MELBOURNE Jan 20 Andy Murray smashed a racket in a rare display of frustration after being taken to a fourth set before reaching the quarter-finals of the Australian Open with a 6-1 6-2 6-7 (6) 6-2 victory over lucky loser Stephane Robert on Monday.
After racing through the first two sets in just over an hour, Wimbledon champion Murray blew a couple of match points in the third and was dragged into a tiebreak by the 33-year-old Frenchman, who won it 8-6.
It was the first set fourth seed Murray had lost in the tournament but, after a change of shirt, he whipped through the fourth set in 28 minutes to seal a quarter-final date against either Roger Federer or Jo-Wilfried Tsonga.
Robert was the first lucky loser to reach the fourth round at Melbourne Park and had won just four main draw matches in 10 previous grand slam appearances. (Reporting by Nick Mulvenney,; Editing by Patrick Johnston)
