In the Australian Open, Roger Federer weathered a belated challenge from a gallant Andy Murray to win in four sets and set up a mouthwatering semi-final with great rival Rafael Nadal. The 17-time Grand Slam champion dug deep to fend off the scot in a final set of unrelenting tension, breaking Murray at 4-3 and sealing a classic contest with an ace. With the win, Federer notched his 11th successive semi-final at Melbourne Park as he bids for a record 18th Grand Slam. -- Mornings @ ANC, January 23, 2014
