Kerber triumphs and aims to be a number one hit
Angelique Kerber took another step towards becoming world number one as she sailed past Roberta Vinci to reach the US Open semi-finals.
Kerber will snatch top spot away from Serena Williams if she equals or betters the American's performance at Flushing Meadows and she turned up the heat with a ruthless 7-5 6-0 victory.
Vinci was the instigator of one of the greatest upsets in tennis history here last year when she beat Williams in the semi-final.
The 33-year-old served for the opening set but could not close it out as Kerber raced away in the second to secure victory in one hour and 18 minutes.
"I think the key of the match was the first set," Kerber said. "It was really close and tough."
Kerber has enjoyed a superb year, after winning her first major title at the Australian Open before running Williams close in the final at Wimbledon.
Williams must now reach the final again in New York to have a chance of staying world number one and if she plays Kerber, the American would have to win.
"When I was a kid I was always dreaming of being the number one," Kerber said.
"If the day will come, it will be amazing."
