Great Britain's stay at the Billie Jean King Cup Finals lasted only one match as they fell to Czechia in the quarter-finals in Shenzhen.

Anne Keothavong's side were bidding to reach the last four for the fourth time in five years but were considerable underdogs and defeats for Sonay Kartal and Katie Boulter sealed their fate.

Led by Wimbledon champion Linda Noskova, the whole Czech team is ranked higher than any of Britain's players, and it was Noskova who sealed victory with a 6-2 7-6 (7-3) win over Boulter.

That followed a lengthy struggle between Marie Bouzkova and Kartal lasting a minute short of three hours, which the Czech eventually took 7-6 (7-2) 4-6 6-4.

Keothavong said: "For both these players, it required their absolute best and a bit of luck for the result to go our way. I can't fault their efforts. I think the Czechs are the strongest team here. I'd be surprised if they don't go on to win this competition."

It was a fine effort from Kartal, who was playing her first match in six months after suffering a stress fracture in her back in Indian Wells in March and she will now hope to finish the season strongly.

The Czechs will bid for their seventh title in the competition since 2011 while Britain's hopes of lifting the trophy for the first time are over for another year.
