istanbul bayan escort (AP) - Top-seeded Elise Mertens retired from her opening match at the clay-court Istanbul Championship on Wednesday because of a leg injury.
The 26-year-old Belgian was losing 7-5, 4-1 to Sweden's Rebecca Peterson when she retired with pain in her right leg.
Mertens was runner-up to Sorana Cirstea last year.
Croatian player Petra Martic upset fourth-seeded Anhelina Kalinina of Ukraine 3-6, 7-5, 7-6 (5).
Later, Cirstea faces Dutch player Arantxa Rus in the second round. The 32-year-old Romanian last year ended a 13-year wait for her second career singles title when she upset Mertens in the final.
