A stunning opening burst from seamer Ruben Trumpelmann and an unbeaten 32 by JJ Smit down the order helped Namibia secure a nervy four-wicket win over Scotland in their Group I encounter in Abu Dhabi on Wednesday.
Set a modest 110 for victory, Namibia made heavy weather of the chase, losing wickets at key moments on a tricky pitch before Smit and David Wiese (16) did just enough to get them over the line with five balls to spare.
It was Scotland's second straight defeat following their crushing loss to Afghanistan on Monday, effectively ending their hopes of making the semi-finals with New Zealand, India and Pakistan still to come.
Scotland could never really recover after left-arm quick Trumpelmann (3-17) ripped their top-order with three wickets in the first over of the innings. Wiese (1-22) later removed Craig Wallace (4) as Scotland ended the powerplay on 22-4.
Michael Leask (44) briefly threatened to salvage the innings but had his stumps rattled by Smit (1-20) just as he was preparing to mount a late assault before Chris Greaves (25) made sure that Scotland crossed the 100-run mark, finishing on 109-8.
