			 Moved from the Arthur Ashe Stadium court to Louis Armstrong to bring 
			Federer's match forward, Wawrinka appeared untroubled by the change 
			of venue, needing just an hour and 47 minutes to repel big-hitting 
			South African Kevin Anderson 6-4 6-4 6-0. 
			 
			Second seed Federer turned in an equally economical effort, brushing 
			aside Frenchman Richard Gasquet 6-3 6-3 6-1 in a tidy 87 minutes to 
			set up an all-Swiss semi-final on Friday. 
			 
			The other side of the draw features a battle of the big men, with 
			top seed Novak Djokovic taking on defending champion Marin Cilic. 
			 
			"Emotionally it's not so hard for me," said Federer, who holds a 
			commanding 16-3 advantage over his Davis Cup team mate and reigning 
			French Open champion. 
			 
			"But subconsciously, you know he knows what your preferences are, 
			where you like to go and where you're probably going to go," he 
			added 
			  
			"That's the weird part. I feel we meet each other somewhere in our 
			minds before the point is being played out." 
			 
			Federer and Gasquet are both armed with elegant one-handed backhands 
			but apart from that aesthetically pleasing stroke, there were very 
			few similarities in their lopsided contest. 
			 
			The 17-time grand slam winner could hardly miss and Gasquet all too 
			often played the role of innocent bystander as the Swiss maestro 
			uncorked 50 winners to a mere eight from the 12th seeded Frenchman. 
			 
			'I'M READY' 
			 
			Anderson, meanwhile, lacked the energy he displayed in a fourth 
			round upset of third seed Andy Murray, allowing Wawrinka to dictate 
			play for large stretches of the match. 
			 
			The South African, who leans heavily on his serve, could manage just 
			nine aces and one break point the entire match, which he was unable 
			to convert. 
			 
			"I've improved a lot over the past three years and feel much closer 
			to his level now," Wawrinka said of his compatriot.

			"He is playing really well here so I will need to be at my best. 
			He's had some amazing matches and I know it will be a big challenge 
			but I think I'm ready." 
			 
			Halep moved closer to a first grand slam singles title after edging 
			Victoria Azarenka 6-3 4-6 6-4 to set up a meeting with Flavia 
			Pennetta, who toppled Czech fifth seed Petra Kvitova 4-6 6-4 6-2 to 
			join compatriot Roberta Vinci in the last four. 
			 
			Defying the odds, rankings and age, 33-year-old Pennetta and 
			32-year-old Vinci etched their names in history by becoming the 
			first two Italian women to reach the semi-finals of the same grand 
			slam in the Open Era. 
			 
			With 33-year-old Serena Williams also in the last four, 23-year-old 
			Halep will be conceding almost a decade of experience to her 
			remaining challengers. 
			 
			"Of course we are a little bit old for the age of tennis right now," 
			Pennetta admitted. "But we are here and still fighting." 
			 
			However, the dream of an All-Italian final will require some special 
			magic, particularly from Vinci, who has the daunting task of facing 
			three-times defending U.S. Open champion and world number one 
			Williams.
