Roger Federer vs Stan Wawrinka LIVE: Aus Open 2017, semi-final – Wawrinka wins next two sets after losing first two

Melbourne: 17-time Grand Slam champion Roger Federer is up against compatriot Stanislas Wawrinka in men's singles semi-final of Australian Open 2017. Roger Federer will attempt to reach his first Grand Slam final since 2015 at the Australian Open on Thursday, while Serena and Venus Williams are both gunning for the women`s title match.

Federer`s major-winning days seemed over after first Novak Djokovic and then Andy Murray emerged at the top of the pecking order, but the Swiss legend, 35, has surprised everyone with his run to the semis.

With Djokovic and Murray long gone, fellow Swiss Stan Wawrinka is blocking Federer`s path to Sunday`s title match, where he intends to become the oldest major finalist since a 39-year-old Ken Rosewall at the 1974 US Open.

Federer, who last contested a major final at the 2015 US Open, has a 5-1 record against Wawrinka at Grand Slam tournaments but he is yet to lose in 13 meetings on hard courts, conceding only four sets.

However, the hard-hitting Wawrinka -- the Swiss number one, with Federer`s ranking at 17 after six months off with injury -- will not roll over for his illustrious countryman as he looks for his fourth major title.

"For sure, against Roger, it`s always special because he`s so good. He`s the best player of all time. He has an answer for everything," said Wawrinka, 31.

"But I have managed to beat him in a Grand Slam, so we`ll see. Most important is that I step on the court and I play my best tennis."Despite Wawrinka`s breakthrough 2014 Grand Slam title in Melbourne, Federer will be the crowd`s sentimental favourite as he presses his claims for a record-extending 18th major crown.

"If someone would have told me I`d play in the semis against Stan, never would I have called that one for me. For Stan, yes, but not for me," Federer said.

Federer also has the prize of a potential final against his old rival Rafael Nadal, who will play Bulgaria`s Grigor Dimitrov in the other men`s semi-final on Friday.
