He has a career-high doubles ranking of World No. 18, achieved on 25 September 2023, and a career-high singles ranking of World No. 574, reached on 24 December 2018. Standing 6 ft 1 in (185 cm) tall and playing right-handed with a one-handed backhand, Gillé has built his career around consistency and partnership chemistry on the ATP Tour.
Resident in his hometown of Hasselt, Belgium, Gillé has become one of the country’s most reliable doubles competitors. He has won eight ATP Tour doubles titles, including a prestigious ATP Masters 1000 crown, and has represented Belgium in team competition and the Olympic Games. His steady rise through the rankings reflects a player who has steadily improved by working with a regular partner and competing across the global circuit.
Early Life and Background
Sander Gillé was born on 15 January 1991 in Hasselt, a city in the Limburg province of Belgium. Growing up in Hasselt, he was introduced to tennis at a young age and developed his game within the Belgian sporting system. Belgium has produced a long list of notable tennis players, and Gillé’s hometown of Hasselt offered him access to local clubs and competitive junior events that helped shape his early development as a doubles specialist.
During his formative years, Gillé trained in Belgium before continuing his education in the United States. He attended East Tennessee State University (ETSU), where he played college tennis and refined the tactical and technical elements of his game. College tennis in the NCAA system provided him with high-level match experience, structured training, and exposure to a wide range of playing styles that would later prove valuable on the ATP Tour.
Path to Professional Tennis
After his college career at ETSU, Gillé turned professional in 2013 and began competing on the ATP Challenger Tour and ITF Futures circuit. The early years of his professional career were spent building his ranking, gaining experience on different surfaces, and learning how to navigate the demanding travel schedule of the international tour. His doubles focus began to take shape during this period, as he recognized that his game style and instincts were well suited to the format.
A key turning point in Gillé’s career came when he began partnering with fellow Belgian Joran Vliegen. The duo quickly developed a strong on-court rapport, and their partnership became the foundation of Gillé’s rise up the doubles rankings. Working together, they combined Gillé’s steady baseline play and net coverage with Vliegen’s aggressive returning and serving, creating a balanced team that troubled higher-ranked opponents. Their success at Challenger-level events paved the way for breakthrough moments on the main ATP Tour.
Sander Gillé Career
Early Career (2013–2018)
Following his decision to turn professional in 2013, Gillé spent his first several seasons competing primarily on the Challenger and Futures circuits. He played a limited number of singles matches at the top level, recording a career-high singles ranking of World No. 574 on 24 December 2018. Doubles, however, became his primary focus, and he gradually accumulated experience and points by working with a variety of partners.
During these developmental years, Gillé built the foundation for his later success by competing week in and week out on the lower tiers of professional tennis. The grind of the Challenger circuit taught him resilience, surface adaptability, and the importance of match fitness. By the end of 2018, he was ready to test himself more consistently on the ATP Tour, setting the stage for a rapid rise once he found his long-term partnership.
ATP Tour Breakthrough (2019–2021)
The year 2019 marked a major breakthrough for Sander Gillé on the ATP Tour. Partnering with Joran Vliegen, he won his first ATP Tour doubles title at the Swedish Open, followed a week later by a second title at Gstaad. The pair built an 11-match winning streak during this stretch before falling in the final at Kitzbühel, and they added a third title later in the season at the Zhuhai Championships.
In 2020 and 2021, Gillé and Vliegen continued their upward trajectory. They captured titles at the 2020 Astana Open and the 2021 Singapore Open, and they reached the quarterfinals at the 2020 US Open, their best Grand Slam result to that point. At the 2021 Madrid Open, the pair advanced to their first Masters 1000 semifinal, and as a result, Gillé reached a career-high ranking of No. 33 on 10 May 2021.
Top 20 and Masters Title Era (2023–2024)
In 2023, Gillé achieved his biggest Grand Slam result, reaching the final of the French Open with Vliegen as an unseeded team. The pair defeated several seeded opponents, including fourth-seeded Nikola Mektić and Mate Pavić, before falling in straight sets to Ivan Dodig and Austin Krajicek in the championship match. Later that summer, Gillé made his top 20 debut on 7 August 2023, and by September he had climbed to a career-high No. 18 in the world.
The 2024 season brought Gillé his most prestigious title to date. At the 2024 Monte-Carlo Masters, he and Vliegen won their first ATP Masters 1000 title, defeating notable pairs along the way, including third-seeded Horacio Zeballos and Marcel Granollers in the semifinals, and an alternate duo of Alexander Zverev and Marcelo Melo in the final. The victory made Gillé and Vliegen only the second and third Belgians to win a Masters 1000 doubles title, following Xavier Malisse’s win at Indian Wells in 2010.
2025 Season and New Partnership
In 2025, Gillé began a new chapter in his career, forming a partnership with Polish player Jan Zieliński while continuing selective appearances with Vliegen. At the 2025 Australian Open, he reached the third round in men’s doubles. He and Vliegen also represented Belgium at the 2024 Olympic Games in Paris, exiting in the first round of the men’s doubles draw.
As of late October 2025, Gillé’s current doubles ranking stood at No. 56, reflecting a transitional period as he builds a fresh partnership. He has continued to compete in mixed doubles at Grand Slams, reaching the quarterfinals at the 2024 US Open and the 2024 Australian Open. With eight ATP doubles titles already secured, Gillé remains a respected figure on the doubles circuit and a key member of Belgium’s tennis community.
