Elena Rybakina Withdraws from WTA Finals in Indian Wells Due to Illness

World No. 1 Elena Rybakina has withdrawn from the 2026 WTA Finals in Indian Wells, California, citing a viral illness. The defending champion announced her departure from the tournament, explaining that her body is not physically ready to compete after a demanding season.

Rybakina entered the event as the top seed and the reigning champion following her undefeated run at the 2025 tournament in Riyadh. Her 2026 campaign included winning her third Grand Slam at the US Open, securing the year-end No. 1 singles ranking, and capturing four titles overall with a 54-14 match record. She expressed disappointment over missing the competition and stated her intention to rest and recover at home in preparation for the 2027 season.

With Rybakina's withdrawal, Marta Kostyuk steps into the tournament as an alternate. Kostyuk, who is coming off a career-best season that featured her first WTA 1000 title in Madrid and Grand Slam semi-final appearances at Roland-Garros and Wimbledon, joins Group 1. She is scheduled to open against Linda Noskova, alongside round-robin matches against Coco Guggling and Jessica Pegula.

The absence of the world No. 1 has altered expectations for the field. Former Wimbledon champion Marion Bartoli pointed out the physical toll that a long season and travel from Asia can take on players' immune systems. Following Rybakina's exit, Bartoli named Aryna Sabalenka as her favorite to capture the title, highlighting Sabalenka's strong history on American hard courts.

Sabalenka enters the tournament as the highest-ranked remaining player and is looking to secure her first title at the year-end event after finishing as runner-up in previous editions. Her opening round-robin matches place her in a group with Karolina Muchova, Mirra Andreeva, and Elina Svitolina.

Meanwhile, other top competitors like Iga Swiatek had already ended their seasons early to rest for 2027. Swiatek finished ninth in the race and could have potentially taken the alternate spot that went to Kostyuk, but chose to focus on recovery after a challenging physical and mental year.
