The world No. 1

Having ended a two-and-a-half-year wait for a grand slam title with victory at Wimbledon, Roger Federer is back at the top of the rankings; not bad when you consider he was forced to repeatedly brush off questions over his future just 12 months ago. He may have missed out on Olympic gold at London 2012, but he bounced back in emphatic fashion in Cincinnati last week, winning his first event on his return to the hard courts and doing so without dropping his serve, and to add insult to injury he bageled Djokovic in the final. Arguably the most in-form man in the field, he is tough to bet against at odds of 5/2 .
