Li routs Vinci to reach Wimbledon quarterfinals
The 31-year-old Chinese player broke the 30-year-old Vinci six times to wrap up the win in just 55 minutes on Court 3.
The sixth-seeded Li will next play the winner between No. 4 Agnieszka Radwanska of Poland and Tsvetana Pironkova of Bulgaria.
The 11th-seeded Vinci was trying to make her first Wimbledon quarterfinal, having also reached the fourth round last year.
