Juan Martin del Potro defeated Julien Benneteau 7-6 (7/2), 6-3 on Sunday to win the Rotterdam World Tennis and deny the Frenchman's dream of a first career title. Del Potro played the last game with cotton wool stuffed up one nostril due to a bloody nose which came on after the previous game in which Benneteau saved four match points. But the Argentine second seed, who lost the final here a year ago to Roger Federer eventually defeated Benneteau, Federer's conqueror in the quarter-finals, with 13 aces and three breaks of serve.
