Tennis-Federer routs Wawrinka, sets up 1-2 showdown with Djokovic

By Larry Fine NEW YORK, Sept 11 (Reuters) - Five-times champion Roger Federer reached his first U.S. Open final in six years as he raced past fellow Swiss Stan Wawrinka 6-4 6-3 6-1 at Flushing Meadows in the semi-finals on Friday. The second-seeded Federer, in remarkably sublime form at the age of 34, set up a delectable one-two showdown in Sunday's final against Australian Open and Wimbledon winner Novak Djokovic. The top-seeded world number one from Serbia advanced to his fourth grand slam final of the year with a 6-0 6-1 6-1 romp over defending champion Marin Cilic of Croatia, who was hampered by an ankle injury. Federer, the all-time grand slam singles king with 17 titles, will be gunning to add to his record haul for the first time since the 2012 Wimbledon. (Editing by Andrew Both)
