Somerset defeated Scotland by 53 runs under the Duckworth-Lewis system after rain affected their Clydesdale Bank 40 fixture.
It was Somerset's sixth CB40 victory in a row and maintains their hopes of a semi-final berth which seemed unlikely after they opened their campaign with four straight defeats followed by a no result.
After winning the toss, Scotland decided to bat first but were bowled out for 163 and were indebted to Preston Mommsen's 67 to even take them that far.
Steve Kirby finished with 2- 22 and Robert Mutch began his Somerset career with 2-46.
But rain ended the match after 22.4 overs of the Somerset reply, with their total of 133-3, built around Arul Suppiah's half-century, far in excess of the revised target of 81.
The visitors lost opener Peter Trego for 15 and Chris Jones was next to fall for 24, but by that stage Somerset were 90-2 after a stand of 71 between Jones and Suppiah.
The latter made 56 from just 45 balls, with seven fours and a six, to steer his side towards the victory target before his was the last Somerset wicket to fall when he was bowled by Majid Haq.
Jos Buttler hit five fours and a six to score a rapid 29 not out while James Hildreth was also still at the crease on nine not out when the heavens opened and Somerset were declared the victors.
