Piastri delivered one of the most impressive debut seasons in recent years, taking two podiums and a pole-to-flag win in Qatar's sprint as his McLaren team hit a purple patch of form after the summer break.
While still some way off the race performances of his more experienced team-mate Lando Norris, who grabbed six podiums and scored over twice the number of points, the unflappable young Australian impressed with his maturity in his first year in F1.
McLaren team principal Stella was delighted with Piastri's performances and demeanour across the whole season but singled out his maiden podium at Suzuka as the main highlight. In Japan, Piastri outqualified Norris by a tenth to take second on the grid behind poleman Max Verstappen.
After ceding second to Norris at the start, Piastri drove a controlled race to third, comfortably keeping Ferrari's Charles Leclerc at arms’ length.
According to Stella, the fact that Piastri had never seen the challenging Suzuka before made his maiden podium even more impressive.
"On a track like Suzuka he put it in P2 on the grid, we really need to reflect for a second on the extent of this result," Stella pointed out. "A track like Suzuka – not only is it high-speed, but it’s a very narrow track, it’s a very unforgiving track as soon as you go too wide because you have the gravel in some places.
"In terms of speed, in terms of capacity to learn very rapidly, in terms of collaborating with his engineers and extracting the information that he needs to grow so rapidly, in terms of his own awareness of where he is in the various stages to go from: ‘I know nothing about this track, first time in a Formula 1 car' to being P2 on the grid.
