what was to come.
In September 2024, Stojsavljevic made history at Flushing Meadows by winning the US Open Girls’ Singles title at the age of 15, defeating Wakana Sonobe of Japan in the final.
She became the first British player to win the junior US Open title since Heather Watson in 2009 and the youngest player since 2006 to claim it.
Professional Tennis Career
Stojsavljevic began competing on the ITF circuit in 2023 at age 14, posting a quarterfinal result at a W25 event in Sunderland as her early career best.
She collected her first professional singles title at the ITF W35 Nottingham event in April 2024, beating several experienced opponents on her way to the trophy.
Her WTA Tour debut came in October 2024, when she received a wildcard into the Toray Pan Pacific Open in Tokyo after her US Open junior title.
She pushed world No. 57 Moyuka Uchijima to a deciding-set tiebreak before falling 4–6, 7–6(7), 7–6(6) in an impressive debut performance.
In 2025, she turned professional and continued building her tour presence. She captured a second ITF singles title at the W35 Birmingham event, reached the final of the W100 Wrexham Open, and made the semifinals at the W100 Dubai.
Her wildcard debut in the Wimbledon main draw that summer — where she faced 31st seed Ashlyn Krueger — gave her a taste of Grand Slam main draw tennis at the highest level.
She carried that momentum into 2026. In April, she made her Billie Jean King Cup debut for Great Britain in the qualifier tie against Australia in Melbourne, defeating world No. 56 Talia Gibson in straight sets and becoming LTA Colour Holder No. 334.
At the Lexus Birmingham Open in June, she became the youngest woman ever to reach the WTA 125 quarterfinals at that tournament with a three-set win over Elvina Kalieva.
She also received a wildcard into the 2026 Wimbledon main draw, where she fell to 11th seed Belinda Bencic in the first round.
Coach
Mika Stojsavljevic is currently coached by Jeremy Bates, as officially listed on her WTA Tour profile.
Bates is a former British No. 1 and Davis Cup stalwart who has significant experience developing British talent within the LTA system. Stojsavljevic trains at the LTA National Tennis Centre in London under this setup.
LTA Women’s National Coach Katie O’Brien has also played a foundational role in her development, guiding her through the junior national pathway from an early age and remaining closely involved in her progression into the professional game.
Earlier in her career, Andrew Lewandowski coached her at Ealing Lawn Tennis Club, where her journey first began.
