In form Wimbledon champion Andy Murray wasted little time getting his US Open campaign off to a flying start.
The Brit, seeking his second title at Flushing Meadows and first since 2012, breezed by dangerous Czech Lukas Rosol 6-3 6-2 6-2 in less than two hours to round out play on Arthur Ashe Stadium on the second day.
Second seed Murray, looking ominous in all black, effortlessly advanced without facing a single break point.
“I served very well,” said Murray, who set up a second round encounter against Marcel Granollers of Spain.
“It was a tough start to the match, he had a few chances early on but once I got the break up, I played well.”
Joining Murray in the second round is the man he beat for Olympic gold in Rio, Argentine Juan Martin del Potro.
The 2009 US Open champion continues to enjoy good form and what the 27-year-old hopes is the start of a career resurgence after three wrist surgeries.
Del Potro beat fellow Argentine Diego Schwartzman 6-4 6-4 7-6 (7-3). “I am so glad to be part of this tournament once again after three years,” said del Potro, who was given a wildcard into the event.
Del Potro said he was still feeling the effects of his efforts in Rio and almost gave the sport up during his injury struggles.
“It’s not easy after a big, big challenge like I did in Rio. But this tournament is very special for me. I’m trying to keep calm, to keep focused, and look forward to go far,” he said. “After the first surgery, the second one, and in the end the third one, it was really, really sad moments for me…nobody knows what should I have to fix my problem.
“The worst part of my life is totally in the past, and I’m living a good present and looking forward for a good future.”
Third seed and two-time slam winner Stan Wawrinka was also impressive with a 7-6 (7-4) 6-4 6-4 victory over Spaniard Fernando Verdasco at Arthur Ashe Stadium.
Wawrinka, winner of last year’s French Open and the 2014 Australian Open, had trailed Verdasco 3-2 in head-to-head action after falling to the Spaniard in straight sets in the first round this year at Queen’s Club.
“I’m really happy. I think it was a great match, especially for the first round,” Wawrinka said.
“You never expect to play your best game and (be) full of confidence, but I think the level was quite high.”
Wawrinka hit seven winners off his backhand among his 30 total for the match, blasted in seven aces and turned away all four break points held by the Spaniard.
Earlier, Kei Nishikori held off a fightback from Benjamin Becker and earned a 6-1 6-1 3-6 6-3 victory over the German veteran for a convincing start to his title bid.
The only top seed who exited on the men’s side of the draw was Belgian David Goffin.
