Muscat: Toby Bailey suffered a debut defeat as interim Scotland head coach in the opening T20 Quadrangular Series match against the Netherlands in Oman.
The Dutch secured a seven-wicket win with one ball to spare.
Calum MacLeod (53) was Scotland's top scorer as they hit 153 for seven.
Dutch openers Stephan Myburgh and Tobias Visee (71) combined to make 100, but the run rate slowed and victory came with a wayward Ruaidhri Smith delivery from the penultimate ball.
Scotland opener George Munsey hit 32, but they were on the back foot after captain Kyle Coetzer fell for one and Matt Cross for five at the Al Amerat Stadium.
Bailey's side next face Ireland on Friday before Sunday's final game against the hosts.
Earlier, Scotland raced out of the blocks to be 33 in the first two overs. Munsey was the one offering the fireworks, his 32 runs off 10 balls by then including five fours and two sixes.
The Netherlands wrested back the initiative to reduce them to 44/4, Timm van der Gugten picking up two of those wickets, before a vital half-century from Calum MacLeod, playing his first international innings since being crowned ICC Men's Associate Player of the Year 2018, revitalised the Scotland innings.
