Sixth seeds Ellen Perez and Nicole Melichar-Martinez will vie for a berth in the WTA Finals decider for the second year running after winning their final group-stage match at the season-ending championships.
The Australian-American duo eased past top seeds Lyudmyla Kichenok and Jelena Ostapenko 6-1 6-3 in Riyadh for a second win from three clashes to finish second in the Green Group.
"We made a lot of first serves and were able to jam them up pretty well," Perez told wtatennis.com. "We kept really positive and energetic, and that was the goal for the match - just to stay upbeat."
Katerina Siniakova and Taylor Townsend remained unbeaten on top of the group after they ended third seeds Hsieh Su-wei and Elise Mertens' campaign, which ensured Perez and Melichar-Martinez's progression to the knockout stage.
