| Where other players had slogged through long 
				rallies as the temperature hit 90 Fahrenheit (32C), Federer kept 
				his time on court to a minimum with a masterclass of 
				serve-and-volley tennis, pulling the industrious world number 
				177 from one side of the court to the other at will.
 Federer, the second seed, broke the Japanese lefthander in the 
				opening game of the one-sided encounter and never looked back, 
				rattling through his service games with a minimum of fuss to 
				wrap up the first set in 28 minutes.
 
 "I'm happy to be back in New York, healthy - the last couple of 
				years have been difficult so it's nice to be back, feeling 
				really good," Federer said courtside after the win.
 
 "I'm happy I played well tonight and Nishioka was a tough 
				opponent. He's got fast legs and a bright future ahead of him. I 
				was very happy with how I played."
 
 The Swiss took 35 minutes to close out the second set and, with 
				Nishioka firmly on the ropes, started the third by racing to a 
				4-0 lead before his Japanese opponent held serve.
 
 Nishioka rallied briefly at the end, denying Federer the chance 
				to serve out the set and battling back to 5-4 with his first 
				break of serve.
 
 But Federer put his beleaguered opponent out of his misery in 
				his next service game, wrapping up the victory in one hour and 
				52 minutes.
 
 Federer, who has never lost an opening round match at Flushing 
				Meadows, said he would try to continue that streak until he 
				finally hangs up his racket.
 
 "I'm happy I never stumbled at the first hurdle. It's almost 
				time to retire, but not yet," the 37-year-old said with a smile, 
				adding that the conditions had been tough.
 
 "I think particularly tough for us Europeans, we don't get this 
				type of humidity where we live and grow up. It's something we 
				have to get used to," added Federer, who is looking for a sixth 
				U.S. Open crown and first since 2008.
 
 Next up for the Swiss is a second-round clash with unseeded 
				Frenchman Benoit Paire.
