History
After winning the title of the men's doubles of the Nottingham Open alongside Jacob Fearnley, the pair received wildcards for the 2023 Wimbledon Championships. He was also given a wildcard into the men's qualifying singles and beat Mili Poljicak before pushing the experienced Radu Albot to three sets. In the doubles, he and Fearnley beat Andre Goransson and Ben McLachlan in the opening round before losing to Matthew Ebden and Rohan Bopanna.
He won three consecutive singles titles on the ITF tennis tour in October 2024. His haul included the singles and doubles titles at the M25 Louisville, a singles victory in Norman, Oklahoma, and a singles victory in Harlingen, Texas.
He began 2025 with another title at that level in Sunderland before adding a fifth in six months in Bakersfield, United States in March 2025, defeating American Alex Rybakov in the final 6-2, 6-4 to seal the title.
