Say it ain’t so! Current world no.3 and all-around pretty decent player Roger Federer has just announced that he won’t be participating in the upcoming Shanghai Masters next month. It’s the second time Federer’s pulled out from competing in Shanghai, after the longtime world no.1 declined his Masters invitation in 2009. Current world no.1 Novak Djokovic is also unlikely to make it to Shanghai, as a recent back injury will require between three to six weeks to heal. It comes as little surprise that two of the top three players in the ATP Tour would miss out on the upcoming tournament in Shanghai, as the Masters follow both the U.S. Open (the year’s fourth and last Grand Slam) and Davis Cup matches, two must-play events on the ATP schedule. Players have recently threatened to strike due to the grueling schedule set up by the International Tennis Federation, and will meet in Shanghai during next month’s Masters to discuss the situation.
