Katie Boulter failed to secure a resounding victory against five-time Grand Slam champion Iga Swiatek as Britain’s hopes of reaching the United Cup semi-finals were ended by Poland.
Boulter, 28, needed victory to send the best-of-three into a doubles decider but lost 6-7 (4-7) 6-1 6-4 to world number two Swiatek in Sydney.
The two players warmly embraced each other in front of the net after a thrilling fight that lasted nearly three hours.
“I’m exhausted. I’m happy I won, so I didn’t have to play doubles,” Swiatek said.
“That match was so crazy, there were so many dynamic changes.”
Britain’s hopes rested on Boulter causing a shock against the five-time major champion after Billy Harris narrowly lost to former world number six Hubert Hurkacz.
Harris, 29, pushed 16th-ranked Hurkacz in the best-of-three opener before losing 7-6 (7-3) 7-5.
Poland, who were one of the favorites before the tournament, will face Kazakhstan in the last four on Friday.
Harris, a late bloomer who has made huge strides over the past two years, was playing as Britain’s leader, with Jack Draper nursing a hip injury and Cameron Norrie starting the season at an ATP event in Hong Kong .
As in his defeats against the Argentinian Tomas Martin Etcheverry and the Australian Alex de Minaur, the world number 125 performed well against a much higher ranked opponent, Hurkacz.
However, he lacked the tools to achieve the biggest victory of his career and provide a platform for Great Britain to reach the final four.
Harris served solidly throughout, but failed to break 2021 Wimbledon semi-finalist Hurkacz and came up short in the deciding moments.
A costly mistake by Harris – a long error with an overhead – resulted in an early mini-break in the first set tie-break, which allowed Hurkacz to take a clinical lead.
Harris quickly reset to create three break points in the second game, only for Hurkacz to fight back from 0-40 down with five huge serves getting him out of trouble.
Another close set saw Harris finally broken in the 11th game and, with the wind taken out of the Briton’s sails, Hurkacz quickly wrapped up the victory with a hold at love.
Burrage holds match point before losing in Auckland
British fans were left even more disappointed when Jodie Burrage missed the chance to reach the quarter-finals at the WTA season-opening event in Auckland.
The British number seven held a match point in the deciding set against her American opponent Hailey Baptiste but was unable to convert and lost 5-7 7-5 7-6 (8-6).
Burrage, 25, is trying to revive his career after missing much of last season with wrist and ankle injuries.
After securing a late place in the main draw in Auckland as a lucky loser, she made the most of her opportunity with a maiden victory against New Zealand wildcard Vivian Yang.
Despite losing to 92nd-ranked Baptiste, Burrage’s performance will come in handy heading into the Australian Open, where she is playing in an injury-protected ranking.
