Britain's former world number one Andy Murray produced a subdued display as he lost to Japan's Taro Daniel in the Australian Open second round.
Murray lost 6-4 6-4 6-4 to qualifier Daniel - ranked below him at 120 in the world - on John Cain Arena.
It was a far cry from his performance in Tuesday's win over Georgian 21st seed Nikoloz Basilashvili, with the gruelling opening win taking its toll.
Murray's defeat means Dan Evans is the final Briton left in the men's singles.
Murray had never previously lost a Grand Slam match to an opponent ranked as low as 28-year-old Daniel.
