Mathare United suffered a 2-0 defeat in the hands of Sony Sugar in the Kenyan Premier League match played on Saturday at Camp Toyoyo.
Tobias Onyango was the tormentor in chief, scoring the two goals that helped his team move away from the relegation zone.
Coach Francis Kimanzi admitted that it became hard to make a comeback after conceding early goals.
"It is a disappointing loss for us, once we were down it was difficult to come back, we had a slow start and it affected us and ended up losing the match.
"We were unlucky as well, chances were there but we did not take them.
"It has already happened and now we should go back, rectify our mistakes and ready ourselves for the next match."
The 'Slum Boys' are currently sixth on the log with thirty-five points.
