Boulter & Burrage secure GB's BJK Cup Finals place

Great Britain's hopes of reaching the Billie Jean King Cup Finals rest on a decisive doubles match against the Netherlands after Katie Boulter was beaten in the singles.

Victory for British number one Boulter would have wrapped up the tie after Sonay Kartal's 6-4 4-6 6-1 win over Eva Vedder.

However, Boulter struggled for consistency in a 6-4 6-3 loss to Suzan Lamens on clay in The Hague.

Boulter will, however, team up with Jodie Burrage to take on Lamens and Demi Schuurs in an attempt to secure Britain's place in September's eight-team finals.

Britain beat Germany 2-1 on Friday, with wins for Boulter and Kartal in the singles, before doubles specialist Olivia Nicholls and Harriet Dart lost in straight sets.

World number 40 Boulter is ranked 30 places higher than Lamens but the Dutchwoman looked more comfortable in sliding and moving around on the clay.

Boulter was always behind in the match, saving break points in the first game before going a double break down as her forehand misfired.

When Boulter connected her power was too much for Lamens, but she could not consistently find her range, despite briefly threatening a comeback after rescuing one of the breaks in the opening set.

The Briton broke first in the second set, a nicely angled backhand forcing the error from Lamens, but she immediately surrendered the break with a wayward service game.

From there, Lamens did not look back. Cheered on by a partisan crowd, she won three games in a row to keep her nation in the tie.

Kartal had earlier put Britain in a fine position with a gritty win over Vedder.

She came back from an early break down in the first set, hitting 11 winners to Vedder's seven as she outmuscled her in the forehand exchanges.

Kartal should have broken world number 265 Vedder in the first game of the second set, missing three break opportunities before rattling through her own service games with ease.

However, she was not helped at 4-3 up when umpire Eva Asderaki-Moore incorrectly overruled an out call on a Vedder forehand.

Had it not been overruled, Kartal would have had a break point. Instead, the point was replayed, Vedder held serve and then broke Kartal in the next game.

Vedder played her best tennis in the final two games of the second set, drawing errors out of Kartal before wrapping up the set with an ace.

The Briton put her frustration aside for the third set, quickly going a break up and putting her heavy forehand to good use to win the final five games in a row.
