Iga Swiatek and Coco Gauff enjoyed winning starts to their WTA Finals campaigns in Riyadh on Sunday, albeit in contrasting fashion.

Swiatek began her title defense with an comeback, rallying back from a set and a double-break down to overcome eighth-seeded Barbora Krejcikova 4-6, 7-5, 6-2 in 2 hours, 33 minutes.

The win was crucial for the Polish second seed to keep her hopes of wrestling back the No. 1 ranking from Aryna Sabalenka alive.
