Wimbledon Day 4 Highlights: Top-ranked Simona Halep won the last 10 games to beat Saisai Zheng of China 7-5, 6-0 in the second round of Wimbledon. Saisai led 5-3 in the first set but Halep broke back for 5-5 and cruised the rest of the way against her 126th-ranked opponent. Novak Djokovic overcame an apparent thigh problem to beat Horacio Zeballos 6-1, 6-2, 6-3 and reach the third round at Wimbledon. Guido Pella of Argentina came from two sets down to stun third-seeded Marin Cilic at Wimbledon, beating last year’s finalist 3-6, 1-6, 6-4, 7-6 (3), 7-5 in the second round. Cilic looked headed for a routine victory before the match was suspended by rain in the third set on Wednesday but the former U.S. Open champion couldn’t find the same rhythm on Thursday.
Top seed Roger Federer’s bid for a ninth Wimbledon title gathered momentum after he cruised into the third round with a 6-4 6-4 6-1 win over Slovakian world number 73 Lukas Lacko on Wednesday. The 36-year-old Swiss did not face a single break point and struck 48 winners as he extended his winning streak to 26 successive sets at the All England Club. Federer will next face Germany’s Jan-Lennard Struff, who edged past Croatia’s Ivo Karlovic in five sets. Seven-time champion Serena Williams proved too powerful for Bulgarian Viktoriya Tomova in a 6-1 6-4 win as she continued her steady progress on her return to Wimbledon, having missed last year’s event after taking a maternity leave.
