Revelling in what he called "probably the best win in my career" on Sunday, the young Australian F1 superstar smiled about the moment on the Baku street circuit when he went for broke with his lap-20 pass to surprise Ferrari's race leader Charles Leclerc.
Piastri believed he had to make an attack swiftly in his McLaren after a pit stop - but Tom Stallard urged caution over the radio, wanting the 23-year-old to be easy on his new tyres.
"I saw half an opportunity after the pitstop and knew I had to try and take it," Piastri told reporters.
"I felt a bit sorry for my race engineer because I basically tried to do that in the earlier part of the race and completely cooked my tyres. So, he came on the radio and said, 'let's not do that again', basically."
"I completely ignored him the next lap - and sent it down the inside..."
The rest was monumental. Piastri cut inside a clearly shocked Leclerc, then avoided the wall when straightening up with the lead.
"Credit to Charles. He was incredibly fair. Maybe he thought I was going to sail on into the run-off, but I was pleasantly surprised I actually made the corner," smiled Piastri.
He never lost the advantage, defending with remarkable skill and poise from Leclerc's ever more desperate counter-attacks in the DRS range at that same turn for another 30 laps before the dirty air really did impact the Ferrari's rear tyres.
