After having already been the fastest in the second session held on Friday afternoon, the Scuderia driver lowered his time to 1 minute, 11 seconds and 632 thousandths.
Leclerc preceded Britain’s George Russell’s Mercedes by just 66 thousandths and Dutchman Verstappen’s Red Bull by 161.
Third best team this year, Mercedes placed Lewis Hamilton in fifth place in this third test session, behind the other Ferrari, the one driven by Carlos Sainz (4th), but ahead of Sergio Pérez’s Red Bull, sixth.
The qualifications now await the pilots, at 3:00 p.m. local time (1:00 p.m. GMT).
In his country, “Mad Max” had taken pole last year, in the return of the Dutch GP to the F1 calendar, a performance that he hopes to renew this year, before his “Orange army”, who wants to support from the stands to the world champion.
Before this fifteenth race, of 22, at the Zandvoort track, Verstappen has a 93-point advantage over Pérez and 98 over Leclerc.
The two Mercedes had been the fastest in the first session on Friday, before being dethroned in the afternoon by the two Ferraris.
