Rotterdam, Netherlands  - Andy Murray won his second title of the season as he beat Rafael Nadal in back-to-back matches, taking a 6-4, 4-6, 6-0 victory on Sunday at the ABN-AMRO World Tennis.

The Scot managed to recover his forces after dropping a second serve riddled with seven breaks of serve as he defeated the top seeded Spaniard five months after a semi-final victory in their series at the US Open.

Nadal took treatment on his right thigh after the third game of the second set and was feeling the problem as Murray swept the third for victory.

The Scot appeared fully fit after complaining of an ankle problem during his semi-final win a day before. Murray, ranked fourth in the world, claimed the tenth title of his career.

He also began turning his record against Nadal, which now stands at two wins and five losses.

"I know that Rafa hurt his thigh in the second set. But he's so good he almost beat me on one leg anyway," joked Murray. "He's still had a great start to the year, winning the Australian Open."

Murray became the first Briton to win Rotterdam after three runner-up finishes by Tim Henman. He stands 13-1 on the season after winning in Doha during the first week of the year.

Nadal made no mention of his injury, which proceeded a run of breaks in the second set.

"I came here tired form the Australian Open, but this was still a very important result for me," said the world number one. "Andy is off to a good season.

"This was a good week for me, especially to reach this final."

Nadal's loss was only his second of the season after losing to Gael Monfils in the Doha quarter-finals in early January.

Murray came out looking fully fit with no apparent strapping on the ankle injury which bothered him during his quarter-final victory over Mario Ancic.

The second seed quickly moved into position with a break of Nadal for 4-2, then polished off the first set three games later with his third ace.

The level of the second set dropped by a huge margin, with seven breaks of serve in a row determining the state of play.

Nadal started the run in the fourth game as he broke Murray and ended the set after 52 minutes with a fourth break of the Scot.

The final set of the contest flew by as Murray preyed upon the injured Nadal to wrap it all up in just under two hours. dpa
