In the first quarterfinal of Sudan, who ended Harambee Stars interest in the tournament dimmed the determined run of surprise package Burundi by handing them a 2-0 defeat.
The team, full of confidence befitting the only CECAFA nation strolled through their opponents emphatically to book their place in the last four.
On account of earlier good performances Burundi were deemed by some as a possible banana skin for Sudan but their experienced players led by example, going about the business of scuttling all of their strategies.
Amir Abdelnabi and Musa Mohammed scored on either side of half time.
After 70 minutes, the Sudanese were down to 10 men, following the dismissal of Nagmeldin Abdalla, but they had already imposed themselves on the match and there was no comeback for Burundi.
But Burundi blew the chance to hang on to hope by missing a penalty kick.
In the second match at the National Stadium, Rwanda left it late to see off the determined challenge of islanders Zanzibar.
Jean Baptiste Mugiraneza opened the scoring in the 39th before Abulrahaman Mohammed levelled the scores just after the break.
Zanzibar were on course of serving a huge upset until the boot of Meddie Kagere came to the rescue in the 88th when he delivered a scorching winner that finally neutered the sting from The Wasps.
The Amavubi Stars who went through their group with a perfect winning record thus continued underlining their status as one of the favourites for the title.
