Oscar Piastri led Lando Norris to a McLaren one-two in Friday practice at the Emilia-Romagna Grand Prix.
The Australian, leading the world championship from Norris by 16 points after four wins in the first six races, headed Norris in both sessions, and ended the day 0.025 seconds quicker.
Alpine's Pierre Gasly was a surprise third quickest, ahead of the Mercedes of George Russell, Red Bull's Max Verstappen and Ferrari's Charles Leclerc.
Lewis Hamilton, struggling with braking feel, was 11th fastest in the second Ferrari.
