Born on September 24, 2001, in Montreal, Canada, Gabriel Diallo is a professional tennis player who stands out both for his imposing physical presence (2.03 m, 100 kg) and his dynamic style of play. The son of a Guinean father and a Ukrainian mother, he proudly embodies a rich multicultural heritage.

​

He began making waves on the Challenger Tour while still competing for the University of Kentucky in the NCAA. In 2022, he captured his first Challenger title in Granby and was part of the Canadian team that won the Davis Cup, a historic achievement for the country.

​

In 2023, Gabriel continued his rise by reaching multiple Challenger finals, claiming a title in Slovakia, and delivering an impressive win over Dan Evans at the Toronto Masters 1000, which helped him enter the Top 130 in the ATP rankings.

​

The year 2024 marked a turning point in his career. He reached the main draw of Roland-Garros for the first time, played a five-set battle in the first round, and later advanced to the third round at the US Open - his best Grand Slam result to date. He also reached the final of the ATP 250 event in Almaty and added a new Challenger trophy to his name in Chicago. In October 2024, he broke into the ATP Top 100.

​

Diallo confirmed his momentum in 2025 with a remarkable run on grass, winning his first ATP title at the Libéma Open in ’s‑Hertogenbosch. A few weeks later, he played a solid Wimbledon campaign, where he reached the second round and pushed world No. 5 Taylor Fritz to five intense sets.
Also, at the Madrid Masters (ATP 1000), as a lucky loser, he stunned Cameron Norrie, saved three match points against Grigor Dimitrov, and reached the quarter-finals of a Masters 1000 for the first time in his career.

 

Known for his booming serve, aggressive baseline game, and composed demeanor, Gabriel is considered one of the most exciting rising talents on the ATP Tour. He trains in Monte-Carlo and continues to refine his all-around game, especially on fast surfaces where his strengths shine through.
