Zidansek, 20, reached her maiden WTA quarter-final with a 6-4 2-6 6-4 victory in a thrilling clash on Thursday. Her reward is a last-eight meeting with Laura Siegemund, the German having knocked out Kateryna Kozlova with an easy 6-0 6-3 triumph. Anastasija Sevastova was pushed hard but the third seed levelled her career-best winning streak of seven wins in a row, coming through 6-2 6-7 (5-7) 6-4 against Irina Bara. The Bucharest Open champion had two match points in the second set but the Romanian lucky loser forced her to go the distance in booking a quarter-final against Aliaksandra Sasnovich. Fifth seed Sasnovich beat Russia's Evgeniya Rodina 7-5 6-2 in the first match of the day. At the JiangXi Open, third seed Magda Linette and sixth seed Zheng Saisai safely moved into the quarter-finals on Thursday, defeating Eri Hozumi and Karman Thandi respectively.
