Namibia 115 for 6 (Smit 32*, Williams 23, Leask 2-12) beat Scotland 109 for 8 (Leask 44, Greaves 25, Trumpelmann 3-17, Frylinck 2-10) by four wickets
Abu Dhabi: Namibia held their nerve to beat Scotland by four wickets in the final over of a tense Super 12s match at the ICC Men's T20 World Cup.
Namibia, who like Scotland are competing at this stage for the first time, stuttered in their chase of 110 but sneaked home with five balls to spare in Abu Dhabi.
They were 67-4 at one stage and their scoring ground to a halt as two more wickets fell late on, but JJ Smit hit an unbeaten 32 from 23 balls to seal victory with a six over point.
Scotland were left ruing a horror start with the bat before they limped to 109-8, largely thanks to Michael Leask's 27-ball 44.
George Munsey was bowled by the first ball of the match and Scotland were 2-3 when Ruben Trumpelmann took two more wickets in the opening over.
Namibia came into the game as slight underdogs, ranked 16th in the world to Scotland's 12th, but, despite their wobble with the bat, ended the match posing for photographs after another landmark victory.
When their captain Gerhard Erasmus was bowled by left-arm spinner Leask and opener Craig Williams was stumped down the leg side off Mark Watt in the 12th and 13th overs respectively, there was an outside chance of a Scotland victory.
But Smit remained calm, even when David Wiese fell for 16 with eight still needed.
In truth, Namibia won the game through Trumpelmann's opening burst.
The fiery left-arm seamer found swing and utilised it well. After Munsey played on, Calum MacLeod edged behind and Richie Berrington - Scotland's stand-in captain with Kyle Coetzer sidelined by a finger injury - was lbw to a ball that nipped back.
Leask's hard-hitting innings, which included four fours and two leg-side sixes, rescued Scotland from a repeat of their 60 all out against Afghanistan.
He also took 2-12. Had Scotland mustered another 20 runs, their bowling display may have been enough.
