He has a career-high ATP singles ranking of world No. 116, achieved on 15 June 2026, and a career-high doubles ranking of No. 211, achieved on 6 February 2023.

Early Life and Background
Leandro Riedi was born on 27 January 2002 in Frauenfeld, Switzerland, and was raised in Bassersdorf, where he continues to reside. His parents worked as flight attendants, and his older sister, Sarah, also pursued a career in the same profession. The family environment, focused on service and travel, helped shape his early years and gave him the freedom to explore his own interests.
Riedi first picked up a tennis racquet at the age of five, beginning what would become a defining pursuit in his life. Growing up in Switzerland, he had access to strong local coaching and a competitive junior circuit, and he developed quickly through the country’s established development pathways. Standing 1.91 m (6 ft 3 in) tall, he eventually grew into a player capable of generating significant power from the baseline.
Path to Tennis
Riedi built his game on the ITF junior circuit, compiling a 93–30 singles win-loss record. His first major junior breakthrough came in early 2020, when he partnered with Romania’s Nicholas David Ionel to win the boys’ doubles title at the 2020 Australian Open, defeating sixth seeds Mikołaj Lorens and Kārlis Ozoliņš in the final. Later that season, he reached the boys’ singles final at the 2020 French Open, where he finished as runner-up to fellow Swiss Dominic Stricker in straight sets.
His junior success carried him to an ITF junior combined ranking of world No. 6 on 12 October 2020, confirming his status as one of the most promising young Swiss players of his generation. These results on the international junior stage convinced Riedi and his team that he was ready to turn professional. He made the transition in 2021, beginning his career on the ITF Men’s World Tennis Tour.
Leandro Riedi Career
Early Career (2021)
Riedi’s first full season as a professional was a strong one. He reached five finals on the ITF Men’s World Tennis Tour, winning three titles and finishing as runner-up twice. In May 2021, he claimed his first professional doubles title at the M15 Majadahonda tournament in Spain, partnering with countryman Dominic Stricker. Later in October, he captured his first singles title at the M15 Selva Gardena event in Italy, on hard courts.
That same year, Riedi received a wildcard into both the singles and doubles draws of the 2021 Swiss Open Gstaad, marking his ATP main-draw debut. He lost his first-round singles match to Federico Delbonis in straight sets, but the appearance signaled his arrival on the senior tour and provided valuable experience at ATP level.
Challenger Breakthrough (2022)
In 2022, Riedi transitioned to the ATP Challenger Tour and quickly found success. In March, he reached his first singles and doubles Challenger finals at the 2022 Challenger Città di Lugano in Switzerland. He also received a wildcard into the 2022 Geneva Open, partnering with Jakub Paul in doubles. That March, he also won an M25 title in Trimbach, and in May he added another M25 trophy in Nottingham, United Kingdom.
His biggest Challenger breakthrough came in late 2022. In October, he won the doubles title in Tiburon, California, alongside Valentin Vacherot. In November, he won the 2022 HPP Open Challenger in Helsinki as a qualifier, defeating Dimitar Kuzmanov and Jelle Sels to surge 80 places up the rankings and finish the year inside the top 200 at No. 197 on 21 November 2022. A week earlier he had reached the top 250 in doubles. The following week, he captured his next Challenger singles title in Andria, climbing a further 36 spots to No. 161 on 28 November 2022.
ATP Tour and Masters Debut (2023)
Riedi opened 2023 with another strong Challenger run, reaching the final in Canberra, Australia, to break into the top 150 at world No. 135 on 9 January 2023. At the 2023 Open 13 Provence in Marseille, he recorded his first ATP main-draw win, defeating Arthur Rinderknech before falling to eventual champion Hubert Hurkacz. He made his Masters main-draw debut at Indian Wells as a qualifier, losing to Jack Draper, and reached a new career-high of No. 126 on 20 March 2023.
He also notched a notable upset in July 2023, beating world No. 6 Holger Rune in straight sets at the 2023 Hopman Cup. In October, he received a wildcard into his home event, the 2023 Swiss Indoors, where he lost to fellow wildcard and eventual champion Félix Auger-Aliassime. These results cemented his standing as one of Switzerland’s most promising young players.
Top 125 and Injury Setback (2024)
Riedi began 2024 by winning back-to-back Challenger titles in Oeiras, Portugal, and Ottignies-Louvain-la-Neuve, Belgium. In the latter event, he defeated world No. 40 Borna Ćorić to claim the title, his highest-ranked victory to that point, and returned to the top 175 on 29 January 2024. His progress was halted in September 2024, when he suffered a knee injury that forced an early end to his season. He subsequently underwent surgery to address the issue.
Major Debut and 2025 US Open Run
Riedi underwent another surgery in January 2025 but returned to competition in time to qualify for the 2025 Wimbledon Championships, making his Grand Slam main-draw debut. He lost in the first round to fellow qualifier Oliver Tarvet, but the appearance was a significant personal milestone. He rose more than 75 positions back into the top 500 on 14 July 2025.
His career-defining run came at the US Open later that year. Ranked No. 435, Riedi qualified for the main draw and recorded his first Grand Slam match win over Pedro Martínez. He then upset 19th seed Francisco Cerúndolo in five sets, becoming the lowest-ranked player in 25 years to reach the third round of a major, matching Danny Sapsford’s feat from 1999 Wimbledon. After Kamil Majchrzak retired during their match, Riedi advanced to the fourth round, the lowest-ranked man to reach that stage at a major since Richard Krajicek at 2002 Wimbledon, and the lowest-ranked man to reach the US Open fourth round since Jay Berger in 1985. He returned to the top 175 on 8 September 2025 before falling to Alex de Minaur in the fourth round.
Driving Style and Strengths
Riedi is a 1.91 m right-handed player with a two-handed backhand, allowing him to dictate from the baseline with his height and reach. He has shown particular comfort on hard courts, the surface on which much of his Challenger and Grand Slam success has come. Working with coach Yannik Steinegger, he has built a competitive game around consistency, court coverage, and a willingness to step into the court against higher-ranked opponents.
Notable Events and Milestones
His signature moments include the 2020 Australian Open boys’ doubles title with Nicholas David Ionel, his 2022 Helsinki Challenger title as a qualifier, and his stunning 2025 US Open run from No. 435 to the fourth round. The win over 19th seed Francisco Cerúndolo and the statistical milestones attached to his US Open run place him among the most unlikely late-summer Grand Slam stories of recent years.
