SIR Andy Murray has fought back after an early scare to claim a straight-sets victory over American Sam Querrey at the Australian Open.
The world No.1 was caught by surprise by his Californian opponent, who broke his serve early in the piece, but Murray quickly proved why he's the best in the world and blasted his way back into the match with signature class.
It was the 29-year-old's 48th victory at the Australian Open, four away from a possible maiden title at Melbourne after losing an astonishing five finals.
Meanwhile, crowd favourite Jo-Wilfred Tsonga took home a win against American Jack Sock after dropping the third set.
Andreas Seppi, who took advantage of an imploding Nick Kyrgios in the second round, has also won his way into the fourth round by defeating Belgian Steve Darcis.
The Italian lost the first set but ended up victorious 4-6 6-4 7-6 (7-1) 7-6 (7-2) to equal his best performance at the Australian Open.
Seppi will face fourth seed Stan Wawrinka, who beat 29th seed Viktor Troicki in four sets.
