Great Britain edge Croatia to reach World Group II play-offs

Johanna Konta and Heather Watson rallied from a set down in the decisive doubles rubber to overcome Ana Konjuh and Darija Jurak 4-6 6-4 6-3.

Earlier, British No.2 Watson had put GB on the cusp of victory with a 6-2 6-4 win over Donna Vekic, but Konta slumped to a surprise 6-4 6-3 defeat to 19-year-old Konjuh to send the tie to a decider.

Konta and Watson then endured the worst possible start to the final match as the Croatians secured a double break to lead 3-0 and, despite some resistance, they eventually lost the first set 6-4.

Australian Open quarter-finalist Konta then caused some consternation by receiving treatment to her left ankle early in the second but she shrugged off the minor problem to help restore parity and force a deciding set.

Konta dropped the opening service game of the third, double-faulting to give the Croatians an early advantage, but the next three games also went against the serve to leave it tied at 2-2 with the tension mounting.

The British duo then finally put daylight between themselves and their opponents to wrap up victory.

Victory in Tallinn means Anne Keothavong's team progress to a further play-off in April, which could see them reach the competition's second tier - World Group II - for the first time in almost a quarter of a century.
