The sensational news is that the number one seed was knocked out of Wimbledon on Friday. The bad news for thrill-seekers is that this was not the perennial men’s champion, Roger Federer, who sailed into the last 16 with his customary serenity, but the rather less well-known women’s number one, Ana Ivanovic of Serbia.

Ivanovic’s status looked highly questionable on Wednesday when she scraped an extremely fortuitous victory against the world number 97, Nathalie Dechy. This time she was up against number 133, Jie Zheng of China. She was blown away 6-1 6-4.
