Caroline Wozniacki lost the opening match of her WTA Finals defence with a 6-2 6-4 upset to seventh seed Karolina Pliskova.

The Czech needed just 32 minutes to wrap up the first set, coming from a game two break points down she reeled off five games in succession on her way to closing it out 6-2.

Wozniacki survived a tight service game, saving two match points, to reduce her second-set deficit to 5-4 but could not prevent Pliskova serving for victory. ‘They are always tough matches against Caroline,’ she said in her post-match interview.
