Second seed Garbine Muguruza is out of Wimbledon after losing in the second round in straight sets to Slovakia's world number 124 Jana Cepelova. The 22-year-old French Open winner, who lost last year's final to Serena Williams, lost 6-3 6-2 on Court One. Cepelova, 23, will now face Czech 29th seed Lucie Safarova in the third round. Third seed and 2012 finalist Agnieszka Radwanska survived a scare, saving three match points to win in three sets against teenager Ana Konjuh. Five-time Wimbledon champion Venus Williams progressed to the third round with victory in three sets over qualifier Maria Sakkari.
