Josh Davey shrugged off his latest record-breaking feat for Scotland and insisted success was laid on a plate.

The all-rounder not only produced the best ever ODI bowling display by a non-Test player, he also became the first Scot to hit a half century and claim a haul of at least five wickets on the big stage.

But a modest Davey, who already held the national ODI bowling record, played down his feat by declaring: "Conditions were all in my favour when Afghanistan were batting. It turned out to be one of these days for me when everything just went right.

"They don't come around all that often, but it was just a case of keeping it simple by putting the ball in the right place and letting the wicket do the work."

Aberdonian Davey, who signed for Somerset last year, added: "The dew had come down when the floodlights came on and that definitely played into my hands.

"It was good to break my own Scottish record and when I heard it was also the best bowling performance by an Associate Nation player, it was just the icing on the cake."

Scotland's remarkable win rekindled their Tri-Series hopes and provided a massive boost ahead of next month's World Cup.

The Scots produced another below-par batting performance under the lights at the Zayed Stadium, Abu Dhabi. However, their pace bowlers hit form in sensational fashion to end a three-game losing streak at the hands of the Afghans.

Davey was the hero with 6-28 - his remarkable performance upstaged Majid Haq, who became Scotland's most capped player on the day - and he had brilliant backing from Iain Wardlaw, who took 4-22 as Afghanistan were routed for just 63, giving the Scots an incredible 150-run win.

Chasing just 214 for victory, Afghanistan's openers had come flying out the blocks to race to 38-0 after just six overs. But Davey, whose half-ton had earlier helped Richie Berrington rescue the Scottish innings, turned the tables in dramatic fashion.

The Somerset player twice took two wickets in an over and went on to eclipse his own record of 5-9 - also against Afghanistan. With three lbws and two clean-bowleds in his haul, he was rewarded for bowling straight and fast, a vast improvement from the opening two matches of this competition.

In the end it hardly mattered that Scotland's top order once again failed to get their side off to a solid start after Preston Mommsen had won the toss and elected to bat first.

Kyle Coetzer and Calum MacLeod briefly flattered to deceive with the former stroking three early boundaries in an opening stand of 17. However, when the Northants batsman edged Aftab Alam to the keeper to depart for 16, it sparked a mini-exodus that saw wickets fall at an alarming rate.

Freddie Coleman, making his first appearance of the tournament, had come and gone in the blink of an eye while MacLeod, having avoided a hat-trick of ducks, departed for just five to leave the Scots teetering on 25-3.

A stand of 36 between Matt Machan and Mommsen hauled Scotland out of the mire but they quickly found themselves back in it as another procession ensued. Machan, who had made 86 against Ireland on Monday, was unable to repeat such extravagance and was trapped in front for 13 by Mirwais Ashraf before the skipper fell three overs later.

Mommsen had stroked five boundaries in an enterprising 31 but, in attempting to repeat a fine leg-glance which had earlier brought four runs, misjudged the line and was bowled by Samiullah Shenwari. The same bowler accounted for Matthew Cross, who had hit three boundaries in his 23 before holing out to leave the Scots with a sink-or-swim poser on 108-6.

Happily Berrington and Davey chose the latter option with a 99-run partnership which not only saw the innings stretched to its 50-over limit but also proved to be of match-winning proportions. Davey even managed to score his 53 at faster than a run-a-ball and his five boundaries included a cheeky scoop over the keeper's head to leave Alam nursing a grievance since his previous delivery had seen the batsman dropped in the covers.

Alam was soon appeased with his third wicket as Berrington's 84-ball knock came to an end when he was caught on the boundary while attempting to add a maximum to his 62 runs.
