Former world No.1 Andy Murray has shown Thanasi Kokkinakis who's boss, grinding out an gob-smacking five-set comeback victory to earn a spot in the Australian Open third round.
Winning the opening two sets and leading 5-2 in the third, Kokkinakis looked on track to complete a rare daily treble by Australian men, with Alexei Popyrin and Alex de Minaur earlier banking rousing second round wins.
