Daria Kasatkina: Australia’s New No. 1
Switching the country you represent in professional tennis is a genuinely significant decision β one that carries political weight, personal history, and years of paperwork alongside the sporting implications. Daria Kasatkina made that switch in 2025, moving from Russia to Australia, and by 2026 had become her adopted country’s top-ranked woman on tour.
A career built from Tolyatti to the world’s top 10
Kasatkina was born on 7 May 1997 in Tolyatti, Russia, and turned professional in 2014. She built a genuinely substantial career representing Russia for over a decade, reaching a career-high singles ranking of world No. 8 in October 2022 and winning eight WTA Tour singles titles across her career, plus a doubles title. Her best Grand Slam results came at the 2022 French Open, where she reached the semifinals, and the 2018 Wimbledon Championships, where she made the quarterfinals β genuine top-tier results against the sport’s best players.
A distinctive game built on variety
Kasatkina has built her reputation on tactical intelligence and shot variety rather than pure power β a right-hander with a two-handed backhand whose game relies on changes of pace, drop shots, and court craft to unsettle opponents, a genuinely distinctive style in an era of the WTA Tour often dominated by baseline power.
Switching to Australia
In March 2025, Kasatkina announced she would represent Australia at all future tennis events, having been granted permanent residency in the country. She acquired full Australian citizenship in early 2026, becoming, by that point, the nation’s leading woman on the WTA Tour. Speaking ahead of the 2026 Australian Open β her first as an official Australian competing in front of a home crowd β she described the moment as special: “Really happy to be an official Australian now and just to participate in Australian Open and in front of the great crowd here,” adding that she’d need to “manage my nerves” in a situation she’d never experienced before.
A difficult stretch, and a mental health break
Kasatkina’s 2025 season included genuine struggles alongside its highlights β her best results that year were fourth-round runs at both the Australian Open and French Open, but she made the decision to end her season early after the Beijing tournament to take a mental health break, a candid and increasingly common choice among tour professionals prioritising wellbeing over a full competitive schedule. She still finished the season ranked inside the world’s top 40 for a fifth consecutive year, a genuine marker of sustained consistency even through a difficult stretch.
2026: a title, and continued rebuilding
Kasatkina began 2026 aiming to rebuild toward her career-best ranking, telling reporters her level of tennis had returned to a better place than much of the previous season, backed by a straight-sets win over former world No. 3 Maria Sakkari at the Adelaide International. She added a WTA 125 title at La Bisbal d’Emporda during the year, continuing to compete across both the main tour and its developmental tier as she works to climb back toward the top of the rankings.
Where her career stands
Daria Kasatkina’s story now includes both a genuinely accomplished decade of Russian-flag tennis β a top-10 ranking, a Grand Slam semifinal, eight tour titles β and a new chapter representing Australia, a country she’s embraced as home and that’s embraced her in return as its leading female player. With her level trending upward again in 2026 and a home Australian Open crowd now behind her, there’s real reason to think her best tennis isn’t entirely behind her.
