Elena Rybakina Withdraws from WTA Finals Due to Viral Illness

World number one Elena Rybakina withdrew from the season-ending WTA Finals, citing a viral illness that left her physically unable to compete. The defending champion announced on Saturday that she was not ready to continue playing, leading organizers to replace her in the draw with first alternate Marta Kostyuk ahead of the tournament at Indian Wells.

Rybakina concluded her 2026 campaign with a 54-14 win-loss record and four titles, including major victories at the Australian Open and the U.S. Open. Her triumph in New York propelled her to the top of the WTA rankings for the first time in her career. Because she had already secured the year-end number one ranking, her withdrawal does not affect her standing at the summit of women's tennis.

Competitors and tennis organizations offered mixed reactions to the news. World number two Aryna Sabalenka admitted she was shocked by the development but voiced support for her rival. «I was shocked, but not surprised. Still, she had an amazing season. She had already secured the No. 1 spot, so I think it was the right decision to focus on her health, get some good rest and start the new season with renewed energy,» Sabalenka said.

The Professional Tennis Players Association (PTPA) seized upon the withdrawal to criticize the grueling professional tennis calendar. In a social media statement, the association noted that Rybakina finished the year with two Grand Slam titles and four overall victories, yet «her body had nothing left to give» by November.

«Players shouldn’t reach the biggest event of the year running on empty. The PTPA continues to push for a season that leaves players healthy enough to finish it,» the organization declared. The PTPA argued that athletes face excessive physical and mental demands throughout the year.

The WTA Tour has previously maintained that player welfare remains a top priority and that it takes athletes' feedback regarding the calendar seriously. However, discussions surrounding player workload extend beyond the women's tour, echoing similar complaints raised within the men's ATP circuit regarding brief off-seasons and demanding competition schedules.
