Underdog to Champion: The Rise of Aryna Sabalenka
Aryna Sabalenka did not arrive on the tennis scene as a polished junior prodigy destined for greatness. Born on 5 May 1998 in Minsk, Belarus, her introduction to the sport was almost accidental. At the age of six, her father Sergey, a former ice-hockey player, was driving with her when they passed some tennis courts. On impulse he stopped, handed her a racquet, and let her try. She liked it enough to continue. That simple moment set in motion one of the more compelling underdog-to-champion stories in modern women’s tennis.
Unlike many of her peers who were pushed into intensive junior circuits and Grand Slam junior events from an early age, Sabalenka took a slower and less conventional route. Belarus lacked the deep, well-funded national development systems found in countries such as Russia, China or France. She never played junior Grand Slams. Instead, the Belarusian Tennis Federation encouraged her to compete in lower-level professional events while she was still eligible for juniors. Her junior ranking never rose higher than the mid-200s. Coaches openly doubted her. Sabalenka has recalled being told she was “stupid,” that all she could do was overhit the ball, and that she would never reach the top 100. She did not win her first main-draw match on the WTA Tour until she was 19, at Wimbledon in 2017 as a qualifier.
Those early years demanded resilience. Progress came in increments rather than explosive leaps. In 2017 she and Aliaksandra Sasnovich led Belarus to the Fed Cup final despite both ranking outside the top 75, a result that first brought her wider attention. Titles followed in 2018 and 2019, including strong results in China that helped her finish both seasons ranked No. 11. Doubles success arrived faster. Partnering with Elise Mertens, she won the 2019 US Open and the 2021 Australian Open, briefly becoming world No. 1 in the discipline. The partnership also delivered the Sunshine Double in 2019. Yet singles glory remained elusive. Her game was built on raw power — flat, heavy groundstrokes and a big serve — but consistency and emotional control lagged behind.
Tragedy struck in November 2019 when her father Sergey died suddenly from meningitis at the age of 43. The two had shared a dream that she would win Grand Slam titles. The loss left a deep mark. Sabalenka has spoken about feeling the pressure of that unfinished promise, especially as she approached her mid-20s still without a major singles title. Technical issues compounded the emotional weight. In 2022 her serve collapsed into a damaging pattern of double faults that threatened to undermine her entire game. She remained a dangerous opponent capable of beating anyone on a given day, but the highest prizes stayed just out of reach.
The breakthrough finally came in 2023. At the Australian Open she defeated Elena Rybakina in a three-set final to claim her first Grand Slam singles title. Later that year she reached the US Open final, losing to Coco Gauff, and briefly ascended to world No. 1 for the first time. The experience of holding the top ranking, even for a short period, taught her what the position demanded. In 2024 she returned stronger and more complete. She successfully defended the Australian Open title, then captured the US Open by beating Jessica Pegula in the final. Those two majors, combined with consistent results elsewhere, secured her first year-end No. 1 ranking.
Consistency became her hallmark. In 2025 she defended the US Open title, becoming the first woman to win consecutive US Open crowns since Serena Williams more than a decade earlier. She reached the finals of both the Australian Open and the French Open that year as well, finishing runner-up on both occasions. Across the season she remained the player everyone had to beat, winning multiple titles and holding the No. 1 ranking throughout. By 2026 she had established a sustained grip on the top of the game. She reached a fourth consecutive Australian Open final (losing to Rybakina in a rematch of their 2023 final), then completed the Sunshine Double by winning Indian Wells and Miami back-to-back. As of mid-August 2026 she continued to sit at No. 1, having spent the vast majority of the previous 20 months in the position.
The technical and mental evolution behind these results was significant. Long-term work with coach Anton Dubrov provided stability. Specialist help, including time with serve coach Gavin MacMillan, helped restore reliability to her delivery. She learned to channel the intensity that once produced visible frustration into sustained focus. On court she remained aggressive and loud, still known for the powerful groundstrokes and competitive fire that earned her the nickname “The Tiger,” a reference to the tiger tattoo on her arm. Off court she gradually revealed a warmer, more humorous personality through social media, sharing unfiltered moments rather than carefully managed content. That openness helped close the gap between the fierce competitor fans saw and the person she actually is, building a more loyal following in the process.
Sabalenka’s career numbers now reflect the scale of her achievement: four Grand Slam singles titles (Australian Open in 2023 and 2024, US Open in 2024 and 2025), more than 20 tour-level singles titles, and prize money that places her among the highest earners in the sport’s history. She has reached eight major singles finals and maintained deep runs at nearly every Grand Slam she has played in recent years. Hard courts have been her strongest surface, but she has also pushed deep into the clay and grass seasons, proving she is no longer a one-surface threat.
What makes the story compelling is not simply the list of titles. It is the distance travelled. Many players who dominate junior tennis struggle to translate that success to the professional level. Sabalenka faced the opposite problem: limited early pedigree, open scepticism from coaches, a modest national support system, personal loss, and technical crises that could have ended her momentum. She answered each setback by refining her game and hardening her mindset. The result is a player who combines enormous power with improved reliability and the mental toughness required to stay at No. 1 for extended periods.
As she continues to compete at the highest level into her late 20s, Sabalenka stands as proof that the traditional path is not the only route to the top. From a chance encounter with tennis courts in Minsk to four major titles and sustained dominance as world No. 1, her rise remains one of the clearest underdog-to-champion narratives in contemporary tennis. The power was always there. The belief, the consistency, and the championships had to be earned the hard way.
