Roger Federer defeated Robin Haase in three sets, 4-6 6-1 6-1, to reach the ABN Amro semifinals in Rotterdam and be world No. 1 again. 'Getting to No. 1 and enjoying it right here at 36, almost 37 years old, is an absolute dream come true, I can’t believe it', an emotional Federer said. At 36 age, he becomes the oldest ever to be at the first position in the ATP singles rankings, breaking Andre Agassi's record.
