Kirsty Gilmour was knocked out in the first round of the women's singles at badminton's All England Open Championships by Tai Tzu Ying.
The 21-year-old from Hamilton, ranked 27 in the world, lost 21-16 21-14 after a 34-minute contest against the seventh seed.
Gilmour led 6-2 in the first game but the 20-year-old Taipei player levelled at 6-6 before surging clear from 11-10.
The British number one also led in the second but was once again overtaken.
Commonwealth silver medallist Gilmour, who lost in three games against the same opponent in the 2013 World Championships, said: "She played better than the last time we met.
"I don't think I played badly. I felt OK with my game but I was not at my best."
Referring to a delay of almost three hours before she got on court, she added: "It's the same for both of us but it makes for a long day and it's hard to plan, you can't time your meals."
Gilmour will return home to train before heading out to play the Swiss Open on Tuesday.
