Serena Williams encountered few problems eliminating Hungarian qualifier Melinda Czink in the second round at Wimbledon on Thursday.
The four-time champion, seeded sixth, needed barely an hour to prevail 6-1, 6-4 with the help of 10 aces.
In round three the American meets 25th seed Zheng Jie of China, who ousted Canada’s Aleksandra Wozniak 6-4, 6-2 earlier Thursday.
Elsewhere, French Open runner-up Sara Errani of Italy breezed past 29-year-old Briton Anne Keothavong 6-1, 6-1.
Tenth seed Errani next plays Kazakh wild card Yaroslava Shvedova, who beat Dutch world No. 86 Kiki Bertens 6-4, 6-4.
