Fernando Alonso added fuel to the fire of Aston Martin hopes by finishing fastest in Bahrain Grand Prix second practice.
The two-time champion is making his debut for the Silverstone-based outfit this weekend and having finished second in FP1 finished 0.169secs faster than Red Bull's Max Verstappen after posting a one minute, 30.907s.
Crucially, the strong pace came as darkness fell and conditions became representative for qualifying and the race across the weekend.
Sergio Perez was only 0.002s adrift of his team-mate with Verstappen complaining of his RB19 'jumping a lot'.
Ferrari looks off the pace if times are to be believed, with Charles Leclerc fourth, almost half a second slower than Alonso.
The surprise of the session was Nico Hulkenberg, who matched Leclerc's pace to finish fifth ahead of Lance Stroll, who showed impressive performance considering his lack of running time.
