Wikipedia - Gauthier Onclin
Gauthier Onclin (born 26 February 2001) is a Belgian tennis player. He has a career high ranking of 194 achieved on September 18, 2023.
History
2023
In January 2023 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 2023 he beat the higher-ranked Elias Ymer at a Challenger event in Bordeaux. 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 cancellation due to the COVID-19 pandemic.
In October 2023, 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
In May 2024 Onclin reaches his first final in a Challenger tournament at the Prague Open. He loses to the former world number 35 Jiří Veselý.
