Emma Raducanu retired from her first-round match against Camila Osorio at the Qatar Open, two days after losing the Transylvania Open final.

The British number one called the trainer out to have her blood pressure taken after being broken at the start of the third set, and after going 2-0 down in the decider to Colombia’s Osorio, she forfeited the match.

Raducanu had won the first set 6-2 before conceding the second 6-4.

On Saturday the 23-year-old featured in her first final since her 2021 US Open triumph, but was beaten in little more than an hour by Sorana Cirstea at the Transylvania Open.

Raducanu also had her blood pressure taken in that match, and afterwards revealed her fitness had been affected because she was “battling a bit of a chest infection”.

Raducanu started strongly against Osario, opening up a 3-0 lead before going on to secure the first set 6-2.

Osario showed signs of mounting a comeback late in the first set and her revival continued in the second as she secured her first break of the match to take a 3-2 lead.

Osario was forcing Raducanu into mistakes and she wrapped up the second set 6-4 when the Briton put a forehand long.

After saving two break points at the start of the deciding set, Raducanu was broken again as she gingerly failed to chase down a drop shot, before calling out the trainer.

Raducanu returned to action briefly, but after Osario consolidated her break, the Briton made her way to the net to inform the umpire she was retiring from the match.

Raducanu has been plagued with injuries and has struggled to find consistency on the WTA Tour since her historic victory at the US Open.

In October, Raducanu retired in the first round of the Wuhan Open after having her blood pressure and temperature taken by the doctor.

In January, she split with her latest coach, Francis Roig, after a second-round exit at the Australian Open.

Spaniard Roig, who she had been working with since the summer of 2025, was the ninth person to coach Raducanu since 2021.
