The flying Finn once again dominated, setting the pace on every single stage whilst still avoiding trouble in his Pirelli-shod machine.
He remained unchallenged by any of his opponents and topped the all-Ford Fiesta Rally3 leaderboard by 22min 27.1sec at close of play.
"We had a good day today and lead both groups, but there is still a long way to go tomorrow where anything can still happen. For now, we are feeling good,” said Pajari.
Zoltán László was Pajari’s nearest rival. He had 46.7 in hand over Enrico Brazzoli, who ended 2min 13.0sec in front of home hero Ivica Siladić.
Kenyan hopeful Mcrae Kimathi rounded off the top five, while William Creighton restarted to complete the leaderboard after crashing out on Friday.
