Amidst the most eventful day of this FIA World Rally Championship season thus far, which was marked by fluctuating conditions ranging from dry and dusty to wet and muddy, Rovanperä was one of few stars to enjoy a clean run.
He widened his lead to an impressive 2m 8.2s as drivers including Thierry Neuville, Elfyn Evans and Takamoto Katsuta faced significant setbacks.
Despite dominating every stage the previous day, Rovanperä adopted a more conservative approach on Saturday’s roads near Lake Elmenteita, located south of the rally’s Naivasha base.
Thierry Neuville emerged as Rovanperä’s closest threat, but his challenge was short-lived after his Hyundai i20 N encountered a fuel system issue during the afternoon’s first stage at Soysambu.
Rovanperä’s Saturday standing will earn him 18 points provided he completes Sunday’s stages.
Katsuta will receive 15 while Fourmaux, who ended 3m 13.3s off the lead, gets 13.
“The lead is now quite good,” said the two time world champion, “ so of course we took it carefully.
“It’s not so enjoyable when you have a big lead and in a stage like [Sleeping Warrior] you just go around every rock, it’s scary. Tomorrow is still a tough day and we will try to finish the job.
Fourmaux survived a front-left tyre delamination in the final stage and is now on track to secure his second top-three finish in consecutive rallies following his maiden podium in Sweden.
Sunday’s finale features three stages – each run twice – covering both sides of Lake Naivasha.
