RIYADH: Elena Rybakina stayed unbeaten at the WTA Finals with a 6-4, 6-4 victory over second alternate Ekaterina Alexandrova today after Madison Keys withdrew from their final round robin meeting with illness and Mirra Andreeva was not fit to play.
Rybakina arrived for the clash after victories over Amanda Anisimova and Iga Swiatek but the former Wimbledon champion came under pressure against a fresh Alexandrova, before breaking in the ninth game and then claiming the opening set with a hold.
The Kazakh, who staved off three breakpoints in the first set, cranked up her big serve and heavy hitting early in the second to go 3-1 up and applied the squeeze to close in on another win ahead of the semi-finals.
