Taking the lead late on Friday when fellow FIA Junior WRC regular Hamza Anwar was forced to retire after picking up three punctures on the day's final stage, Dominguez was unrivalled on Saturday as all other competitors in the all-Ford Fiesta Rally3 class required assistance to get back to the Naivasha service park.
Anwar's troubles from Friday afternoon continued into Saturday morning when the Kenyan hopeful came to an abrupt halt following a water splash on the day's first stage.
Next to falter was Jason Bailey. After winning the opening stage of the day and sitting a comfortable second overall, the Canadian hit a compression and damaged his engine's oil sump, elevating Jeremiah Wahome into second at the end of the loop.
Further back in the field, there were also problems for last year's Junior WRC participant McRae Kimathi, whose rally ended with a broken steering arm.
