Scotland fell to a heavy 49-run defeat by Namibia at the World Twenty20 qualifier event in Abu Dhabi.
Set a target of 193 runs in the Group B fixture, Scotland could only manage 143 for eight in their 20 overs.
Scotland got off to a dream start when Gerrie Snyman was bowled by Safyaan Sharif in the second over for the loss of only six runs.
However, Louis van der Westhuizen took control of the innings, hitting an unbeaten 106 off 54 balls.
Van der Westhuizen's impressive knock included eight fours and eight sixes as Namibia followed up their surprise win over Ireland in style, losing just three wickets.
Scotland failed to fight back with the bat, with only opener Richie Berrington managing over 30 runs before being trapped lbw.
Van der Westhuizen had a good day with the ball as well, claiming two wickets, including that of Berrington, for 16 runs.
Majid Haq's 27 not out from number seven brought things closer to respectability but it was a day to forget for the Scots.
The Scots had got off to a winning start in Dubai, beating Kenya by 14 runs on Tuesday.
Uganda, who have won their opening two fixtures, are Scotland's next opponents in Group B on Thursday.
The tournament is staged across the United Arab Emirates from 13-24 March, with two of the 16 nations progressing to the finals in Sri Lanka later this year.
