Early Life and Background
Elise Mertens was born in Leuven, Belgium, the second daughter of Liliane Barbe, a teacher, and Guido Mertens, who makes furniture for churches. She grew up alongside her older sister, Lauren, who is currently an airline pilot and who introduced the then four-year-old Elise to tennis. This early introduction to the sport sparked a lifelong passion and set the foundation for what would become a remarkable professional career.
Mertens was home-schooled during her formative years and developed a love for languages, becoming fluent in French, English, and Flemish Dutch. Growing up in Belgium, she looked up to compatriots Justine Henin and Kim Clijsters, both former world No. 1 players who inspired a generation of Belgian tennis talent. Mertens herself was a member of the Kim Clijsters Academy, where she trained from 2015 until the academy shut its doors in 2022.
Her early development in the sport was shaped by the strong Belgian tennis tradition and her own dedication to improving her game. The combination of family support, disciplined home-schooling, and access to top-tier coaching helped her transition smoothly into competitive tennis at a young age.
Path to Professional Tennis
Mertens began her journey on the professional circuit in 2013, initially competing in lower-tier events to build her ranking and experience. Her first notable WTA Tour appearance came in doubles at the 2015 Copa Colsanitas, where she partnered with Nastja Kolar. The following year, she claimed her first career doubles title at the 2016 Auckland Open alongside An-Sophie Mestach, signaling her potential as a rising doubles specialist.
In January 2017, Mertens made her breakthrough in singles by winning the Hobart International, defeating Monica Niculescu in the final. This victory propelled her into the WTA top 100 for the first time, marking a significant milestone in her career. Her ability to perform on the big stage was evident early on, and she continued to climb the rankings with consistent performances throughout the year.
Her rapid development caught the attention of the tennis world, and by 2018, she was making deep runs in major tournaments. The foundation laid during her early years, combined with her natural talent and work ethic, prepared her for the challenges of competing at the highest level of professional tennis.

During this period, she focused primarily on doubles play, reaching finals in smaller tournaments and gaining valuable match experience. Her dedication to the sport and consistent improvement allowed her to gradually work her way up the professional ladder.
A significant moment came in 2015 when she made her WTA Tour main-draw debut at the Copa Colsanitas in the doubles event. The following year, she partnered with An-Sophie Mestach to win the doubles title at the 2016 Auckland Open, her first WTA Tour-level title. This early success gave her the confidence and momentum needed to pursue higher-level competition.
Breakthrough Years (2017–2018)
The year 2017 marked Mertens’ arrival as a serious contender in singles. She began the year by winning the Hobart International, her first WTA singles title, which helped her break into the top 100. Throughout the year, she continued to post strong results, reaching new career-high rankings and competing against top players with increasing success.
In 2018, Mertens achieved her greatest singles breakthrough. She became the first woman to win back-to-back titles at the Hobart International, defeating Mihaela Buzărnescu in the final. At the Australian Open, she made her Grand Slam singles debut in spectacular fashion, advancing to the semifinals after defeating top-five player Elina Svitolina in the quarterfinals. She eventually lost to Caroline Wozniacki, but her run made her only the third Belgian woman to reach the last four at the tournament.
Mertens also had a strong doubles season in 2018, winning titles in Wuhan with Demi Schuurs and reaching her career-high ranking of No. 12 in singles. Her success that year established her as a dual threat in both singles and doubles, capable of competing with the best players in the world.
Doubles Dominance and Continued Success (2019–2024)
From 2019 onward, Mertens became increasingly dominant in doubles. Partnering with Aryna Sabalenka, she won the Indian Wells and Miami Open doubles titles in 2019, completing the Sunshine Double. Later that year, the pair won their first Grand Slam doubles title together at the US Open, defeating Victoria Azarenka and Ashleigh Barty in the final. This victory propelled Mertens to a career-high doubles ranking of No. 2 in the world.
In 2021, Mertens reached new heights in her doubles career. She and Sabalenka won the Australian Open, and she later partnered with Hsieh Su-wei to win Wimbledon, her third Grand Slam doubles title. On 10 May 2021, she became the world No. 1 in women’s doubles, becoming the second Belgian player to achieve that ranking after Kim Clijsters. She also won the WTA Finals in doubles alongside Veronika Kudermetova in 2022, becoming the first Belgian to win the season-ending championship.

She reached the final at the Hobart International and won her ninth WTA singles title at the Singapore Open, defeating Ann Li in the final. Later in the year, she won her 10th singles title at the Rosmalen Open, saving eleven match points en route to the championship, equaling a record set in 2001.
In doubles, Mertens partnered with Veronika Kudermetova to reach finals at the Madrid Open and Italian Open.

They capped the season by winning the WTA Finals doubles title in November, defeating Tímea Babos and Luisa Stefani in the final.
Driving Style and Strengths
Mertens is a baseline player whose game blends excellent defensive skills with aggressive shot-making capabilities. Her groundstrokes are hit flat with little topspin, allowing her shots to penetrate deep into the court despite her comparatively slight build. Her backhand is particularly strong and is responsible for the majority of her winners, especially when redirecting power down the line.
One of Mertens’ major weapons is her return of serve, which allows her to neutralize powerful first serves and hit return winners. Her first serve can peak at 119 mph, though her first-serve percentage typically averages around 58%. She compensates with an effective second serve that has tremendous kick. Her superb fitness, stamina, speed, footwork, and court coverage make her one of the most effective counterpunchers on the WTA Tour, capable of turning defense into offense with excellent point construction. Mertens has cited grass as her favorite surface, though the majority of her success has come on hard courts.
Notable Events and Milestones
Among Mertens’ most significant achievements is her ascent to the world No. 1 ranking in doubles on 10 May 2021, making her only the third Belgian to hold a top ranking in either singles or doubles. Her 2018 Australian Open semifinal run marked her arrival as a top singles player, and her six Grand Slam doubles titles place her among the elite doubles players of her era. In 2022, she became the first Belgian to win the WTA Finals in doubles, partnering with Kudermetova.
