Charles Leclerc set the pace around the Baku City Circuit in second practice for the Azerbaijan Grand Prix, heading team-mate Sebastian Vettel in a Ferrari one-two.
FP2 went ahead as planned following fears the session could be postponed due to a bizarre incident during the morning’s practice segment.
Williams driver George Russell ran over a loose manhole cover on the run towards Turn 3 that caused substantial damage to his FW42’s chassis.
The Briton was forced to sit out of the reminder of practice on Friday, regulations permit a driver cannot take part in another session if changes are to made to the chassis.
The session was duly red flagged before further inspection into the cause of the incident led to the cancellation of FP1, allowing track inspectors to perform safety checks around the circuit.
Leclerc’s 1:42.872 topped the timesheets, three-tenths quicker than Vettel’s personal best on the soft compound tyre.
Championship leader Lewis Hamilton was the quickest non-Ferrari runner, the Briton’s best time was sixth-tenths off Leclerc’s benchmark, with the second Mercedes of Valtteri Bottas classified in fifth.
Max Verstappen was once again the leading Red Bull as he split both Mercedes to finish the session in fourth, just under a second off the leading pace.
Daniil Kvyat was hindered by a mechanical issue that halted his running in the first half of FP2, but went on to set the sixth-fastest time once his issue was fixed.
However, the Russian pushed too hard on a flying lap that caused him to lose the rear of his Toro Rosso, sending him into the outer wall at Turn 7 that ripped off his left-front tyre.
Both McLaren’s made their way into the top 10 with Carlos Sainz seventh and Lando Norris tenth, the Woking-based outfit is looking to score points after both cars were involved in a first-lap crash in China.
Racing Point’s Lance Stroll was the second driver to find the barriers in second practice, the Canadian’s session ended early when he overcorrected a slide that sent his car into the wall at Turn 2.
