Charles Leclerc led a surprise Ferrari one-two in Thursday's practice at the Monaco Grand Prix.
Leclerc topped the second session, 0.112 seconds clear of Carlos Sainz despite missing virtually the entire first session with a gearbox problem.
Sainz was 0.278 seconds quicker than Mercedes' Lewis Hamilton, who was 0.007secs quicker than title rival Max Verstappen of Red Bull.
Mercedes' Valtteri Bottas was fifth, from McLaren's Lando Norris.
Leclerc's performance on his home track was especially impressive, as drivers say that track time is crucial in Monaco to allow them to build up the necessary confidence to push to the limit between the barriers.
But Ferrari looked competitive all day. Sainz was continually up at the sharp end through the first session, ending it second fastest to Red Bull's Sergio Perez.
