"Unfortunately, I have to withdraw from today's match due to gastrointestinal issues," Muchova said in a statement. "It's not how I wanted to end my season, but there's a lot to be proud of and I'm already looking forward to next year."

Regardless of the result vs. Shnaider, Andreeva has already secured first place in Group 2 with straight set wins over No. 6 Elina Svitolina and No. 2 Aryna Sabalenka. She'll face No. 5 Jessica Pegula for the first time on the WTA Tour Driven by Mercedes-Benz in the tournament's semifinals on Saturday.

Muchova finishes her 2026 season with a 41-14 record, and was already eliminated from knockout stage contention with losses to Sabalenka and Svitolina. This year, she won titles in Doha and Bad Homburg, and reached the final at Wimbledon.

Andreeva holds a 2-0 lead against Shnaider in the head-to-head, most recently defeating her en route to the title at Adelaide in January.
