Playing style

[edit]
Gaston playing a drop shot at the 2018 Summer Youth Olympics

Gaston is known for his unique and unorthodox style of play. He is left-handed and utilizes the wide serve on the advantage court like many left-handed players. Gaston weaponizes dropshots often in his matches. He is known to hit dropshots after bringing his opponent out wide with his serve, to make them cover more of the court. After his fourth round loss to Dominic Thiem, Gaston said "I love to do some dropshots. But I can do all the shots in my game, so it's important to change".[51] Thiem said of him "I haven't seen in a very long time a player with such a big touch in his hands, his dropshots are just from another planet".[52] Gaston has a varied playing style and hits sliced forehands as well as backhands to destabilize his opponents. His favourite surface is clay and his backhand is his favourite groundstroke.[53][54]

Early life

Family and background

Hugo Gaston was born on September 26, 2000, in , . His parents, Thierry Gaston and Fabienne Gaston, both work for the aircraft manufacturer , based in the Toulouse region. Thierry served as president of the Fonsorbes Tennis Club, where the family was actively involved in the sport. Gaston's older brother, Anthony, also employed by , shares the family's passion for . Raised in a tennis-enthusiast household in , Gaston was introduced to the game through casual family matches, including games with his older brother against the walls of their living room. He began playing at age two at the local Fonsorbes club, reflecting the supportive environment provided by his family during his early years in the area.

Early tennis development

Hugo Gaston first encountered at the age of two, introduced to the sport through his family's enthusiasm in their home in , . He began practicing informally by hitting balls against the walls of the family living room alongside his older brother, fostering an early affinity for the game. His father, Thierry Gaston, played a pivotal role by serving as president of the Fonsorbes Tennis Club, located about 20 kilometers from , which provided immediate access to facilities and immersed the young Gaston in a tennis-oriented environment from the outset. Gaston's initial formal training commenced around age six at the Fonsorbes club under local coach Marc Barbier, marking the transition from casual play to structured skill development. As a natural left-handed player, he benefited from coaching that emphasized his innate advantages, such as improved angles on groundstrokes, while building foundational techniques like footwork and ball control tailored to a young athlete. The family's collective involvement— with both parents and his brother also playing tennis—reinforced consistent practice and motivation, helping Gaston refine basic skills through regular club sessions. By his early years, Gaston started participating in local youth tournaments in the Toulouse region, gaining competitive experience that honed his left-handed style and prepared him for more advanced junior levels. These early matches, supported by the club's resources, allowed him to adapt standard youth equipment, such as smaller racquets suited for juniors, to his developing game without major modifications. Local coaching focused on progressive drills to nurture his creativity on court, laying the groundwork for his distinctive shot-making abilities.

Gaston's ATP Tour debut came in February 2018 at the in , where he entered the main draw as a wildcard but fell in the first round to , 4-6, 3-6. Later that year, he received a wildcard for the qualifying draw at his home Grand Slam, the , but was eliminated in the first qualifying round by Jürgen Zopp, 5-7, 6-4, 6-2. These initial ATP-level appearances exposed him to higher-pressure environments, though he struggled with serve consistency and adapting to faster indoor hard courts compared to his preferred clay surface. By 2019, Gaston had progressed to the ATP Challenger Tour, where he achieved greater stability on clay. He captured his maiden Challenger title at the Open in June, overcoming compatriot 6-3, 6-3 in the final to earn 100 ranking points. He also competed at the Quimper Challenger in January, losing in the first round to Daniel Brands in straight sets, 2-6, 6-7(3). These results highlighted his growing affinity for clay, though he faced adaptation hurdles on indoor hard courts, such as at the Challenger, where early exits underscored the need for a more versatile return game. Representative examples like demonstrated his ability to construct points patiently from the backcourt, a style honed during his junior years. Gaston's steady Challenger progress fueled a significant ranking ascent, starting the year outside the top 500 at No. 418 and concluding 2019 at No. 137 after accumulating points from multiple deep runs. This climb reflected his maturation in handling three-set matches and multi-week schedules, though challenges persisted in transitioning between surfaces, particularly the quicker pace of hard courts that tested his defensive positioning. By year's end, he had played predominantly on clay (16-3 record), using it to build confidence before venturing more into varied conditions.

2020: Major debut and French Open breakthrough

Gaston's 2020 season was heavily impacted by the , which suspended the from March to August, limiting opportunities following his early-year appearances. He made his Grand Slam debut at the Australian Open in January as a wild card, defeating qualifier in the first round before losing in the second round to , 0-6, 3-6, 1-6.

Following his breakthrough at the , he secured direct entry into several tournaments, marking his first full year of regular ATP-level competition. His progress was highlighted by a career-best run at the Swiss Open in , where, as world No. 155, he advanced to his maiden ATP final by defeating higher-ranked opponents, including in the quarterfinals (6-4, 1-6, 7-6(11)) and defending champion in the semifinals (1-6, 6-3, 7-5). In the final, he fell to top seed 6-3, 6-2, earning 150 ranking points and propelling him into the top 100 for the first time. Gaston's form extended to the ATP Masters 1000 level later in the year, where he qualified for the and produced one of his standout results. As a qualifier ranked No. 103, he upset 12th seed in the second round (6-7(3), 6-4, 7-5) before defeating emerging star 6-4, 7-5 in the round of 16, saving set points in a tense encounter. This propelled him to the quarterfinals, where he lost to world No. 2 7-6(5), 6-4, securing his best Masters 1000 result to date and further solidifying his top 100 status. These achievements contributed to 44 match wins across the season, including multiple three-set victories that showcased his resilience and baseline aggression.

These results marked his first second-round appearance at a major outside Roland Garros, reflecting improved adaptability on hard courts. By season's end, Gaston's 2021 campaign yielded a year-end of No. 67, a jump of over 90 spots from the previous year, earned through 44-30 overall record and $818,904 in prize money. He maintained momentum with a spot in the Next Gen ATP Finals in , where he competed against top under-21 talents despite a group-stage retirement injury. No major coaching changes occurred during the year; Gaston continued working with long-time coach Marc Barbier, whose guidance emphasized tactical variety on clay, aiding his breakthrough on that surface where he won 70% of matches. This period established Gaston as a rising French talent, blending defensive solidity with opportunistic net play.

2022: Grass and hard court debuts, career-high ranking

In 2022, Gaston made his debut on grass courts, beginning with the Libéma Open in 's-Hertogenbosch, where he reached the quarterfinals by defeating Soonwoo Kwon in the first round 6-3, 6-7(5), 6-4 and eighth seed in the second round 3-6, 6-3, 7-5, before falling to wildcard 7-6(2), 6-4. This marked a promising start to his grass-court experience, showcasing his adaptability with drop shots and defensive play on the quicker surface. At Wimbledon, in his Grand Slam grass debut, he advanced to the second round with a five-set victory over 6-2, 4-6, 0-6, 7-6(6), 6-3, but was defeated by 27th seed 7-6(4), 6-4, 6-4. Transitioning to hard courts later in the year, Gaston entered the US Open main draw directly for the first time, but struggled with the pace, losing in the first round to 1-6, 4-6, 2-6 after failing to convert break opportunities. His hard-court adaptation showed mixed results in ATP events, including a first-round exit at the Rolex Paris Masters to Marc-Andrea Hüsler 3-6, 6-3, 7-6(5), though he secured a notable qualifier win over en route.

These non-clay performances contributed to significant ranking progress, as Gaston entered the top 60 for the first time following his Wimbledon run and peaked at a career-high No. 58 on , 2022, bolstered by his grass-court successes and prior clay stability. Key wins like over Brooksby (then ranked No. 40) highlighted his potential on faster surfaces, yet challenges persisted in maintaining consistency, with early hard-court exits revealing difficulties in serve reliability and net approaches against aggressive opponents.

2023: Form struggles and controversy

Gaston's 2023 season was marked by a significant dip in form, contrasting his career-high ranking of No. 58 achieved in 2022. He struggled with consistency on the , posting an 8-18 win-loss record in main draw matches and failing to advance beyond the second round in any event. This poor performance led to a drop outside the top 100 during the year, with his ranking ending at No. 96 by December. Early exits plagued his Grand Slam appearances, including a first-round defeat at the French Open to Alex Molčan, 6-1, 7-6(4), 6-4, despite entering as a wildcard on home clay. Similar results followed at other majors and Masters 1000 events, such as a second-round loss to Borna Ćorić at the Madrid Open and a second-round exit at the US Open to Laslo Djere. These setbacks were attributed to tactical inconsistencies and inability to maintain baseline rallies, rather than specific injuries or fatigue. To rebuild his ranking, Gaston turned to the Challenger circuit, where he showed flashes of recovery by securing two titles: the Iasi Open in July, defeating 3-6, 6-0, 6-4 in the final, and the Open later that month, overcoming 6-3, 5-7, 6-2. However, these successes were isolated, as he suffered additional early defeats in other Challengers, limiting his overall momentum and preventing a sustained return to the top 100. The year was further overshadowed by controversy surrounding Gaston's on-court behavior, culminating in multiple unsportsmanlike conduct violations. In May at the Madrid Open, during his second-round match against Ćorić, Gaston intentionally dropped a second ball from his pocket onto the court amid his opponent's smash, aiming to distract and replay the point; this act, his fourth violation of the season, resulted in a $144,000 fine from the ATP, later reduced to $72,000 on appeal—exceeding his tournament earnings and drawing widespread criticism for . Additional incidents, including a contentious retirement on match point against at the Verona Challenger in July while trailing 5-0, 40-0 in the third set, fueled accusations of poor and further tarnished his reputation.

2024: Return to form and second final

Following a challenging 2023 season marked by form struggles, Hugo Gaston showed signs of resurgence in , particularly on his preferred clay surface, where he compiled a 20-12 record across ATP and Challenger levels. He began the year outside the top 100 but steadily climbed through consistent performances, reaching No. 72 in August after his deep run at the Generali Open in . By year's end, Gaston had recovered to No. 76, reflecting improved stability and fewer injury interruptions compared to the prior year. Gaston's clay-court campaign gained momentum in the European spring, highlighted by a quarterfinal appearance at the ATP 250 in , where he defeated Pedro Cachin 6-4, 6-3 before falling to Tomas Martin Etcheverry. This effort contributed to his entry into the top 90 by late May. At the , he exited in the first round to 15th seed in four sets (3-6, 6-3, 6-4, 6-4), but the match showcased his competitive edge on home clay against a strong opponent. His Grand Slam results improved marginally from 2023's winless slate, with a second-round appearance at the Australian Open as a , where he beat 6-4, 3-1 (ret.) before losing to 12th seed 6-0, 6-1, 6-4. First-round defeats followed at Wimbledon (to Alexandre Muller 6-3, 6-4, 6-4) and the US Open (to Facundo Diaz Acosta 6-1, 6-4, 6-2). The pinnacle of Gaston's 2024 season came at the Generali Open in , an ATP 250 clay event, where he reached his second career final. Seeded outside the top 32, he opened with a straight-sets victory over Norbert Gombos (6-1, 7-5), followed by a three-set win against (6-4, 6-7(5), 6-4) in the second round.

In a year-end reflection, he noted satisfaction with climbing from No. 115 to No. 75, attributing the progress to a focused, injury-managed schedule that allowed for better preparation on his favored surface.

2025: Challenger success and top 100 return

Gaston began the 2025 season outside the top 100 but focused on rebuilding through Challenger-level play, culminating in a significant title win that propelled his ranking back into three figures. In September, he captured his fifth career Challenger title at the Open de Rennes, defeating former world No. 3 Stan Wawrinka in the final, 6–4, 6–4, after 1 hour and 26 minutes of play.

At the Open in early , he advanced to the second round as a wildcard, defeating qualifier Terence Atmane 6–4, 6–1 in the opening round before retiring injured against in the next match, down 4–6, 0–6, 0–0 due to an issue. Throughout the year, he qualified for or received entry into multiple ATP 250 and 500 events, posting consistent but unspectacular showings that contributed to his overall ATP-level record of 8 wins and 17 losses. Gaston's Grand Slam campaign reflected his transitional form, with direct entry or successful qualifying at three of the four majors. He reached the second round at the Australian Open and , falling in straight sets to higher seeds in both, while exiting in the first round at Wimbledon and the US Open. These appearances, combined with the and Brest triumphs, facilitated his return to the top 100 on October 13, peaking at No. 96 in October and holding No. 96 as of November 2025, providing momentum for year-end tournaments and a foundation for 2026.

Playing style

Strengths and shot selection

Hugo Gaston plays left-handed with a two-handed , which provides him with solid stability and depth from the baseline, though he occasionally employs a one-handed variation to introduce unpredictability and slice angles into his shot selection. This versatility allows him to disrupt opponents' expectations, particularly by transitioning from rallies to low, skidding slices that force awkward responses. Gaston's primary strengths lie in his finesse-oriented game, highlighted by his exceptional proficiency with drop shots, which he executes with remarkable touch and disguise on both wings. These shots, often delivered short and with heavy backspin, compel opponents to rush forward, creating opportunities for passing shots or net play; he integrates them tactically to break the rhythm of baseline exchanges, winning points through precision rather than outright power. Complementing this, his volleying is sharp and instinctive, enabling confident net approaches after deep approach shots, where he uses quick hands to finish points with angled volleys or overheads. Gaston also favors slice backhands to vary pace and height, pulling rivals wide and opening the court for his stronger drives, which generate aggressive, flat-trajectory balls ideal for dictating play on slower surfaces. His shot selection emphasizes tactical variety over consistent aggression, drawing comparisons to the artistry of veteran French players like , who similarly prioritize angles, touch, and all-court involvement to outmaneuver taller, power-based opponents. By exploiting his lefty serving angles and mixing slices with occasional forehand firepower, Gaston constructs points methodically, often luring foes into the forecourt before capitalizing with precise lobs or drives. Recent Challenger successes in 2025 have further honed his tactical variety on hard courts.

Surface preferences and adaptations

Hugo Gaston is recognized as a specialist, deriving significant advantages from his left-handed game, which includes heavy and tactical variety suited to slower surfaces. His affinity for clay is evident in his career statistics across all levels, where he has compiled a 59.6% win rate (137 wins, 93 losses), outperforming his records on other surfaces. This preference aligns with his upbringing in , where clay dominates the landscape, allowing him to leverage endurance and defensive skills in extended rallies. At the in Roland Garros, Gaston's home major, he has achieved a 46.2% win rate (6 wins, 7 losses) since his debut in , highlighted by a career-best fourth-round appearance in as a wildcard entrant. This breakthrough underscored his comfort on the slow, high-bouncing red clay, where he upset higher-ranked opponents including and before falling to then-world No. 3 . On the specifically, his clay win percentage stands at 44.2% (23-29), reflecting consistent quarterfinal or better runs at events like the and Lyon Open, though without a title. Gaston's challenges intensify on faster surfaces like grass and hard courts, where his serve—limited by his 5'8" (173 cm) frame—lacks the pace and kick to hold serve effectively against aggressive returners, resulting in vulnerability during short points. On grass, he holds a 44.4% career win rate across all levels (8-10), with limited exposure including early exits at Wimbledon in 2022 and 2023. Hard courts present similar hurdles, yielding a 49.5% win rate overall (55-56), but dropping to 34.9% (22-41) at ATP level, often due to struggles with low-bouncing balls disrupting his rhythm. To address these gaps, Gaston has demonstrated progressive adaptations, particularly in movement and shot adjustment on hard courts following his 2022 career-high ranking of No. 58. His indoor hard court results improved notably in late 2021, with deep runs at events like the , signaling enhanced footwork and serve placement under coach . This versatility has evolved through targeted training, enabling better transitions from defense to offense on quicker surfaces, though clay remains his primary domain. Overall, his surface win rates illustrate this progression as of November 2025:
SurfaceAll Levels Wins-Losses (Win %)ATP Tour Wins-Losses (Win %)

Hard55-56 (49.5%)22-41 (34.9%)

These figures highlight Gaston's ongoing efforts to broaden his game beyond clay while capitalizing on his natural strengths there.
