Mercedes’ Lewis Hamilton was in a league of his own in a second practice truncated by rain at the Monaco GP.
The world champion was 0.74 seconds faster than team-mate Nico Rosberg, who lagged behind Hamilton through both sessions on Thursday.
Ferrari drivers Sebastian Vettel and Kimi Raikkonen were third and fourth ahead of Red Bull’s Daniil Kvyat.
The Toro Rossos of Carlos Sainz and Max Verstappen were next from Fernando Alonso’s McLaren.
The drivers managed only 20 minutes or so of dry running before Manor’s Roberto Merhi lost control as he hit the brakes approaching the harbour-front chicane.
The car flicked one way and then the other, crashing into the barrier on the cliff side of the track nose-first and sliding to a halt in the run-off area at the chicane.
