Federer makes short work of Nishioka in clammy New York

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 US Open crown and first since 2008.

Next up for the Swiss is a second-round clash with unseeded Frenchman Benoit Paire.
