World number one Roger Federer [ Images ] cruised to his fifth Halle Open title in Germany [ Images ] on Sunday, beating Philipp Kohlschreiber 6-3, 6-4.

Federer, who was heavily defeated by Rafael Nadal [ Images ] in the French Open [ Images ] final last weekend, was rarely troubled by his German opponent, extending his winning streak on grass to 59 matches ahead of Wimbledon [ Images ] which starts on June 23.

"I played great tennis all week. I didn't lose my serve once, which I don't think I've ever managed before in a tournament, so it's very special for me, and I'm really pleased about it," Federer told German television.

Federer has traditionally used the Halle tournament as a warm-up for Wimbledon, but skipped the event a year ago after losing to Nadal at Roland Garros [ Images ].

The Swiss, who also failed to drop a set all week, said he is fit and ready for the third Grand Slam tournament of the year where he aims to break the record he shares with Bjorn Borg [ Images ] of five consecutive wins.

"It's obviously a good omen to win here in Wimbledon, sorry, Halle -- the Wimbledon of Germany," he said, laughing.
