Mali scored within three minutes at the start of the match as the unfortunate Tapsoba turned the ball into his own net, and caught the Burkinabe cold again when they added a second two minutes after the break as Sinayoko netted his third goal of the tournament.
Burkina Faso pulled a goal back when Bertrand Traore slotted a penalty just before the hour-mark, but could not force an equaliser against a Mali side with a well-deserved reputation for a miserly defence, one of the reasons why they are among the tournament favourites.
Mali are seeking their first continental title and next face hosts Ivory Coast in a quarterfinal that will be played in Bouake on Saturday.
