Firing Federer is in a New York state of mind

Roger Federer hopes to mark the 10th anniversary of his first US Open title with a sixth triumph in New York and become the oldest Grand Slam champion in more than 40 years.

In an astonishing reversal of fortunes, the 33-year-old, written off as a relic of the game when he slipped to a fourth-round loss to Tommy Robredo 12 months ago, finds himself perfectly positioned to win a staggering 18th major.

Buoyed by claiming a sixth Cincinnati title - his 80th career crown - and with long-time rival Rafael Nadal again sidelined with injury, the Swiss is relishing the twilight of his career.
