Alexander Bublik is one of the most unpredictable and entertaining players in tennis, and in January 2026 he became the first man from Kazakhstan to break into the ATP top 10. The Hong Kong title that put him there, his ninth, capped a resurgence that began in 2025, when he won four titles on three surfaces. Armed with one of the biggest serves on tour, a taste for underarm serves and trick shots, and a fearless, high-risk style, he is equal parts showman and genuine threat.
The rest of 2026 has been steadier than spectacular: a Kitzbühel final, semifinals in Rotterdam, Geneva and Stuttgart, and fourth-round runs in Melbourne and at Wimbledon. He has slipped to No. 21 in the rankings, and made his Laver Cup debut for Team World in London in September. “I signed certain papers [with Andre] to never underarm serve here, not to smile after points,” he joked before the event, according to the ATP Tour.

Game overview
Bublik’s game starts with a serve that ranks among the most prolific on tour and extends into a repertoire few others attempt: underarm serves, drop shots and audacious shotmaking. The flair can read as casual, but behind it is a player who can string together wins over elite opponents, as his 2025 win over world No. 1 Jannik Sinner on the way to the Halle title showed.
Playing style and strengths
Serve. A huge, varied delivery that produces free points and dictates his service games.
Creativity and risk. Trick shots and unpredictability that unsettle opponents and entertain crowds.
Range across surfaces. In 2025 he won titles on clay, grass and hard courts in the same season, becoming only the third player this decade to do so after Novak Djokovic and Carlos Alcaraz, according to the Laver Cup.
Pressure points and vulnerabilities
- Consistency: the high-risk style produces sharp swings in form
- Holding his ranking: from No. 10 in January to No. 21 by September
- Return games and longer rallies against the most disciplined opponents
- Building on a single Grand Slam quarterfinal toward a first semifinal
Career milestones
- 2022: First ATP title in Montpellier, beating then-No. 3 Alexander Zverev in the final
- 2025: Titles in Halle, Gstaad, Kitzbühel and Hangzhou, and a maiden Grand Slam quarterfinal at Roland Garros
- 2026: Hong Kong title and a top-10 debut, a first for a Kazakhstani man
- 2026: Laver Cup debut for Team World
Grand Slam record in context
Bublik’s major record long lagged his talent until the 2025 Roland Garros quarterfinal. He followed it with a fourth round at the US Open that year, and in 2026 reached the fourth round in Melbourne, where he beat Tomás Martín Etcheverry before losing to Alex de Minaur, and again at Wimbledon. He went out in the third round of the US Open. Converting that consistency into a first major semifinal is the next step.
Grand Slam best results
- Australian Open: Fourth round (2026)
- Roland Garros: Quarterfinal (2025)
- Wimbledon: Fourth round (2026)
- US Open: Fourth round (2025)
What to watch next
- The indoor swing: faster courts that suit his serve, and a chance to climb back toward the top 15.
- A deeper Slam run: building on his first quarterfinal.
