The second day of pre-season testing in Bahrain has begun, with Carlos Sainz currently topping the timesheets at the halfway point.
Proceedings kicked off at 07:00 GMT and Fernando Alonso was amongst the first to hit the track, having come within three hundreths of a second of Max Verstappen's fastest time at the end of Day 1.
The Aston Martin driver will be in the car for the entire day, while reserve driver Felipe Drugovich remains on standby due to Lance Stroll's absence. The Canadian suffered a cycling accident during pre-season training.
Lewis Hamilton became the first driver to hit double figures on Friday's lap count following Mercedes' positive assessment of their opening day in the "much calmer" W14.
While it was a slower start for Red Bull – with the mechanics seemingly busy working on the RB19 initially – Sergio Perez soon hit the circuit with flow-vis paint on his car.
Also busy setting lap times was Sainz, who had a solid opening session on Thursday.

Yuki Tsunoda has been the busiest in terms of mileage, with the AlphaTauri driver having amassed 43 laps so far.
