JOIN USNadal reigns supreme
The top seed, whose victory here last year made him the first man in the professional era to triumph in the same tournament six times in a row, showed few signs of letting his grip on the trophy loosen with another all-powerful display.
"King of Clay" Nadal first broke in the third game when his compatriot netted but Ferrer struck back immediately with his own break of serve thanks to an exquisite drop shot in the final of the first claycourt event of the European season.
However, Ferrer's joy was shortlived with Nadal breaking next game and winning the first set before seizing the initiative in the second with a superb passing shot only to be broken in the eighth game and then hitting back for 6-5.
He leapt into the air with delight when Ferrer hit the net to seal his victory. Ferrer defeated an injured Nadal in the last-eight of January's Australian Open but this time the world number one, who beat Fernando Verdasco in the principality last year in another all-Spanish final, was too strong on his forehand.
Nadal won every claycourt event he entered last year and few would bet against him repeating the feat this season with the defence of his French Open title due next month after trips to Barcelona and the Masters events in Madrid and Rome. The 24-year-old has arguably not been at his very best this week at the beachside event, and was pushed hard by Andy Murray in Saturday's semifinal, but even the odd problem with his serve or failure to kill off a point have not cost him.
Novak Djokovic beat Nadal in his previous two finals on hardcourts this year but he pulled out of this tournament with a knee injury, robbing fans of the chance to see whether the Serb could threaten the Spaniard on his favoured clay surface.
Roger Federer lost in the quarterfinals when the Swiss had seemed on a collision course towards the final with his great rival Nadal, but fourth seed Ferrer put up a decent fight instead with his family watching from the sun-kissed galleries.
