Nadal triumphs in singles return

Rafael Nadal made a triumphant singles return after a seven-month absence, beating Argentinian qualifier Federico Delbonis 6-3, 6-2 in the second round of the ATP clay-court tournament here.

The 11-time Grand Slam champion from Spain hadn't played since a shock second-round exit from Wimbledon in June.

A torn tendon and inflammation in his left knee had kept him out of the London Olympics and the 2012 US Open, while a virus further delayed his return to action this year.
