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]
