Angelique Kerber has described her new found World Number one status as 'amazing'.
Kerber defeated Caroline Wozniacki in her semi-final in the semifinals of the US Open usurping current number one Serena Williams who lost against Karolina Pliskova to end 186 weeks at the top.
She will officially become Germany's first number one since Steffi Graf in 1996 when the new rankings are released next week.
"To be number one in the world sounds amazing," said second seed Kerber.
"For me it's amazing to be, after Steffi, the number one player from Germany".
In becoming number one, she also protects her compatriot's record of consecutive weeks at the top of the rankings as Williams' defeat to Pliskova of the Czech Republic leaves the American tied with Graf on 186 weeks.
Australian Open champion and Wimbledon runner-up Kerber, who won Olympic silver in Rio, will take on Pliskova in Saturday's final in New York, as she attempts to win a second Grand Slam title.
