Rob Taylor made his full international debut but Scotland lost a second consecutive World Cricket League Championship game against Afghanistan.
The team suffered a seven-wicket defeat in the first game on Wednesday and again came up short in Sharjah, this time by a five-wicket margin with eight balls to go.
Scotland were very well-placed on 144-1 in the 32nd over following a great 134-run stand between Kyle Coetzer and Josh Davey.
However, Davey fell for 64 and although Coetzer almost batted through the innings for a superb 133 from 136 deliveries, Scotland were not able to fully capitalise on their fine start and had to settle for 259-9.
The Northants batsman was the 7th wicket to depart in the 47th over, while Taylor went for nine in the penultimate over.
The score was still a competitive one but Afghanistan got off to a good opening thanks largely to Mohammad Shahzad (48 off 34 balls). Taylor checked progress as he had wicket-keeper Shahzad caught by Preston Mommsen, who played some games for Leicestershire last season.
Taylor finished with good figures of 9-1-47-1 from his first bowl at international level but there were good contributions from all of the Afghanistan batsmen and they emerged victorious.
It means Afghanistan join Scotland in second on 11 points following their two wins while Netherlands and United Arab Emirates are just a point behind with two games in hand. The top two teams will qualify for the World Cup, with the other nations getting a second chance to qualify in a second tournament alongside the third and fourth sides in World Cricket League Division Two.
Leicestershire’s Niall O’Brien is part of an Ireland squad who top the group and they face UAE in two 50-over games later this month. The Netherlands take on Namibia in two games in April.
