| The Spaniard, champion here in 2009, needed to be at his 
				resilient best to come out on top after more than four hours of 
				top quality shot-making and thrilling rallies which earned both 
				players a huge ovation from the Rod Laver Arena crowd.
 The 19-year-old showed in spades why many consider him a future 
				grand slam champion but was just unable to stay with Nadal in a 
				gripping deciding set, which the 30-year-old sealed when the 
				24th seed netted a forehand.
 
 Returning to Melbourne Park as ninth seed after curtailing his 
				2016 season because of injury, Nadal will next face Gael Monfils 
				of France or another German in Philipp Kohlschreiber as he bids 
				for a 15th grand slam title.
