A pumped up Dominika Cibulkova kept her hopes of qualifying for the WTA Finals last four alive and dumped Simona Halep out with a straight-sets victory in Singapore on Thursday.

Cibulkova had to win her final Red Group match in two sets in order to have any chance of making it through and a 6-3 7-6 (7-5) kept the tournament debutant in the hunt.

Halep, playing with heavy strapping on her left knee, would have advanced with a win in her last round-robin match, but the third seed's season was ended by the impressive Cibulkova.
