Home favorite Oscar PiaTri expressed Mercedes’ George Russell to finish the fastest in the final exercise for Australian Grand Prix.
When the teams began to show their full potential with a series of low-fuel runs, McLaren’s PiaTri Russell’s challenge saw with just 0.039 seconds.
World Champion Max Verstappen took third place, 0.081 sec of the pace, and one place ahead of Ferrari’s Charles Lecler.
Leclerc was the fastest in the Albert Park in Melbourne on Friday, but said the handling of his Ferrari affects his confidence in the closure before he qualified.
Leclerc drew Piactri with 0.267 seconds, with Lewis Hamilton eighth in the other Ferrari, almost half a second. Lando Norris finished 10th, nearly seven tenths behind, after not setting up a representative shot.
British teenager Ollie Bearman was forced to miss the second session on Friday with damage his rabbit sustained after an accident in the weekend opening.
On Saturday, the 19-year-old was the first driver out of the pits when he tried to make lost time.
However, Bearman could not complete one flying shot after losing control of his rabbit and addressing in the gravel.
Bearman was left in his cabin and shaken his head while the session was red flag.
Although Bearman – one of the six rookies on the grid this season – has avoided any damage, he will be under intense investigation later on Saturday and hardly qualify any running under his belt.
Qualification, which determines the timetable for Sunday’s curtain hoger, will take place at 16:00 local time (05:00 GMT).
