Francisco Comesana Bio
Francisco Comesaña, born on 6 October 2000, is an Argentine professional tennis player who competes on the ATP Tour. He has built his reputation on a strong baseline game and a willingness to take on the sport’s biggest names, including a career-defining upset of world No. 2 Alexander Zverev in 2025. Standing 1.78 m (5 ft 10 in) tall and playing right-handed with a two-handed backhand, Comesaña reached a career-high ATP singles ranking of world No. 54 on 18 August 2025. He also achieved a career-high doubles ranking of No. 257 on 8 May 2023, and currently resides in Buenos Aires, Argentina.
Early Life and Background
Francisco Comesaña was born in Mar del Plata, in the Buenos Aires Province of Argentina, to his father Agustín and his mother Adela. His surname points to a family heritage with roots in Galicia, a region in northwestern Spain known for producing generations of emigrants to South America. He grew up alongside his brother Valentín, in a household where sport was part of everyday life.
He first picked up a tennis racket at around the age of six, and his early development took place at the Edison Lawn Tennis club in Mar del Plata, a club owned by the family of Argentine doubles specialist Horacio Zeballos. The coastal city and its tennis community gave him a steady base to refine his fundamentals and to compete in junior events. By his late teens, Comesaña was ready to take the next step in his training, eventually leaving Mar del Plata to chase a more demanding competitive schedule.
Path to Professional Tennis
In 2021, at the age of twenty, Comesaña moved to Córdoba to train under coach Facundo Argüello, a shift that marked his transition from promising junior to full-time professional. The move placed him in a more competitive training environment and helped him adjust to the rigors of the professional circuit. Two years later, in 2023, he relocated again, this time to Buenos Aires, where he began working with coach Sebastián Gutiérrez at the Club de Gimnasia y Esgrita de Buenos Aires. That partnership has remained central to his development, providing both tactical guidance and a high-level practice environment in the Argentine capital.

Early Career (2022–2023)
Comesaña opened his professional account on the ATP Challenger Tour in May 2022, when he won his first Challenger-level doubles title in Vicenza, Italy, partnering Italy’s Luciano Darderi. The victory signaled that he was ready to compete at a higher level. The following month, he strung together back-to-back singles titles on home soil, winning both the Corrientes Challenger and the Challenger Tenis Club Argentino, defeating compatriot Mariano Navone in both finals.
His 2023 season brought further progress. He reached the final of the Macedonian Open in May, falling to Máté Valkusz, before winning the Internazionali di Tennis Città di Vicenza the following week with a victory over Pablo Llamas Ruiz. He added a fourth Challenger title later in the year at the Svijany Open and reached another final at the Santa Cruz Challenger, confirming his place among the most consistent performers on the Challenger circuit.
ATP Tour Breakthrough (2024–2025)
Comesaña made his ATP Tour debut in February 2024 at the Córdoba Open as a wildcard, falling in the first round to compatriot Thiago Agustín Tirante. He followed that with a qualifying appearance at the Rio Open, an ATP 500 event, where he lost in the first round to fourth seed Francisco Cerúndolo. He then entered the Chile Open as a lucky loser and was eliminated in the opening round by Juan Pablo Varillas. After winning the Challenger title at the Open de Oeiras, he cracked the top 100 for the first time on 22 April 2024.
Ranked No. 122, Comesaña announced himself on the Grand Slam stage at Wimbledon, where he stunned sixth seed Andrey Rublev in the first round, his first ATP-level win, his first Major win, and his first victory over a top-10 player. He followed that with a win over Adam Walton to reach the third round before falling to 25th seed Lorenzo Musetti in four sets. At his US Open debut later that summer, he again reached the third round, beating Dominic Stricker and upsetting 17th-seed Ugo Humbert along the way. In October 2024, he won his second Challenger title of the season at the Challenger de Buenos Aires on his 24th birthday.
The 2025 season elevated his profile further. At the Rio Open, he reached his first ATP Tour quarterfinal by defeating wildcard Gustavo Heide and sixth seed Nicolás Jarry in a pair of three-set marathons, saving a match point against Jarry. He then produced the biggest win of his career by upsetting world No. 2 and top seed Alexander Zverev in the quarterfinal, rallying from 1-4 down in the final set to reach his first ATP semifinal, where he fell to Alexandre Müller. He made his Masters 1000 debut at the 2025 Miami Open as a qualifier and later reached the fourth round of a Masters for the first time at the 2025 Cincinnati Open, defeating 29th seed Luciano Darderi by retirement and Reilly Opelka.
Grand Slam Performances (2024–2026)
Comesaña’s Grand Slam résumé includes a third-round showing at Wimbledon in 2024 and a third-round run at the US Open the same year. In 2025, he added first-round exits in doubles at the Australian Open, French Open, and Wimbledon. The 2026 season opened with a second-round appearance at the Australian Open, followed by a career-best third round at the French Open, where he defeated seeded player Luciano Darderi before losing a five-set, five-hour-plus battle to Matteo Berrettini in a final-set tiebreak.
Driving Style and Strengths
Comesaña plays a right-handed game built on a solid two-handed backhand and a willingness to extend rallies. His results suggest particular comfort on clay, where his baseline consistency and court craft have produced his deepest runs, including his 2026 French Open third round. His conditioning has been tested in marathon matches, with several of his biggest wins coming in deciding sets and third-set tiebreaks, pointing to a player whose competitive endurance is among his defining tools.
Notable Events and Milestones
His signature moment to date remains the 2025 Rio Open quarterfinal, where he defeated world No. 2 Alexander Zverev to reach his first ATP semifinal. Equally memorable was his first-round upset of Andrey Rublev at Wimbledon in 2024, which marked his first top-10 victory and his first Grand Slam win. His five-hour, third-round loss to Matteo Berrettini at the 2026 French Open stands as one of the most grueling matches of his career.
