Hugo Dellien Velasco, born on 16 June 1993, is a professional tennis player from Bolivia. Standing 1.80 meters tall, he plays right-handed with a two-handed backhand and is currently coached by Antonio Pastorino. He achieved a career-high ATP singles ranking of No. 64 on 1 August 2022, becoming the highest-ranked Bolivian player in decades and the current No. 1 player in his country. His career prize money sits at US $3,147,724, reflecting steady progress since turning professional in 2009.
Residing in Buenos Aires, Argentina, Dellien represents Bolivia on the ATP Tour, at the Grand Slams, and in the Davis Cup. His career record, on-court consistency, and ability to break through on clay have made him a respected figure in South American tennis.
Early Life and Background
Hugo Dellien was born in Trinidad, Bolivia, a city in the Beni Department in the country’s northern lowlands. He grew up in a family with strong civic and athletic ties. His father, Hugo Eduardo Dellien, represented the Beni Department as a substitute member of the Chamber of Deputies for the Social Democratic Power alliance from 2006 to 2010, exposing the family to public service alongside sport.
Dellien’s younger brother, Murkel Dellien, is also a professional tennis player and formerly played college tennis at Wichita State University in the United States. The Dellien brothers went on to share a notable slice of Challenger history, becoming the first brothers to win Challenger titles in the same season since the Cerúndolos in 2022. As a young player, Dellien also ran an ice cream business with his father, purchased with some of his early career earnings.
Raised in a country without a long tradition of elite tennis stars, Dellien trained in difficult conditions and built his game on clay, the most common surface in his home region. In juniors, he reached a career-high combined ranking of No. 2 in March 2011, signaling his potential well before his senior breakthrough.
Path to Professional Tennis
Dellien turned professional in 2009 and spent his early years competing on the ITF circuit and ATP Challenger Tour. Working with coach Antonio Pastorino, he developed the patient baseline game and clay-court craft that have become trademarks of his style. He built a strong Challenger resume, capturing 31 singles titles and 18 doubles titles at that level, while gradually earning a regular place in the ATP qualifying draws.
By the late 2010s, Dellien had established himself as Bolivia’s leading player. His Davis Cup record of 26 wins and 10 losses underlines his long-standing role as his country’s singles spearhead. His work on the Challenger circuit laid the foundation for the bigger stages that would follow on the ATP Tour and at the Grand Slams.
Hugo Dellien Career
Early Career (2009–2018)
For nearly a decade after turning professional, Dellien’s main stage was the ITF and Challenger circuits, where he accumulated the bulk of his lower-level titles. Competing mostly on clay in South America, he racked up wins and rankings points that kept Bolivia on the tennis map. By the end of this period, he was ready to test himself against top-level opponents on the ATP Tour.
During these developmental years, Dellien refined the defensive and counterpunching skills that would later frustrate higher-ranked opponents. His partnership with coach Antonio Pastorino, which continues to this day, helped him develop the tactical discipline required to compete week after week on tour.
ATP Breakthrough (2019–2022)
Dellien made his ATP main-draw debut as a lucky loser at the 2019 Córdoba Open. A week later at the 2019 Rio Open, he qualified and then defeated Guido Andreozzi and Roberto Carballés Baena to reach the quarterfinals, recording his first ATP main-draw wins. At the 2019 French Open, he became the first Bolivian player to win an ATP match since Mario Martínez at the same tournament in 1984, completing a comeback against Andreozzi after trailing 3–1 in both sets.
He qualified for the 2021 Italian Open and beat world No. 36 Adrian Mannarino to record his second Masters 1000 win. At the 2022 French Open, Dellien stunned former major champion Dominic Thiem in five sets to earn his second Roland Garros victory. Those results pushed him to a career-high No. 64 in the ATP singles rankings on 1 August 2022, the highest ranking by a Bolivian since Mario Martínez reached No. 60 in November 1983.
Dellien also made his Olympic debut representing Bolivia at the 2020 Summer Olympics in Tokyo, exiting in the first round. Across the Grand Slams, he has reached the second round at the French Open in 2019 and 2022 and at the US Open in 2019, while making first-round appearances at the Australian Open and Wimbledon across multiple years.
Resurgence and Top 100 Return (2023–2025)
After struggling with form and dropping out of the top 150 in May 2023, Dellien used protected ranking entries to stay active on tour. At the 2023 Córdoba Open, he reached his first ATP semifinal, defeating fifth seed Pedro Cachin, Guido Pella, and 2021 champion Juan Manuel Cerundolo. The run made him the first Bolivian tour-level semifinalist since Martínez in Washington in 1983, and he moved back into the top 100 at No. 96 on 27 February 2023.
In 2024, he captured his eleventh Challenger title at the Iași Open in Romania, defeating Javier Barranco Cosano. In 2025, Dellien returned to the top 100 on 21 April at world No. 99. At the 2025 Italian Open in Rome, he entered the main draw as a lucky loser replacing 26th seed Félix Auger-Aliassime, then beat qualifier Thiago Seyboth Wild to reach a Masters third round for the first time in his career.

Notable Events and Milestones
Key career milestones include becoming the first Bolivian to win an ATP match since 1984, his upset of Dominic Thiem at the 2022 French Open, his first ATP semifinal at the 2023 Córdoba Open, and his return to the top 100 in 2025. His career-high No. 64 ranking in August 2022 remains the high-water mark of his career and a source of national pride in Bolivia.
