Gilles-Arnaud Bailly (born 19 September 2005) is a Belgian professional tennis player. He has a career-high ATP singles ranking of No. 201, achieved on 10 November 2025 and a doubles ranking of No. 1,723 reached on 27 February 2023.[1]

Juniors

Bailly had notable results on ITF junior circuit. He was a runner-up at the 2022 French Open and the 2022 US Open in the boys' singles category.[2][3] As a result, he reached an ITF junior combined ranking of world No. 1 on 28 November 2022. Besides that, he became the first boy from Belgium to be crowned a world junior champion by the ITF.[4]

Professional career

2022: ATP Tour debut

Bailly made his debut at the 2022 European Open where he received a main draw wildcard but lost in the first round to compatriot David Goffin despite playing for more than three hours and winning the second set.[5][6]

2023-2025: First Challenger final and ATP win, top 205

Bailly received another invitation at European Open, for the qualies.[7] The following year, he qualified to the main draw of his home tournament but lost to German Daniel Altmaier.[8]

Ranked No. 247, Bailly qualified again for his home event, that edition hosted in Brussels,[9][10] and recorded his first ATP Tour win, over the same player, Altmaier, who defeated him the previous year. He lost to third seed Jiří Lehečka in the second round.[11][12][13] As a result, he moved into the top 235 in the singles rankings and entered the qualification zone of the NextGen Finals. He eventually made it as a first alternate, having been ranked 11th in the race, following the withdrawal of the two top players.[14]

Bailly finished that year at No. 204 in singles, having reached a career-high of world No. 201 the week before.[15] It was the third-largest rankings climb for the 2025 season - behind Rafael Jódar and Petr Brunclík - raising close to 600 positions.[16]
