Federer and Berdych make final

Roger Federer and Tomas Berdych will meet in Sunday's Madrid Open final after beating Janko Tipsarevic and Juan Martin del Potro respectively.

Federer will win this event for the third time if he sees off the Czech.

A 6-2 6-3 victory took Federer into his 104th career final, while Berdych edged out Del Potro 7-6 (7/5), 7-6 (7/6) in the other semi-final.

Federer, a winner of this event in 2006 and 2009, has benefited from the early exits of both Rafael Nadal and top-ranked Novak Djokovic on the blue clay which has attracted criticism for being slippery.

And he had few problems on Saturday, wrapping up victory in 67 minutes and hitting 25 winners and eight aces in the process.

The Swiss excelled in his service games and took control of the first set in the fourth game when he broke Tipsarevic and wrapped up the set when he repeated the feat two games later.

And the end was in sight for the man who knocked out Djokovic when he was broken in the fourth game of the second set, giving Federer the incentive he needed to close out the contest.

Another success inthe final against sixth seed Berdych will see Federer replace Nadal at number two in the ATP Rankings.
