Alexander Donski

Alexander Donski (; born 1 August 1998) is a Bulgarian professional tennis player active on both the ITF Men's World Tennis Tour and the ATP Challenger Tour.

Donski holds the third highest-ever ATP doubles ranking by a Bulgarian, achieving a career-high of world No. 193 on 17 March 2025. Only Grigor Dimitrov and Orlin Stanoytchev have achieved a higher ATP doubles ranking for a Bulgarian player, reaching No. 66 and No. 156 respectively.

Donski has won 19 ITF Men's World Tennis Tour titles in doubles and is an active member of the Bulgarian Davis Cup Team.

YouTube Channel

In late 2016, Donski began a YouTube channel called ''Operation Liftoff'' that documented his progress at Futures tournaments on the ITF Pro Circuit as well as showcased some of the challenges and routines of a professional tennis player's life on tour.

The channel was made in close collaboration with his cousin, Lazar Dokov, who traveled with and competed alongside him in Southeastern Europe until October 2017.

As of January 2025, the channel has 40 videos, over 6,000 subscribers, and more than 800,000 views in total.

ITF Junior Career

Donski reached a career-high ITF junior ranking of No. 92 on 24 October 2016.

The highlights of his activity in singles on the ITF Junior Tour include the following:

* Reaching the final round of qualifying at the 2016 Junior US Open (''3-6, 6-3, 3-6 vs Patrick Kypson'')
* Two finals at Grade 2 events in Bulgaria and the Netherlands (''5-7, 3-6 vs Sebastian Baez)'' respectively
* One Grade 5 title in Bulgaria

In doubles he won three titles including a Grade 1 event in Morocco, a Grade 4 event in the United States, a Grade 5 event in the Bahamas, and made one further final at a Grade 4 event in Greece.

Overall, in international junior competition, Donski compiled a cumulative win/loss record of 68-47 in singles and 33-40 in doubles. Donski represented Canada in international competition until June 2016, after which he began representing Bulgaria, citing heritage and favorable player development opportunities.

Professional career

Donski officially turned pro in 2017, however, as early as 2014, he played a limited number of Futures tournaments on the ITF Pro Circuit to gain experience alongside his main activity on the ITF Junior Tour. As an amateur, he qualified twice for the main draw of a Futures tournament, once in the Dominican Republic in late 2015 and a second time in Greece a year later.

2017: First ATP points

In 2017, Donski acquired his first two ATP singles points that elevated him to the year-end ranking of No. 1575. Both points came in the summer at two $15K events held in Istanbul, for which he successfully qualified. As a qualifier in the main draw, he defeated a Turkish lucky loser to win the first ATP point, and then in the next event defeated a fellow qualifier, also from Turkiye, to win the second. Donski positioned himself to play for ATP points on 6 other occasions that same year, however he was unable to secure further points.

Some of the more notable opposition he faced in 2017 who barred him from acquiring additional ATP points included Hubert Hurkacz, Botic van de Zandschulp, and Tallon Griekspoor.

Most of his first season as a professional player was well documented on his YouTube channel.

2018: ATP 250 wildcard, uphill battles

Donski made his ATP main draw debut at the 2018 Diema Xtra Sofia Open, receiving a wildcard into both the singles and doubles tournament after winning the Bulgarian Men's Indoor National Championships, defeating the then Bulgarian singles No.3, Aleksandar Lazov (ATP No. 400) 3-6, 6-3, 6-4 in the final. Donski was defeated in straight sets by Martin Klizan in the first round of the singles draw before also falling in the first round of the doubles draw.

In 2018, Donski only saw limited progress on the singles front. Despite competing in the main draw of Futures events another 6 times, he accumulated only 3 ATP points that year. He was unable to advance further than the second round of the main draw of any given singles event. In doubles, he fared better and reached his first final partnering Vasil Kirkov in Sozopol and made two other semifinal runs. He finished the year ranked No. 1431 in singles and No.1061 in doubles.

2019: First Futures Titles in Singles and Doubles

In 2019, Donski made significant progress on the ITF Men's World Tennis Tour in both singles and doubles. In singles, he captured his first Futures title in October at an M15 event in Pretoria, defeating Arthur Cazaux 7-6(3), 6-7(5), 7-6(6) in the final. Prior to that victory, he managed to reach three other finals earlier in the year at the M15 events in Sozopol, Telavi, and Johannesburg.

In doubles, Donski reached five finals and converted on two occasions. He won his first title at an M15 in Telavi and then another in Pretoria later in the year, where he also won his first singles title. These strong showings in both singles and doubles afforded him the year-end ATP rankings of No.585 and No.429 respectively.

2020: Obstacles - pandemic and ITF adjustments

In 2020, along with many other players, Donski struggled to adapt to the challenges of traveling and competing at professional events under the changing realities and restrictions of the COVID-19 pandemic. He dedicated a video on ''Operation Liftoff'' to describing his experience of the disruptions that emerged.

In singles, out of a truncated schedule of just 10 events that year, including a Davis Cup match in Costa Rica, Donski won only 3 matches in total and never managed to pass the second round at any event. The most competitive singles match he played that year came in November at the second round of an M15 event in Antalya, where he clashed with recent ITF Junior No.1, Holger Rune. Rune defeated Donski 5-7, 6-3, 6-3.

In doubles, Donski also found little success, making just a single semifinal appearance in October at an M15 event in Sharm El Sheikh.

Despite these setbacks, his year-end ATP ranking for singles did not change substantially (ended No.596), as two temporary special provisions across the tour were in place at the time. One was a freeze of ATP points won in 2019 to account for disruptions in the regular event calendar by the pandemic, while the other was related to ongoing experimental structural changes in the ranking system by the ITF. Donski's year-end doubles ranking, however, did drop by more than 240 spots to No.671 because of the timing of the acquisition of previous points.

2021: Rebuilding momentum

Donski did not win any singles titles in 2021, however he did regain some of the form lost in the uncertainty of the previous year. He reached at least the quarterfinals of four separate events and advanced to the semifinals of two of those events (both in the M15 category), one in Monastir and the other in Sozopol.

In late September 2021, Donski scored his first singles win at the ATP level at the 2021 Sofia Open, where he received another wild card for the singles qualifying draw. He pulled an upset win over eighth seed Jurij Rodionov 2-6, 6-1, 7-6(4) before losing in the final round to the Italian veteran, Andreas Seppi. He also played in the doubles competition at his home ATP tournament with Dimitar Kuzmanov, but the Bulgarian duo lost in a third set tiebreaker to eventual champions Jonny O'Mara and Ken Skupski. Cumulatively, however, these results could not prevent his singles ranking from dipping to ATP No. 659 by end of the year.

The Bulgarian fared better on the doubles scene and resumed building up his ranking during the 2021 season. Donski seized three more ITF titles, securing a victory at the M15 event in Sozopol with Billy Harris and following it up with triumphs at the M25 events in Saint-Dizier and Villers-lès-Nancy with Petros Tsitsipas. He also made it to the final of an M25 event in Říčany partnering Colin Sinclair, but the pair came up short. Donski finished the year ranked No. 505 in doubles.

2022: Second ITF singles title, strong season in doubles

In late January 2022, Donski ended a two-year stretch of failing to reach the final of an ITF singles event, by winning four consecutive matches in the main draw of an M15 event in Monastir. He was only defeated in the championship round in three sets 0-6, 6-3, 5-7 by Laurent Lokoli of France. One month and a half later, however, Donski would return to Monastir to compete at another M15 event and this time would indeed emerge victorious, picking up only his second ever ITF Men’s World Tennis Tour singles title. He defeated another Frenchman, Terence Atmane, in the final round 6-2, 5-7, 6-3.

Despite Donski’s surging form in singles in the beginning of the year, this momentum would not carry through the spring or the summer. It was not until October 2022 when he would once again string together multiple consecutive matches. He reached a further three semifinals in the M15 category (twice in Sozopol and once in Monastir) before the year’s end. Ultimately, 2022 was actually a rather stagnant year in terms of singles rankings progress for Donski. His results only allowed him to improve his ranking to ATP No.628, only 31 spots higher than the year before.

In contrast to his performance in singles, Donski continued to push the front in doubles and reached new heights. In 2022, Donski reached six finals and, of those finals, captured four titles (three M15 events, one M25). Interestingly enough, Donski accomplished this with six different partners (Théo Arribagé, Zvonimir Babić, David Pichler, Karl Friberg, Vladyslav Orlov, and Tim Sandkaulen) reinforcing his claim as a highly adaptable player in the game of doubles.

This versatility also manifested itself in a strong 6-3, 7-6(6) victory over the South African team of Raven Klaasen (former ATP no.7 in doubles) and Lleyton Cronje Davis Cup competition in September back in Bulgaria. In addition, Donski made good use of another wildcard at the ATP 250 event in Sofia by defeating the team of Fabrice Martin and Aisam Qureshi (a former top 10 doubles player) 4-6, 6-3, 10-8 alongside his countryman, Alexandar Lazarov. Donski and Lazarov were defeated in the next round by the top seeded team of Simone Bolelli and Fabio Fognini.

This success catapulted him to a then career-high ATP doubles ranking of No.248, which he achieved in October 2022. His final year-end ranking, however, was slightly lower at No.259.

2023: Doubles takes priority

Donski maintained solid form in doubles from the previous season. He won three M15 titles with three different partners, all on hard courts in Monastir.

He also made four other finals at M15 events (Antalya, Štore, Celje, Monastir), and regularly penetrated as deep as the semifinals of many of the other tournaments that he played in.

The 2023 season, however, was not a successful one in singles for Donski. Out of a mix of 23 tournaments, including 3 ATP Challenger events and another wildcard at the ATP 250 event in Sofia, he only made it to the semifinals of one Futures event, an M15 event in Monastir in late October. Most of his other defeats came either in qualifying rounds or the early rounds of main draws.

Donski ended the year ranked ATP No. 935 in singles and No. 315 in doubles.

2024: Career-high doubles ranking, ATP Challenger Tour inroads

In 2024, Donski accelerated his trajectory as a doubles specialist on the ATP tour and vastly outdid any of his performances in previous years by capturing seven ITF titles across tournaments held in Portugal, Tunisia, and Spain. Four of Donski’s wins came in the M25 category, while the other three came in the M15 category. He also started making inroads at the Challenger level, reaching the semifinal round of a $100K event in Luedenscheid, as well as a final and a semifinal at $50K events in Segovia and Dobrich, respectively.

Of the nine doubles finals that Donski reached in 2024, six of them (four M25s, an M15, and the Challenger 50) came in partnership with the Portuguese player, Tiago Pereira. This success propelled Donski to a career-high ATP doubles ranking of No. 217 on the 26 August 2025, the third highest-ever doubles ranking a Bulgarian player has ever achieved.

In singles, despite obstacles posed by his lower ranking earlier in the year, Donski found some surprising success at three consecutive ATP Challenger 50 events that took place over the summer.
In both Open de Pozoblanco and Dobrich Challenger, Donski passed the qualifying draw and made it to the second round of the main draw. In Pozoblanco, he handily defeated Ulises Blanch in the first round before narrowly falling to second seed and former top 100 player, Egor Gerasimov, 6-4, 3-6, 4-6 after having led 3-0 with a double break in the final set. In the third Challenger 50 event that he played (a second tournament in Dobrich), he received a wildcard into the main draw that he made good use of by reaching the quarterfinals.

Donski finished 2024 with a year-end ATP singles ranking of No. 746.

2025: Maiden Challenger title, top 200 debut in doubles

In his second tournament of the year, Donski reached the final of an M25 doubles event in Luxembourg partnering Bruno Pujol Navarro. Shortly thereafter, in early February, he was summoned by the Bulgarian Davis Cup Team to play doubles in a World Group I tie against Romania where he and his partner Pyotr Nesterov delivered a critical 6-3, 6-3 victory over Victor Vlad Cornea and Gabi Adrian Boitan.

Following his maiden title at the 2025 Rwanda Challenger II, where he partnered India’s Siddhant Banthia, Donski reached the top 200 in doubles on 17 March 2025.
