Britain's Andy Murray missed three match points as he suffered a first-round defeat by Alex de Minaur at the China Open.
Murray led 5-2 in the third set and had two match points on De Minaur's serve, before the Australian broke back as Murray served for the match.
The Scot missed another match point in the tie-break as De Minaur prevailed.
It is the 36-year-old's fifth successive loss to De Minaur, who is number 12 in the world rankings.
Murray committed just 13 unforced errors compared with the 16 of De Minaur, who will play either Tommy Paul or second seed Daniil Medvedev in the second round.
