Rafa Nadal... perfect ending to a fine season.

Rafa Nadal’s growing domination of great rival Roger Federer continued with a comprehensive 7-5 6-3 victory in the semi-finals of the ATP World Tour Finals yesterday.

The mid-afternoon clash was not one of the best in their 32-match series as Federer faded badly in the second set to hand Nadal his first victory over him on an indoor court.

Nadal was thrashed 6-3 6-0 by Federer at London’s O2 Arena two years ago but after a tight first set he proved too strong for the 32-year-old Swiss who looked weary after his three-set victory over Juan Martin Del Potro on Saturday.

The year will now have a mouth-watering grand finale with Nadal up against defending champion and world number two Novak Djokovic today.

Last night, Djokovic beat Swiss Stansilas Wawrinka 6-3 6-3 in the second semi-final.

Federer had the first chance yesterday when he put the world number one in trouble on serve in the sixth game but Nadal held firm and broke Federer’s serve to lead 5-4.

The Swiss played a scintillating point at 15-30 in the next game, ending an exhausting baseline exchange when he rifled a forehand down the line and Nadal ballooned out a forehand to hand Federer the break back.

However, a third consecutive break of serve gave Nadal a second chance to take the opener and this time he made no mistake with a clinical love game.

When a Federer forehand nose-dived into the net on break point at 2-2 the belief seemed to drain out of the 32-year-old and the end came quickly as Nadal extended his career record over the 17-times grand slam champion to 22-10.

“It’s the perfect way to finish one of the best seasons of my career to have the chance to win a title I’ve never won so far,” Nadal, who has won everything in the sport apart from this particular tournament, said.
