Im very happy, the 24-year-old Serb said after beating the Dane for the first time since the 2008 French Open,which she went on to win.

The Swiss,who had never previously played the 21-year-old,will next face Brazilian Thomaz Bellucci,who benefited from a walkover when Russian Nikolay Davydenko withdrew due to illness. I was impressed (by Raonic). He played great and made it hard for me by winning that first set tiebreaker. He kept himself in the match till the very end,and obviously put a lot of pressure on me. I think the longer I stayed out there the better I started feeling, Federer said.
