Roger Federer should be the freshest of the leading contenders when the Cincinnati Masters kicks off this week.
Unlike his main rivals, Federer opted to miss the Toronto Masters (as one of the richest sportsmen in the world he can afford the fines !) and spend a few days recuperating at his family chalet after the Olympics before hitting the practise courts in the States.
It all bodes extremely well for Federer's chances of winning a fifth Cincinnati title, an event he's dominated over the past few years. He should certainly fare better than last year when he lost in the quarter-finals to Tomas Berdych.
Andy Murray is defending his title but he picked up a slight knee strain in Toronto while Novak Djokovic is surely going to be exhausted after reaching the latter stages in Canada straight after the Olympics.
All in all, the effect of the Olympics has reverberated through the tournaments of July and August. Tournament directors have been plagued by constant withdrawals and the Cincinnati organisers have already seen Rafael Nadal, Fernando Verdasco, Nicolas Almagro, Gael Monfils and Jo-Wilfried Tsonga pull out.
While Federer turned 31 earlier this month, Andy Roddick will be trying to get back into the top 20 on the eve of his 30th birthday. Roddick won Cincinnati in 2003 and 2006 but it will be a big surprise if he threatens this year.
