BUENOS AIRES - Rafael Nadal has had his request for a wildcard invitation to next week's Argentina Open accepted as the Spaniard rejigs his schedule after his shock Australian Open exit. The world number five lost in the first round of a Grand Slam for just the second time to fellow Spaniard Fernando Verdasco. After his unexpectedly early departure the 29-year-old travelled to Mallorca to start training for what could be a make or break year on clay, starting now with the defence of his title in Buenos Aires. "I want to thank the organisers of the Argentina Open for giving me this wild card to play in Buenos Aires," he told the ATP website. "The times that I've played in Argentina have been special and full of good memories because the people are some of the best in the world.”
