Los Angeles, Mar 6 (EFE).- Swiss great Roger Federer is preparing to defend his title at the ATP World Tour Masters 1000 event in Indian Wells, California.
The event in Indian Wells will feature the top five men in the world, including Spanish star Rafael Nadal, who is on the comeback trail from a knee injury that sidelined him for seven months.
Federer knocked Nadal out of the tournament last year in the semifinals with a 6-3, 6-4 win in 91 minutes.
The 26-year-old Nadal, who won the Mexican Open in Acapulco this month, is coming off a 7-6, 6-4 loss to Argentina's Juan Martin del Potro in an exhibition match Monday at New York's Madison Square Garden.
The 31-year-old Federer, who has won 17 Grand Slam titles, could face Nadal in the quarterfinals at Indian Wells.
The BNP Paribas Open at Indian Wells is one of the tennis season's nine ATP World Tour Masters 1000 events, which rank only below the four Grand Slam tournaments and the season-ending ATP World Tour Finals in terms of ranking points and prestige.
