Emma Raducanu has pulled out of next week’s Berlin Open after suffering more back issues at the HSBC Championships. But the British No.1, who has now little hope of getting a seeding at Wimbledon, is still planning to play Eastbourne the week before the start of Wimbledon.

The former US Open champion first suffered back spasms before the Australian Open in January and again at the Strasbourg Open last month.

And Raducanu, 22, needed a medical timeout for treatment and took painkillers during her quarter-final defeat at the HSBC Championships.

In her post-match press conference, she said she would have to re-consider entering the WTA 500 event in the German capital. And asked if she was an fitness doubt for Wimbledon, she said: “I don’t know” and added:”It's been lingering for the last few weeks, and I have had back issues before.

“I think it's just a vulnerability of mine. I know I need to take good care of it. I'm not overly concerned that it's something serious, but I know it's something that's very annoying and needs proper and careful management.”

After treatment this morning, she has now pulled out of the Berlin Open but her team insists she is still confident of playing the WTA 250 event in Eastbourne starting on June 23. The grasscourt Grand Slam starts in SW19 a week later on June 30.

The world No.37 needed to make the final at Queen’s Club or go on a deep run in Berlin to break into the world’s top 32 by June 23 and secure a Wimbledon seeding.

But speaking after her straight sets defeat to No.1 seed Qinwen Zheng at Queen’s Club, Raducanu said: “I think being seeded obviously helps in Masters, helps in Slams and a lot of tournaments so you're not playing one of the top players early rounds.

“But I think maybe my goals have slightly shifted from being seeded to actually improving my game, and when I play those top players, making it closer and feeling more competitive rather than just feeling: ‘Okay, I maybe get to the third round of a slam but then lose comfortably to one of the top players’. I think I'd rather have a more competitive match, even if that means losing first round, second round. I think that, to be honest, is how I feel right now.”
