British number two Emma Raducanu retired from her Korea Open quarter-final against Daria Kasatkina with an injury to her left foot.<\/b><\/p>\n
Raducanu struggled with the issue in the previous round against Yue Yuan<\/a> and continued to look uncomfortable in the opening exchanges against the Russian top seed.<\/p>\n The 21-year-old was broken in the second game but, despite breaking straight back, struggled to serve and was unable to chase returns around the court.<\/p>\n She needed a medical time out after the fifth game and decided she could not continue after losing the opening set 6-1.<\/p>\n Kasatkina will play compatriot Diana Shnaider in the semi-finals after she beat Ukraine’s Marta Kostyuk 7-6 6-3.<\/p>\n The match will take place later on Saturday after rain postponed play on Friday.<\/p>\n “I feel sorry for Emma,” said Kasatkina after the match. “It’s a pity to get injured, especially in the deeper stages of the tournament. I wish her a speedy recovery.”<\/p>\n Raducanu had been hoping to reach her first semi-final above WTA 250 level since her 2021 US Open victory.<\/p>\n The world number 70 has sustained a number of injuries since her Flushing Meadows triumph.<\/p>\n She was restricted to just nine matches in 2023 due to having surgery on both of her hands and left ankle.<\/p>\n Raducanu returned at the start of this year and reached the second round of the Australian Open, before skipping the French Open<\/a> to focus on her fitness.<\/p>\n She reached the fourth round at Wimbledon to return to the world’s top 100<\/a>, but suffered a first-round defeat by American Sofia Kenin at last month’s US Open.<\/p>\n<\/div>\n
