World number one Iga Swiatek has withdrawn from the bett1open next week due to a shoulder injury.
Swiatek, who won her second grand slam title at the French Open last weekend, was due to start her grass-court season in Berlin a fortnight before Wimbledon gets under way.
But the all-conquering Pole pulled out of the WTA 500 tournament on Friday, revealing she will take time to rest ahead of the third major of the year at SW19.
Swiatek tweeted: “Due to a recurrent discomfort I am feeling in my shoulder, unfortunately I need to withdraw from the bett1open in Berlin.
“I’m sorry I will not be able to play there. I will focus on recovery and rest in order to be ready for Wimbledon.”
Swiatek beat American teenager Coco Gauff 6-1 6-3 to regain the title at Roland Garros last Saturday.
That took the 21-year-old’s winning run to a staggering 35 matches, one more than Serena Williams’ best streak back in 2013.
Venus Williams is the only other woman since the start of 2000 to have reeled off 35 consecutive victories, while Swiatek and Serena Williams are the only women in the same period to have won six titles in the first six months of a year.
Swiatek was beaten by Ons Jabeur in the fourth round at Wimbledon last year but is a strong favourite to lift the Venus Rosewater Dish for the first time next month.
