for F1 test results [Saturday AM].
Max Verstappen has topped the timesheets on the third morning of Formula 1 pre-season testing at the Circuit de Catalunya in the Toro Rosso.
The Dutchman, who will become the youngest driver to start an F1 race next month aged just 17, powered to the top of the timesheets mid-way through the morning, his benchmark lap of 1min 24.739secs proving 1.4secs quicker than Lewis Hamilton.
Completing 60 laps, Verstappen's efforts came before forecasted light rain made its presence felt ahead of lunchtime, consigning most to the pit lane as the chequered flag fell for the lunch break.
Behind Mercedes' Hamilton, Sebastian Vettel progressed to the third fastest time having suffered an off on his out-lap between turns four and five right at the start of the session. The German lost the SF-15T on the exit of turn four and beached it in the gravel trap, forcing a red flag after just 30secs.
Daniil Kvyat mirrored team-mate Daniel Ricciardo in practising pit-stops initially before getting to work on lap times, the Russian going fourth fastest, ahead of Felipe Massa in the Williams, Force India's Pascal Wehrlein and Lotus' Pastor Maldonado.
Following a productive Friday, McLaren's Saturday got off to an inauspicious start when Jenson Button stopped on track after just 7 laps, though he has since ventured out again.
Similarly, Sauber spent much of the morning tinkering with the gearbox on the C34, meaning Marcus Ericsson didn't get out on track until rain began to fall.
