Ferrari's Charles Leclerc was fastest in a bizarrely interrupted final morning of Formula One's preseason test in Bahrain on Friday before handing over to teammate Lewis Hamilton for the afternoon.
Mercedes' 18-year-old Italian rookie Andrea Kimi Antonelli was second on the timesheets, 0.077 slower than Leclerc's best lap of 1:30.811 seconds, with McLaren's Lando Norris third.
Four-time world champion Max Verstappen was fourth, 0.398 off the pace, for Red Bull.
The four-hour session at the Sakhir circuit was briefly halted with 40 minutes remaining when a pane of glass, from the starter's box where the chequered flag is also waved, shattered and fell on the track.
The engine cover of British rookie Oliver Bearman's Haas also fell off during the session.
“It's hard to know what fuel loads everyone is running as we're all doing our own different programmes, so you have to take everything with a pinch of salt,” said seven-time champion Hamilton of what he had seen so far.
“McLaren won the constructors' last year. We expect them to be one of the quickest, if not the quickest, as with Red Bull, who dominated for many years.
“For us, we're just trying to improve. I haven't done the long run yet so I'm about to do it this afternoon and I'll get a bit of a better understanding of how this car behaves in a race stint.”
Hamilton, who moved from Mercedes at the end of last season, has so far done only short stints in the car.
