Federer to face Kohlschreiber in Halle final

World number one Roger Federer swept into the final of the Halle Open on Saturday with a 6-1 6-4 victory over Nicolas Kiefer of Germany.

Federer, four times winner of the grass tournament in Halle which the Swiss uses as a warmup for Wimbledon starting on June 23, extended his winning streak on the surface to 58 games.

Federer will play Germany's Philipp Kohlschreiber in Sunday's final.

"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."

"Overall, I played a really good game," he told reporters.

Kohlschreiber upset second seed James Blake of the United States in the second semi to win 6-3 7-5.
