The Cricket Cranes were handed a seven-wicket loss by their hosts Namibia at the Wanderers Park in Windhoek.
Uganda handed Ronak Patel and Cosmas Kyewuta their T20 international debuts with Jonathan Ssebanja, Trevor Bukenya and Saud Islam sitting out the first game.
Captain Arnold Otwani won the toss and chose to bat first. Roger Mukasa and Arnold Otwani made a strong stand of 37 in 5 overs but once they both departed the run scoring became laboured.
Hamu Kayondo (28) and Ronak Patel (35) were very cautious in their approach with Uganda bringing up its 100 in 15 overs. Riazat Ali Shah (23) had a brief cameo that added some impetuous to the innings as the Cricket Cranes closed on 134/5 in 20 overs.
In the chase, the hosts got off to a flyer scoring freely despite losing two early wickets. Eagles captain Gerald Erasmus (62 not out) was the destroyer in chief taking his chances after being put down on 4 and 27.
In the end, it was an easy win for the hosts but lessons for the Cricket Cranes that will need to be fixed before Monday when they meet again for two T20 games.
