Dubai, United Arab Emirates -- (Sports Network) - French Open champion Rafael Nadal, Australian Open titlist Novak Djokovic and former world No. 1 Andy Roddick were among Tuesday's opening-round winners at the $1.426 million Dubai Tennis Championships.

The second-seeded Nadal came from behind to beat German Philipp Kohlschreiber 3-6, 6-1, 6-4 in 2 hours, 22 minutes, while the third-seeded Djokovic handled Croat Marin Cilic 6-4, 6-3 and a sixth-seeded Roddick topped fellow former top-ranked star Juan Carlos Ferrero 6-2, 6-4 at Dubai Tennis Stadium.
