For the first time this year, the entire ATP top 20 will be taking the court in the same tournament. Organizers of next week's Shanghai Rolex Masters announced on Wednesday that each of the top-20 men in the world will be competing in the Masters 1000 event.
The field of 44 will include five Grand Slam champions (Rafael Nadal, Roger Federer, Novak Djokovic, Juan Martin del Potro, Andy Roddick), five Slam finalists (Tomas Berdych, Robin Soderling, Marcos Baghdatis, Andy Murray, Jo-Wilifred Tsonga), nine Masters 1000 champions (Nadal, Federer, Djokovic, Murray, Roddick, Berdych, Tsonga, Nikolay Davydenko, Ivan Ljubicic) and three players who have hit No. 1 in the rankings (Federer, Nadal, Roddick).
How rare is it to have the top 20 all at the same tournament? It hasn't happened once this year, even at a Grand Slam. (Del Potro's injury is mostly to blame for that. Interestingly, now that he's out of the top 20, his presence in Shanghai doesn't even count for this stat.)
Shanghai is the penultimate Masters 1000 event on the 2010 schedule.
