David Ferrer will join Spanish compatriot Rafael Nadal in the year-end World Tour Finals after qualifying into the field for a fourth consecutive year, the ATP announced on Monday.

He becomes the fourth into the field at London’s O2 Arena after Nadal, Novak Djokovic and Andy Murray, who is unlikely to play after undergoing back surgery a fortnight ago.

“I’m very happy to qualify for the Barclays ATP World Tour Finals for the fifth time,” said Ferrer.

“At the beginning of the year it’s always a goal to make it to London and if you finish in the top eight then you know that you’ve had a good season.”

Over the next four weeks, four more singles titles and five places in doubles will be decided for London. Next in the queue for qualification should be Juan Del Potro.

Others in contention include Tomas Berdych, Federer and Stanislas Wawrinka, the provisional fifth through eighth-place players. Also in the running: Richard Gasquet, Milos Raonic, and Jo-Wilffied Tsonga.
