Wikipedia - Gauthier Onclin
Gauthier Onclin (born 26 February 2001) is a Belgian tennis player who plays mainly on the ATP Challenger Tour. He has a career high ranking of world No. 194 achieved on 18 September 2023.
History
2023: ATP debut in doubles
In January, Onclin reached the semifinals of the 2023 BW Open in Ottignies-Louvain-la-Neuve where he lost to eventual champion and compatriot David Goffin.
In May, he defeated the higher-ranked Elias Ymer at a Challenger event in Bordeaux in the first round. At the 2023 French Open he defeated Nicholas David Ionel in straight sets in the first round of qualifying before losing to Argentine Thiago Agustin Tirante in three sets. Onclin got his revenge over the Argentine in the qualifying at the 2023 Wimbledon Championships, winning in straight sets during his first ever grass-court summer, as his junior years coincided with the grass-court portion of the Tour cancellation due to the COVID-19 pandemic.
In October, he received a wildcard in doubles for the European Open in Antwerp, alongside compatriot Michael Geerts. At the same tournament, in the qualifying singles competition, he defeated higher-ranked American Maxime Cressy.
2024: Maiden Challenger final
In May, Onclin reached his first Challenger final at the Prague Open. He lost to the former world No. 35 Jiří Veselý.
