The former champions scored twice in the first half to claim their first points of the new league campaign
The 2008 FKF-Premier League champions Mathare United have recorded their first win this season after defeating their hosts Zoo FC 2-0 at Kasarani Stadium on Monday.
Daniel Otieno and John Mwangi scored the goals that handed the Slum Boys maximum points.
After back-to-back defeats against Sofapaka and Gor Mahia, the Slum Boys hosted the Kericho-based team hoping to collect their first win this season.
They were not going to get it easy against their visitors who had registered two 1-1 draws against Bandari and Posta Rangers in their last matches.
