Hong Kong-bound Angelique Kerber downs Caroline Wozniacki for place in US Open final
New world number one will face Serena Williams’ conqueror Karolina Pliskova in Flushing Meadows final

Angelique Kerber marked her elevation to the world number one ranking by reaching the US Open final on Friday with a 6-4, 6-3 victory over Caroline Wozniacki.
The 28-year-old left-hander, who won the Australian Open in January and was Wimbledon runner-up in July, is the first German woman to reach the final in New York since Steffi Graf in 1996.
She will emulate Graf as US Open champion if she gets the better of Karolina Pliskova, who stunned Serena Williams 6-2, 7-6 (7-5) in her semi-final, in Saturday’s championship match.
Graf is also the only other German woman to achieve the top ranking.

Just moments after becoming the oldest first-time world number one, Kerber raced out of the blocks against the Dane, a two-time runner-up at the tournament.
