On paper, Andy Murray was strong favourite to book his ticket to the second round of the Australian Open.
But the British No.1 was in for a shock when unseeded Jo-Wilfried Tsonga, ranked 38th in the world prevailed in four sets.
The Frenchman went two sets up before Murray hit back with a whitewash in the third.
Tsonga, who had been struggling with a thigh injury, did enough to win the fourth-set tie-break to win 7-5 6-4 0-6 7-6 (7-5).
The feat was more remarkable considering he was playing in only his fifth Grand Slam. Tsonga would go on to cause more big high-profile casualties, defeating four seeded players, including Rafa Nadal, to reach the final, where he lost to Novak Djokovic.
