On Thursday, ATP main draw play will begin at the BNP Paribas Open in Indian Wells, the first of nine Masters 1000 events on the 2013 calender.
In 2012, No. 3 seed Roger Federer captured the title over surprise finalist John Isner 7-6(7), 6-3. Isner, the No. 11 seed, pulled off a huge upset in one of the most memorable matches of the year in the semifinals when he defeated world No. 1 Novak Djokovic 7-6(7), 3-6, 7-6(5).
Both Federer and Isner are hoping to repeat their success from last year and turn around what has been a disappointing 2013 up to this point. Federer has yet to reach a final in the three events he has played, and Isner has lost to a lower-ranked opponent in all five of his tournaments this year.
This will also be the first time since Wimbledon that Djokovic, Federer, Andy Murray and Rafael Nadal will be in the same draw as Nadal missed several months due to a knee injury. He is coming into Indian Wells in good form after winning two straights events on clay in Brazil and Mexico.
If Murray can walk away from the BNP Paribas Open victorious, he will take over the No. 2 ranking from Federer in the process. Djokovic will be a threat as always as he attempts to remain on top of the game and reclaim the title that he won in 2011.
With the "Big Four" back in action and major ATP points at stake over the next two weeks in Indian Wells, you can look forward to some high quality tennis in the desert with some of the sport's biggest rivalries hopefully on the schedule.
