The first day of practice belonged to Mercedes as Lewis Hamilton joined Valtteri Bottas with a Friday P1 ahead of the Portuguese Grand Prix.

Hamilton topped the session with 1:19.837 which was 0.143s quicker than potential title rival Max Verstappen in Portimao. Valtteri Bottas, the FP1 session leader, completed the top three on Friday afternoon.

Elsewhere, there were encouraging signs for Alpine with both Fernando Alonso and Esteban Ocon inside the top 10 which also included the Ferraris of Carlos Sainz and Charles Leclerc, plus Daniel Ricciardo, Lance Stroll and Sergio Perez.

The afternoon practice session was delayed by 10 minutes as repair work was carried out on a loose drain cover, but it did not impact FP2 too much as no time was lost in the session overall.
