F1 champion Max Verstappen takes over driving duties for Red Bull as the teams tackle the penultimate day of pre-season testing in Bahrain.
Pierre Gasly set the fastest lap of the first day but hands the reigns over to team-mate Yuki Tsunoda for day two.
The three-day event is the final chance for teams to hone in on optimum configurations ahead of the first race of the year at the same venue next weekend.
McLaren's line-up is yet to be cemented due to Daniel Ricciardo's illness that saw the Australian miss the first day of running.
