World number one Elena Rybakina has stepped aside from the WTA Finals in Indian Wells, citing a viral illness that left her body not physically ready to compete. The 27-year-old Kazakh announced her decision on Saturday, the eve of the season-ending tournament, effectively ending her bid to defend the title she won in 2025. According to Sportstar, Ukrainian player Marta Kostyuk will take Rybakina's place in the eight-player field, with an opening match against Linda Noskova scheduled for Sunday.
Tournament director Garbine Muguruza addressed the news in a statement reported by Asharq Al-Awsat, describing the withdrawal as a blow but noting that the remaining field remains strong. Muguruza suggested that Rybakina requires rest to manage the physical demands of a long season. The Kazakh player had been aiming to join American great Serena Williams as the first player since 2014 to claim the WTA Finals title in consecutive years.
Rybakina’s 2026 campaign was her most successful to date, as reported by BBC Sport via the Nile Post. She captured the Australian Open and US Open titles, along with wins in Stuttgart and Ningbo. She also reached the finals at Indian Wells and Toronto. Her dominance was highlighted by tour-leading serve statistics, including 438 aces and 1,775 winners. She ended the season with a record of 54 wins from 68 matches, including 17 wins in 19 Grand Slam tournaments.
The Kazakh clinched the year-end top ranking during her October appearance in Tokyo, displacing Aryna Sabalenka from the number one spot after a 99-week hold. This shift followed Rybakina's US Open final win over the Belarusian six weeks prior. Rybakina has claimed six of her 15 career titles since October last year, a period marked by sustained success that included her maiden Grand Slam triumph at Wimbledon in 2022. Her withdrawal leaves the tournament without its top seed, though the remaining players are expected to provide a high level of competition.
