Namibia coach Andy Waller said his side's convincing seven wicket win over Scotland was down to what the players had learnt from their previous matches against India and Sri Lanka.

The Africans had lost both of those matches convincingly but on Thursday they bowled the Scots out for just 156 before knocking off the runs in just 36.3 overs for the loss of only three wickets.

Waller said that performance was due in large measure to his players watching the way the opposition played in their previous two outings and carrying that forward into their latest match.

"I thought we were brilliant in all three departments today, we batted brilliantly, fielded exceptionally and our bowling was great," he said.

"I put a lot of that down to what the players saw during the previous two matches because they saw how the opposition went about things and adopted some of those techniques.

"Today we built partnerships, bowled with discipline, ran well between the wickets and they saw all of that against us in those first two games. I am sure that helped."

Namibia were certainly disciplined in every aspect of their play but they were also helped on their way by another disappointing batting display from Scotland.

For the third time in as many matches their top order failed and it meant once again super sub Scott MacLennan was called into action at the expense of a bowler.

Only captain Kasaim Farid, who made 76 against the hosts on Sunday, topped 40, making 46 from 73 balls with five fours.

Apart from Farid, the only other batsmen to make it to 20 for Scotland were Richard Berrington (26) and Aamir Mehmood (20) as the Scots, already dismissed for 186 against Sri Lanka and 112 by India, were bowled out in 48 overs by their fellow Associate side.

Nicolaas Scholtz was Scotland's main tormentor as he captured 4-25 with his left-arm spin while opening bowler Floris Marx took 2-19.

The Namibian bowlers conceded only 11 fours through the entire Scotland innings but the only blot on their copybook was the 21 wides they gave away, a significant number in Scotland's relatively meager total.

The other wicket-takers for Namibia were medium-pacer Henno Prinsloo, who took 1-13 in a miserly 10 overs, Morne Engelbrecht (1-34) and Marc Olivier, who captured 1-44 from seven overs in his first outing of the tournament.

"We shot ourselves in the foot with our batting again," said Farid afterwards.

"If we had the answer to why we have failed then we would solve it. I guess it is just one of those things."

Namibia were never troubled in pursuit of their modest target and with Dawid Botha, their leading batsman, making a solid, unbeaten 55 from just 70 balls and including six fours they won comfortably.

It sends Namibia into the Plate competition with the momentum of a victory under their belt and now they will face the USA next Tuesday.

"We have that momentum and now we have belief and while we do not expect the USA to be a walk-over we will give them a real run for their money," said Waller.

As for Scotland, Farid said they will be clinging to the memory that they bounced back from similar disappointments two years in Bangladesh when, having been mauled in the group stages, they reached the Plate semi-finals.

"There is nothing stopping us doing the same again as long as we all go out and express ourselves," he said.

"Everyone is in the team for a reason and can do a job and it is just a case of the boys finding some confidence," he added.

Scotland will face the losers of Friday's match between South Africa and the West Indies in next Tuesday's Plate quarter-final.
