Tennis fans have expressed their frustration over Emma Raducanu’s latest mid-match retirement, which happened during her semifinal match at the Korea Open in Seoul.The 2021 US Open champion retired in the third set against Jelena Ostapenko on Saturday. Notably, however, this match marked Raducanu's first semifinal since her triumph at the US Open last year.Raducanu, in fact, did not drop a set leading up to her final four clash with the 2017 French Open champion.The Brit started the match against Ostapenko on a positive note, taking the first set 6-4. While she further extended her lead by scoring a break in the second set, she was soon seen in some physical distress.Raducanu's movement seemed restricted after that, and she lost her momentum. Ostapenko grabbed the opportunity to claim the second set and then found herself leading 3-0 in the third when Raducanu decided to retire.The final score read 4-6, 6-3, 3-0 (ret.) in the Latvian’s favor.This is Raducanu’s fourth mid-match retirement of the season. The teenager previously retired in Guadalajara with a left hip injury, in Rome with a lower back injury, and in Nottingham with a rib injury.She cited a left glute injury as the reason for her withdrawal in Seoul.But tennis fans were not happy with Raducanu's reasoning, and on Saturday many of them expressed their displeasure with her frequent mid-match retirements. One fan was of the opinion that the young Brit should find a new career."Emma Raducanu needs to find a new career. It’s fucking pathetic how she is even ranked. She’s withdrawn from more matches than won over the past year and a half," the fan said.🧀@gromitspicksEmma raducanu needs to find a new career. It’s fucking pathetic how she is even ranked.

The then 18-year-old achieved the feat without dropping a single set throughout the tournament.But she experienced a steep decline in her performances thereafter. This year, Raducanu has managed to accumulate just 17 wins against 18 losses. Her best results have been quarterfinal finishes at the Stuttgart Open and the Citi Open, and most recently, reaching the semifinals of the Korea Open.At the US Open, where she was the defending champion, Raducanu bowed out in the opening round with a defeat to Alize Cornet. The loss saw the former World No. 10 fall to No. 83 in the rankings. She has since had a slight revival and is now ranked 77th, but the latest injury setback might be a cause for worry as she looks ahead to the rest of the season.
