World number one Roger Federer picked up his 58th consecutive win on grass to breeze into Sunday's final of the Halle ATP tournament by seeing off Germany's Nicolas Kiefer 6-1, 6-4 in Saturday's semi-final.

Federer has yet to drop a single set here at Halle, his traditional grass-court warm-up for Wimbledon later this month where he will bid to win a sixth consecutive title.

In Saturday's one-sided semi-final, Federer took the first set 6-1 in just 22 minutes until Kiefer rallied briefly in the second at 3-2 up, but squandered four break points.

Federer levelled the set at 3-3, before breaking Kiefer for a 5-4 lead and serving for the match Federer used his first match point to claim victory in just 65 minutes.

"I served well roday and I could go through Nicolas' second serve - that helped me a lot, especially in the first set," said the Swiss.

He is looking to win his fifth Halle final on Sunday where he will face Germany's Philipp Kohlschreiber who put out American second seed James Blake 6-3, 7-5.

"I was hitting some good shots although Kiefer had some nice ones from the baseline," said Federer. "I am happy to be in another final."

With his arch-rival and world number two Rafael Nadal in action at the Queens' club tournament, Federer said he is paying little attention to the Spaniard's transition from clay to grass.

"I don't really follow what he is doing," said Federer.

"I don't know what has to happen before you guys (the media) understand Nadal is not only the claycourt specialist, but a superb all-rounder, he has been in a Wimbledon final twice.

"I only know that (Andy) Roddick and (Ivo) Karlovic are there, so there are good guys he has to beat.

"However, I am surprised about my good form and the way how I manage to keep calm and not get nervous or under pressure on court."
