He has a career-high ATP singles ranking of world No. 18, achieved on 24 June 2024, and a doubles ranking of No. 189, achieved on 29 July 2024.

Standing 170 cm tall, he competes primarily on clay courts and has established himself as one of the leading South American players of his generation.
Early Life and Background
Sebastián Báez was born on 28 December 2000 in Buenos Aires, Argentina. He grew up in the Argentine capital and currently resides there as well. From an early age, Báez gravitated toward tennis, training in a country with a rich tradition of producing clay-court champions. Argentina has long been a hotbed for talented players, and Báez developed his game within that competitive environment, refining the aggressive baseline style that would later define his professional career.
As a junior, Báez quickly made his mark on the international scene. He became the top-ranked junior in the ITF combined ranking on 12 March 2018, signaling his potential to transition successfully to the professional ranks. That same year marked the beginning of his journey toward the ATP Tour, as he began entering professional events while still competing in junior tournaments.
Path to Tennis
Báez turned professional in 2018 and initially competed on the ITF Futures circuit and ATP Challenger Tour, where he built his ranking through consistent results. His breakthrough on the Challenger circuit came in 2021, when he became the youngest player in history to claim five ATP Challenger Tour titles in a single season. He lifted trophies in Concepción, Santiago, Zagreb, a second Santiago event, and Buenos Aires, defeating opponents including Francisco Cerundolo, Tomás Barrios Vera, Juan Pablo Varillas, Felipe Meligeni Rodrigues Alves, and Thiago Monteiro.
That same year, Báez qualified for the 2021 Next Generation ATP Finals in Milan after Jenson Brooksby’s withdrawal due to an abdominal injury. He advanced to the semifinals with wins over third seed Lorenzo Musetti and eighth seed Hugo Gaston before falling to top seed Carlos Alcaraz. By winning his sixth Challenger title in Campinas, Brazil, Báez reached the top 100 for the first time, finishing 2021 at World No. 97 in the ATP year-end rankings.
Sebastian Baez Career
Early Career (2018–2020)
Báez began his professional career on the ITF Futures circuit in 2018, the same year he rose to the top of the ITF junior combined rankings. During this developmental phase, he focused on gaining match experience and building the physical foundation required for the professional game. His results on the lower-tier circuits earned him opportunities to test himself against higher-ranked opponents in Challenger events.
By the end of 2020, Báez had assembled a strong record on the Challenger circuit, setting the stage for his rapid ascent in 2021. His combination of heavy topspin, court coverage, and competitive temperament made him well-suited for clay-court tennis, the surface on which he would earn most of his early success.
ATP Breakthrough (2021–2022)
Báez made his ATP debut at the 2021 Chile Open, where he lost to Holger Rune in straight sets. He earned his first tour-level win at the 2021 Hamburg European Open, defeating Corentin Moutet in the first round. These early appearances helped him adjust to the speed and pressure of ATP-level competition.
In 2022, Báez announced himself as a rising star 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 facing World No. 4 Stefanos Tsitsipas in the second round. He reached his maiden ATP Tour final at the 2022 Chile Open as the seventh seed, losing to Pedro Martínez. The following week at the 2022 Estoril Open, Báez won his maiden ATP title, defeating third seed Frances Tiafoe to move into the top 40. He also reached the final at the 2022 Swedish Open in Båstad, where he lost to compatriot Francisco Cerúndolo after defeating top-10 player Andrey Rublev in the semifinals. By 18 July 2022, he had reached a career-high ranking of No. 32.
Rising Contender (2023–2024)
In February 2023, Báez won the second title of his career at the Córdoba Open, defeating Luciano Darderi, Tomás Barrios Vera, Hugo Dellien, and compatriot Federico Coria on clay. He reached the top 30 on 17 April 2023 following the Monte-Carlo Masters. In August, he won two more titles as part of a ten-match winning streak, capturing the Austrian Open Kitzbühel on clay by defeating Dominic Thiem in the final, and the Winston-Salem Open on hardcourts by defeating Jiří Lehečka in straight sets. At the US Open, he reached the third round of a Major for the first time, defeating 27th seed Borna Ćorić and Felipe Meligeni Alves before losing to eventual finalist Daniil Medvedev.
In 2024, Báez reached a Grand Slam third round at the Australian Open for the second time, moving into the top 25. At the 2024 Rio Open, he won his fifth and biggest title, defeating compatriot Mariano Navone in the final to reach a new career-high of world No. 21. The following week at the 2024 Chile Open, he won his sixth title by defeating Alejandro Tabilo, becoming the Latin American No. 1 player at world No. 19 on 4 March 2024, overtaking Francisco Cerúndolo. He was one of only 20 Argentines ever to reach that ranking.
2025 Rio Champion Era (2025–Present)
Seeded fifth at the 2025 Rio Open, Báez reached back-to-back finals, becoming just the third player to reach multiple finals in tournament history after Diego Schwartzman and Carlos Alcaraz. He successfully defended his title against Alexandre Muller, becoming the first Rio champion to win the title twice and in consecutive years. At the next Golden Swing tournament, the 2025 Chile Open, Báez reached back-to-back finals, recording his 100th career win over compatriot Camilo Ugo Carabelli. He became the first South American born in the 2000s to accomplish that feat.

His aggressive court positioning and ability to construct points with patience and precision make him a formidable opponent on slower surfaces.
