Alexander Bublik was born on June 17, 1997, in Gatchina, Russia, to parents Stanislav and Natalia Bublik. From the age of two, Bublik started playing tennis, and his father, Stanislav, was his coach throughout his childhood.
At the junior level, Bublik played under the Russian flag and showcased his potential by reaching a career-high of 19. Bublik also won 11 titles on the ITF Junior circuit before turning pro in 2016. Bublik began the 2016 season as a player representing Russia, and he made his main draw debut at the St Petersburg Open but did not progress past round one.
He then entered the Kremlin Cup and stunned Roberto Bautista Agut in the round of 16 before losing to eventual competition winner Pablo Carreno Busta. Towards the end of the 2016 season, Bublik changed his national representation to Kazakhstan. He has played under this nation’s flag ever since.
2017 was a breakthrough season for Bublik as he made round two at the Australian Open and won his first Challenger-level event, the Morelos Open, in February. The Kazakhstani player also made his Wimbledon debut but was eliminated by Andy Murray in the first round.
However, Bublik ended 2017 strongly, winning the Aptos Open in August and ending the campaign 95th in the ATP Rankings. Still, Bublik couldn’t progress in 2018 and fell out of the Top 200 after failing to make the main draw of any Grand Slam.
He returned to the Top 100 in 2019 by winning three Challenger events and making round two at the Miami Open between February and April. Bublik went on to have a strong second half to the season, making the second round at the Roland Garros, the third round at the US Open, and reaching his first two ATP finals.
The Kazakhstani player made the final at the Newport Open, losing to John Isner, and the Chengdu Open final, but lost against Carreno Busta. Bublik was an established player by 2020 but struggled to kick on again, with a second-round run at the French Open, his best Grand Slam performance of the campaign.
More success came in 2021, with an early season final run at the Antalya Open. Yet, the final against Alex de Minaur ended in heartbreak as Bublik retired in the first set due to injury. He didn’t have to wait long for another final, though, after making the final two at the Singapore Open before losing to Alexei Popyrin.
Bublik started to show greater consistency throughout 2021. In this season, he made two ATP Masters 1000 quarter-finals in Miami and Madrid. In addition, he made it to the third round at Wimbledon and broke into the ATP Top 40. After a relatively slow start to 2022, Bublik improved rapidly from February and won his first-ever ATP title.
At the Open Sud de France, Bublik defeated Alexander Zverev in the final. Two more finals followed in 2022 in Newport and Metz, although Bublik couldn’t repeat his previous triumph and lost both finals.
In 2023, Bublik struggled to get past the early rounds at the Australian Open, Roland Garros, and several ATP Masters 1000 events. But, an upturn in form for grass season saw the Kazakhstani player win his first-ever ATP 500 competition at the Halle Open, where he beat Arthur Fils in straight sets.
A fourth-round run at Wimbledon followed before Bublik finished the season with another ATP title to his name - the European Open. Bublik had a similar form early in 2024. He failed to progress past the first round at the Australian Open before reaching two ATP finals.
In February, Bublik won his second Open Sud de France title after defeating Borna Coric in the final before making the final at the Dubai Tennis Championships. However, the Kazakhstani player lost here against Ugo Humbert.
