World number one Andy Murray made a shock second-round exit at the BNP Paribas Open at Indian Wells, losing 6-4 7-6 (7-5) to qualifier Vasek Pospisil.
The Briton, who had a first-round bye, was sluggish throughout the match against the Canadian world number 129.
Murray, 29, was broken four times as he struggled with Pospisil's serve-and-volley style.
It was the first victory for Pospisil, 26, in five meetings with Murray.
Although he is a qualifier here, Pospisil has been ranked as high as 25th in the world and beat both Kyle Edmund and Dan Evans in Britain's Davis Cup victory over Canada in February.
