Eugene Mukangula and Shami Kibwana scored in either half to hand the Brookside sponsored outfit the sweet victory.
Mukangula scored in the opening minutes of the match before super-sub Shami made it 2-0 in the 79th minute to compound Tusker’s miseries being their second defeat.
Last weekend, they fell to newbies Nzoia Sugar by an historic 5-2 margin and their hopes of registering at least one point today (Sunday) were dented by the James Nandwa coached outfit.
