Max Verstappen has picked up where he left off at Circuit de Catalunya by leading the morning session of day two in the first in-season test, in a relatively low-key session.
The Spanish Grand Prix winner, who became the youngest driver to claim a victory in F1 history, spent the session familiarising himself with his Red Bull having replaced Daniil Kvyat in the team in the build up to last weekend's race.
The Dutch 18-year-old produced an impressive lap in the final hour of the morning on soft tyres to extend his advantage at the top with a 1m 23.267s – just two-tenths off his own qualifying time from Saturday.
The session was very briefly red-flagged in the final half an hour when Manor's Jordan King ran off track at turn seven and spilled gravel on to the circuit. The debris was quickly cleared up by track marshals to allow drivers a quick blast before the lunch break.
Stoffel Vandoorne continued to demonstrate McLaren's gains by taking second on the timesheet ahead of Kvyat, also getting familiar with his Toro Rosso, while Kevin Magnussen continued Renault's extensive testing with its new B-spec engine configuration.
Pascal Wehrlein, who subbed in for Esteban Ocon at the last minute at Mercedes, claimed fifth having completed a full race distance of laps, in front of Esteban Gutierrez in the Haas.
The bottom of the timesheet read as the battle of the reserve drivers with the addition of Felipe Massa in the Williams testing a new aero specification on the FW38.
Ferrari academy driver Antonio Fuoco claimed seventh and notched up 56 laps with an impressive opening outing for the Italian manufacturer.
Alfonso Celis Jr narrowly pipped Massa in his Force India while King in the Manor completed the runners.
