Namibia, ranked 14th in the world, shocked Asia Cup champions Sri Lanka to win by 55 runs as the Men’s T20 World Cup started in spectacular fashion.
Namibia were 35-3 and 93-6, but Jan Frylinck and JJ Smit brilliantly hit 70 off 37 balls to drag them to 163-7.
Sri Lanka, who are eighth in the world, were all out for 108, to give Namibia just their second win over a Test side.
In the later game, the Netherlands chased 112 to beat the United Arab Emirates off the penultimate ball.
Namibia will now face the Netherlands on Tuesday (05:00 BST) and Sri Lanka will play the United Arab Emirates (09:00) in the next Group A games.
Scotland and Ireland’s campaigns will start on Monday, when they face the West Indies and Zimbabwe respectively in Group B.
The top two sides from each group will qualify for the Super 12s, which start on 22 October. The winner of Group A and runner-up from Group B will face England.
