Mean Machine was promoted back to the Kenya Cup after beating Western Bulls 18-0 in the championship semis on Saturday at UoN grounds.
Machine return to the top flight rugby after one season in the Championship where they were relegated to in 2017.
The University of Nairobi side ran in two tries, two penalties and one conversion as Bulls left with nothing.
