Early Life and Background
Leandro Riedi was born on 27 January 2002 in Frauenfeld, Switzerland, and grew up in Bassersdorf, where he currently resides. He comes from a family with a strong connection to aviation. His parents both worked as flight attendants, a profession his older sister Sarah also pursued. Despite this family background, Riedi gravitated toward tennis from a young age, first picking up a racquet when he was five years old.
His early introduction to the sport laid the foundation for a structured junior career. Standing at 191 cm tall, Riedi developed the physical attributes that would later complement his power-based playing style. Growing up in Switzerland, a country with a rich tennis tradition, gave him access to strong coaching and competitive opportunities from a young age.
Path to Tennis
Riedi’s rise through the junior ranks was swift and impressive. As a junior player, he reached as high as world No. 6 in the combined singles and doubles ITF Junior Circuit rankings, a position he attained on 12 October 2020. His Grand Slam junior results that year foreshadowed his professional potential.
Partnering with Romanian player Nicholas David Ionel, Riedi captured the 2020 Australian Open Boys’ doubles title, defeating Mikołaj Lorens and Kārlis Ozoliņš in the final. Earlier in the season, he reached the boys’ singles final at the 2020 French Open, where he lost to his Swiss compatriot Dominic Stricker. These results established Riedi as one of Switzerland’s most promising young talents heading into the professional ranks.
Leandro Riedi Career
Early Career (2021)
Riedi turned professional in 2021 and immediately began collecting titles on the ITF Men’s World Tennis Tour. He reached five finals that year, winning three titles and finishing as runner-up twice. In May, he claimed his first professional doubles title at the M15 Majadahonda tournament in Spain on clay, partnering with fellow Swiss Dominic Stricker. In October, he won his first ITF singles title at the M15 Selva Gardena tournament in Italy on hard courts.
Later in 2021, Riedi made his ATP main draw debut at the Swiss Open Gstaad after receiving wildcards in both singles and doubles. He competed in doubles alongside Jakub Paul but fell in the singles first round to Federico Delbonis in straight sets. Despite the early loss, the appearance marked his entry onto the ATP stage.
Challenger Breakthrough (2022)
In 2022, Riedi made his first significant marks on the ATP Challenger Tour. In March, he reached both the singles and doubles finals at the Challenger Città di Lugano in Switzerland. That same month, he received a wildcard into the Geneva Open, partnering with Jakub Paul in doubles. He also collected ITF titles at the M25 Trimbach in Switzerland and the M25 Nottingham in the United Kingdom.
The latter half of 2022 proved transformative. In October, Riedi won a Challenger doubles title in Tiburon, California, alongside Valentin Vacherot. In November, he captured the HPP Open Challenger in Helsinki as a qualifier, defeating Dimitar Kuzmanov and Jelle Sels en route to the title, a run that moved him up 80 ranking positions. Finishing the year inside the top 200 at No. 197 on 21 November 2022, Riedi also cracked the top 250 in doubles. The following week, he added another Challenger singles title in Andria, climbing to No. 161 on 28 November 2022.
ATP Tour Establishment (2023)
Riedi entered the top 150 on 9 January 2023 at world No. 135 after reaching a final at the Challenger event in Canberra, Australia. At the 2023 Open 13 Provence in Marseille, he recorded his first ATP Tour-level win against Arthur Rinderknech before falling to eventual champion Hubert Hurkacz. He made his Masters main draw debut at Indian Wells as a qualifier, where he lost to Jack Draper, and reached a new career-high of No. 126 on 20 March 2023.
During the summer, Riedi produced one of his most notable results by upsetting world No. 6 Holger Rune in straight sets at the 2023 Hopman Cup. In October, he received a wildcard for his home tournament, the Swiss Indoors in Basel, but lost to eventual champion Félix Auger-Aliassime. These performances confirmed his growing comfort at the highest levels of the tour.
Top 125 and Injury Setback (2024)
The 2024 season began strongly for Riedi. In January, he won back-to-back Challenger titles, first in Oeiras, Portugal, and then in Ottignies-Louvain-la-Neuve, Belgium. At the Belgian event, he defeated world No. 40 Borna Ćorić in the final, his highest-ranked victory at that point, and returned to the top 175 on 29 January 2024. He continued his ascent to a career-high singles ranking of world No. 117 on 5 August 2024.
His progress was interrupted in September 2024 when he suffered a knee injury that forced an early end to his season. He subsequently underwent surgery, beginning a rehabilitation period that would extend into the following year.
Driving Style and Strengths
Riedi plays an aggressive baseline game well suited to faster surfaces, where his serve and forehand can dictate rallies. His height of 191 cm gives him natural leverage on serve, and his comfort in extended baseline exchanges reflects the tactical grounding he received on the ITF and Challenger circuits. His ability to absorb pressure against top-ranked opponents, as shown in his upset of Holger Rune and his run at the 2025 US Open, points to a maturing competitive temperament.
Notable Events and Milestones
Riedi’s most celebrated moment came at the 2025 US Open, where he became the lowest-ranked player in 25 years to reach the third round of a Grand Slam and the lowest-ranked player to reach the fourth round at the US Open since Jay Berger in 1985. His Grand Slam main draw debut earlier that year at Wimbledon added another milestone to a career defined by steady, patient progression.

He lost in the first round to fellow qualifier and local player Oliver Tarvet but still rose more than 75 positions in the rankings by 14 July 2025.
At the US Open, ranked No. 435, Riedi qualified for the main draw and produced one of the stories of the tournament.
