Emma Raducanu knocked out of Korea Open after three-set defeat to Barbora Krejcikova

Emma Raducanu has been knocked out of the Korea Open after suffering a three-sets defeat to former Wimbledon champion Barbora Krejcikova.

Krejcikova was on the brink of defeat but staged a remarkable turnaround to beat the British star 4-6 7-6 (12-10) 6-1.

Raducanu won the first set and was serving for the match, but Krejcikova got a vital break.

It meant, from being 5-2 down in the second set, Krejcikova levelled it at 5-5.

Raducanu hit back to win the next game. A double fault from Krejcikova then saw the next game go to deuce but the Czech, a previous winner at both Wimbledon and the French Open, regrouped to take them into a tiebreaker.

Raducanu got onto the front foot and began to extend her lead, despite pressure from Krejcikova.

However Krejcikova overhauled the Briton with an overarm smash to grab a set point. Raducanu served up an ace to snuff out that threat and delivered another heavy serve to reach her second match point. The Czech defended it and they remained neck-and-neck in the tiebreak.

Eventually Krejcikova overhauled her to secure the tiebreak 12-10 to take them into a deciding set.

Krejckova then ran away with the third, taking a commanding 4-1 lead. Raducanu needed to hold serve in the sixth game but was broken again. That allowed Krejcikova to serve out the match.

She will next play Iga Swiatek in the quarter-finals.

Great Britain ease into Billie Jean King Cup semi-finals

Great Britain breezed to a 2-0 quarter-final win over Japan to set up a semi-final meeting with the USA in the Billie Jean King Cup.

Sonay Kartal got the British team off to a strong start in Shenzhen with a straight-sets win against Ena Shibahara, taking the first set 6-3 before winning a tie-break in the second to prevail 6-3 7-6(4).

Katie Boulter then faced Moyuka Uchijima and she too did not drop a set when winning 6-2 6-1 in just over an hour.

"It's another opportunity, I've been in this position twice before," Boulter said of the prospect of facing the USA.

"Myself, I know what to expect, they've got some world-class tennis players down the other end but they also don't know what we're capable of.

"We're going to have a free swing and get after them for sure, we've got nothing to lose and I'm very excited for this next round."
