In the second round of Wimbledon, top seed Simona Halep looked to be in danger of joining the heap of defeated seeds, but the world No.1 overcame a slow start and won ten games in a row from a 3-5 deficit in the first set to defeat China’s world No.126 Zheng Saisai 7-5 6-0.
Third seed Garbine Muguruza suffered the earliest exit of a defending champion at Wimbledon since Steffi Graf was defeated in the first round in 1994. The Spaniard lost her second-round match to Alison Van Uytvanck 5-7 6-2 6-1. The Belgian world No.47 lost the first set despite holding a 4-2 lead, but dominated the remainder of the match to move into the third round of Wimbledon for the first time and record her first Top 10 victory.
After Day 4 and completion of second-round action, we have only two seeds alive among the Top 8 seeds, No.1 Simona Halep and No.7 Karolina Pliskova.
