Injury forces Rafael Nadal out of Australian Open quarter-final

Top seed Rafael Nadal has retired hurt in his Australian Open quarter-final against Marin Cilic, who led 2-0 in the deciding set.

The world number one looked to be on his way to yet another grand slam semi-final when he moved two sets to one in front but he called for the trainer after going a break down in the fourth set.

Nadal took a medical time-out but was clearly hampered in his movement and, after limping around the court for two games at the start of the fifth set, he headed to the net to shake hands.

The 3-6 6-3 6-7 (5/7) 6-2 2-0 victory gave Cilic a first victory over Nadal since 2009 and sent him through to his first Australian Open semi-final since defeat by Andy Murray in 2010.

Cilic will meet Britain’s Kyle Edmund in Thursday’s semi-final.
