Scotland fell to their seventh successive defeat in the CB40 as Northamptonshire Steelbacks secured a nervous four-wicket win on Sunday.
Preston Mommsen smashed an unbeaten 81 off 72 balls as the Saltires recovered from a poor start to post 200 for five.
However, Chaminda Vaas starred with bat and ball for the home side.
The Sri Lankan took three wickets for 37 before making 68 off 88 balls as the Steelbacks reached their target with five deliveries to spare.
Scotland won the toss and chose to bat but they soon lost Callum MacLeod for a duck when he blasted Vaas straight to David Willey at point.
Josh Davey also went without scoring when he edged Vaas to David Sales at slip but Fraser Watts managed to make 29 before David Lucas' delivery clipped his off stump.
Richie Berrington missed an attempted reverse sweep and was pinned lbw by James Middlebrook for 28.
It wasn't until the 27th over that the Saltires reached 100 and the next wicket to fall was that of Luke Butterworth, bowled by Vaas for 20.
Mommsen went on to complete his half-century off 54 with a four clattered through extra cover as he tried to push his side towards a competitive total.
He and wicketkeeper Gregor Maiden did just that by adding 75 between them with the latter finishing on 32 not out.
Chasing 201, Vaas was given an early reprieve when Davey dropped a simple catch at fine leg off Butterworth in the second over.
Matthew Parker was the pick of the Scottish bowlers, claiming figures off three for 41.
The hosts made hard work of their task but 16 runs off the 37th over, bowled by Butterworth, swung the game back in Northamptonshire's favour and captain Andrew Hall and Middlebrook guided them home with scores of 21 and 31 not out, respectively.
