Andy Murray made a rare exit in the Australian Open first round after a subdued display against Argentine 30th seed Tomas Martin Etcheverry.
The 36-year-old Briton showed little emotion as he lost 6-4 6-2 6-2 on the second day of the Melbourne tournament.
Murray, a five-time finalist, failed to reach the second round for only the second time in his past 13 appearances.
After conceding 2024 could be his final season before retirement, the Scot has lost both of his matches this year.
Murray told BBC Sport in Brisbane he would think about ending his stellar career if he did not enjoy playing this year, having struggled for form in the closing stages of the 2023 season.
Since the start of the US Open in September, Murray has lost eight of his past 12 matches – including the past four.
Murray is the second Briton to fall in the singles at Melbourne Park, following Jodie Burrage’s defeat on Sunday.
Five more of the nation’s players – Emma Raducanu, Katie Boulter, Cameron Norrie, Dan Evans and Jack Draper – play their opening matches on Tuesday.
