Tinne Gilis is one of Belgium's premiere squash players, and has been her nation's no.1 in recent years. She, along with older sister Nele, have been a key fixture of the world's top 25 for a number of years.
Gilis turned professional in 2014, and the year after that, she made her first quarter-final appearance on the tour. The young Belgian made her way into the top 20 during the 2019-2020 campaign, reaching the last 16 of her final three events of 2020 and that run continued into the start of 2021.
She started 2022 with a semi-final appearance at the Cleveland Classic before going on to reach a first platinum level quarter-final at the Allam British Open.
In the summer of 2022, Gilis took the European Individual Championships crown, before starting the new season by reaching the final of the Open de France de Squash, where she was beaten by older sister Nele. She ended the year with a semi-final appearance at the New Zealand Open and also made it into the last eight of the Singapore Open.
The Belgian claimed her first world tour title in early 2023, as she lifted the bronze level Squash On Fire Open trophy. She followed it with a win at the Challenger 30 level Richmond Open, along with reaching the quarter finals of the El Gouna International for the second year in succession, ending her 2022-2023 campaign on a high.
