He reached a career-high ATP singles ranking of world No. 18 on 24 June 2024 and a best doubles ranking of No. 189 on 29 July 2024. As of mid-2026, he holds seven ATP Tour singles titles and is widely regarded as one of the leading Argentine players of his generation.

He represents Argentina in Davis Cup competition and is currently based in Buenos Aires. His coach is Sebastián Gutiérrez, and his career prize money on the ATP Tour has surpassed US $6.7 million.

Early Life and Background

Sebastián Báez was born and raised in Buenos Aires, Argentina, a city with a deep tradition in South American tennis. Growing up in Argentina gave him early and frequent access to clay courts, the surface that would later define much of his professional success. From a young age, Báez showed the kind of competitive drive and consistency that Argentine tennis is known for, training in a country that has produced multiple Grand Slam champions.

As a junior, Báez quickly rose through the ranks. He reached the world No. 1 combined ITF junior ranking on 12 March 2018, a clear sign of his potential. That same year, he made the decision to turn professional, beginning a steady climb from the ITF Futures circuit up through the ATP Challenger Tour. His early development laid the groundwork for a smooth transition into the upper levels of professional tennis.

Path to Tennis

Báez began his professional journey on the ITF Futures and World Tennis Tour circuits, where he collected five singles titles and three runner-up finishes. Those results earned him entry into ATP Challenger events, where his game continued to mature. The Challenger level proved to be a key proving ground, allowing him to test his game against experienced competitors and build the consistency needed for the ATP Tour.

His big breakthrough at the Challenger level came in 2021, when he won six Challenger titles in a single season, becoming the youngest player in history to claim five ATP Challenger Tour titles in a year. Among his victories were titles in Concepción, Santiago, Zagreb, a second Santiago event, and Buenos Aires. Later that year, he added a sixth Challenger crown in Campinas, Brazil, which pushed him into the ATP top 100 for the first time at world No. 97 in the year-end rankings.

Sebastián Báez Career

Early Career (2018-2020)

After turning professional in 2018, Báez spent his first full seasons competing on the ITF Futures circuit, where he built his match toughness and accumulated five ITF singles titles. The COVID-19 pandemic disrupted much of the 2020 calendar, but Báez used that period to refine his game and prepare for a return to competition. His results on the lower-tier circuits gave him the ranking points needed to enter higher-level Challenger events.

By the end of 2020, Báez had positioned himself as one of Argentina’s most promising young players. His right-handed baseline game, built around heavy topspin and solid court coverage, was particularly well suited to clay. These early years were essential in establishing the work ethic and tactical discipline that would later fuel his rise on the ATP Tour.

ATP Breakthrough (2021-2022)

Báez made his ATP Tour debut at the 2021 Chile Open, where he lost to Holger Rune in straight sets. He earned his first tour-level victory at the 2021 Hamburg European Open, defeating Corentin Moutet in the opening round. His rapid rise continued when he qualified for the 2021 Next Generation ATP Finals in Milan, where he advanced to the semifinals with wins over Lorenzo Musetti and Hugo Gaston before losing to top seed Carlos Alcaraz.

The 2022 season marked Báez’s true arrival on the ATP Tour. He made his Grand Slam debut at the 2022 Australian Open, defeating Albert Ramos Viñolas for his first major win before a competitive loss to Stefanos Tsitsipas. Later that year, he reached his maiden ATP final at the 2022 Chile Open, where he lost to Pedro Martínez. He captured his first ATP title at the 2022 Estoril Open, defeating Frances Tiafoe in the final and moving into the top 40. By mid-2022, he had reached a career-high ranking of No. 32 and was consistently competing in the late rounds of clay-court events.

Multiple Titles and Top 30 (2023)

In 2023, Báez added three more ATP singles titles to his resume. He opened the year by winning the Córdoba Open on clay, defeating Federico Coria in the final. He followed that with a straight-sets victory over Dominic Thiem to win the Austrian Open Kitzbühel, then captured the Winston-Salem Open on hardcourts by beating Jiří Lehečka. These results pushed him into the top 30 of the ATP rankings for the first time.

At the 2023 US Open, Báez advanced to the third round of a Grand Slam for the first time, defeating Borna Ćorić before falling to Daniil Medvedev. The 2023 season also included a 12-match winning streak, the longest of his career to that point, which underlined his growing consistency across both clay and hard surfaces.

Río Repeat Champion Era (2024-2025)

The 2024 season was a landmark year for Báez. After reaching the third round of the 2024 Australian Open, he won the biggest title of his career at the 2024 Rio Open, defeating compatriot Mariano Navone in the final. The following week, he captured the 2024 Chile Open, defeating Alejandro Tabilo. With those results, he became the Latin American No. 1 player, reaching a career-high ranking of world No. 18 in June 2024. He was one of only 20 Argentine players ever to reach the top 20.

In 2025, Báez successfully defended his Rio Open title, defeating Alexandre Müller in the final to become the first player to win the Rio title twice and in consecutive years. At the 2025 Chile Open, he reached the back-to-back final, recording his 100th career ATP win in the process and becoming the first South American born in the 2000s to reach that milestone. His continued success on clay has cemented his place among the leading players of the South American circuit.
