Beating leading Dutch player Robin Haase 4-6, 6-1, 6-1 in the quarterfinals at the ABN AMRO World Tournament means Federer becomes the oldest player — male or female — to top the world rankings, surpassing Andre Agassi, who held the record at age 33.
“Getting to No. 1 and enjoying it right here at 36, almost 37 years old is an absolute dream come true,” Federer said. “I can’t believe it.”
Federer will leapfrog 31-year-old Rafael Nadal to No. 1 when the rankings are updated on Monday.
Also a record will be the five-years-plus which have elapsed since Federer was last No. 1, and the 14 years since he first reached the top spot.
“This one, because I’m a little bit older, is a little bit more special maybe, because there’s just so much that has to go into it, so much has to be right for it to work out, and it did so. It’s a very deep satisfaction,” Federer said.
Federer did have some fun at his expense on Twitter:
