"My body needs rest": Iga Swiatek withdraws from Mutua Madrid Open

HIGHLIGHTS: Swiatek dismisses Sabalenka for Stuttgart crown

The question of how much further Iga Swiatek can increase her 23-win match streak will have to wait another tournament week.

Fresh off winning her fourth consecutive title after tasting victory in Stuttgart, the world No. 1 pulled out Wednesday from the Mutua Madrd Open with a right shoulder injury. Prior to her latest title run, Swiatek won the 1000 event in Doha before sweeping the Sunshine Double at Indian Wells and Miami.

“It's time to take care of my arm that has been fatigued since the Miami Open and I haven’t had a chance to handle it properly,” the 20-year-old wrote on her Instagram Story.

“I need a break from playing so intensively in order to treat my arm well and that’s why, unfortunately, I have to withdraw from the Mutua Madrd Open. My body needs rest. I’m going to take some time to prepare for Rome and Paris. See you soon there.”

The Pole is the defending champion at Rome’s Internazionali BNL d'Italia, where she double bageled Karolina Pliskova in last year’s final. In her Roland Garros title defense attempt, Swiatek was eliminated in the quarterfinals by Maria Sakkari. When returning to action, Swiatek will enter her next match having won 32 of the last 33 sets she’s contested.

US Open finalist Leylah Fernandez moves into Swiatek’s spot atop the Madrid draw as the newly-assigned No. 17 seed and plays qualifier Andrea Petkovic in her opener. Paula Badosa, who debuts as world No. 2 this week, is seeded second.
