Piastri challenged Briton Norris Hard during the first visit after spending Charles Leclerc de Ferrari, who had divided the McLarens in qualification, in the first corner.
Norris made mistakes at his new and 10 turns at the end of the 10th round, which gave Piastri the opportunity to run on him in the next round.
PiaStri briefly took the lead on the Tour three, only so that Norris returns to the next corner.
And Piastri flirted with a disaster when he made a late dive into the interior of the four round, locking his brakes and barely avoiding knocking on the back of Norris’s car.
Norris made his first stop at the end of this Tour. PiaStri waited three other laps before doing his own, and Norris seemed to be in control in the middle of the passage.
But after their last judgments, that they made one after the others with 17 and 16 laps to do, Piastri started to close.
Released from his stop at four seconds behind, Piastri was in the two seconds of Norris with 10 laps to do, and Norris went on the radio to tell his engineer Will Joseph that he “needed a rhythm – please help”.
Piastri was afraid with six laps to do when he was bathed on the grass on the right between three and four years by Franco Colapinto d’Alpine, but was able to continue and maintain the pressure on Norris. Argentinian received a five -second penalty for the incident.
But Norris, despite some damage on her front wing, managed to stabilize the gap and keep the checkered flag for an essential victory, two weeks after finishing his own Canadian Grand Prix by falling on the back of his teammate.
Piastri said: “I tried my best, but could have done a better job when I had a momently advance, but it was a good battle, a little at the limit.
