British No.1 Johanna Konta has failed to qualify for the WTA Finals after she pulled out of next week's Kremlin Cup with a left foot injury.
The World No. 10 looked a near certainty to claim the final eighth spot for the showpiece event in Singapore later this month until Caroline Garcia's remarkable run.
The Frenchwoman has taken advantage of Konta's recent poor form with back-to-back titles at the Wuhan and China Opens, two of the biggest events on the WTA Tour.
Konta could still have overtaken Garcia by reaching the final in Moscow but has not recovered from the foot problem that forced her to pull out of this week's tournament in Hong Kong.
It is the second year in a row that the 26-year-old has narrowly missed out on reaching the WTA Finals.
Twelve months ago, she travelled to Singapore and took part in all the pretournament publicity only for Svetlana Kuznetsova to usurp her at the final moment by winning the Kremlin Cup.
It is still possible that Konta, who has lost her last five matches, will travel to Singapore as first alternate, which would see her take the spot of any player forced to pull out.
