Championship leader Oscar Piastri and his McLaren teammate Lando Norris managed only the fifth and sixth quickest times in Friday's first practice session behind the other Ferrari of Lewis Hamilton. Verstappen trails Australian Piastri by 69 points in the drivers' standings and will be looking to cut further into that deficit this weekend. Mercedes drivers George Russell and Kimi Antonelli managed only the 11th and 14th fastest times but, like Sainz, elected not to run on the quicker soft tyres.
