And while it looked like the updates Mercedes have brought to Barcelona had improved his auto, teammate Valtteri Bottas set the pace in the morning session, posting a time nearly a second faster than Hamilton.
Australian Ricciardo's vehicle had some eye-catching aerodynamic upgrades for the start of the European season and ended 0.133 seconds slower after crashing in the morning, while Verstappen was third.
The MCL33 featured a brand-new, radical nose at the Circuit de Catalunya as part of their long scheduled update to try and bring the vehicle closer to competing with the top three teams.
The early part of the sessions was marked by several off-track excursions, with Sebastian Vettel, Valtteri Bottas, Marcus Ericsson, Brendon Hartley and Romain Grosjean all visiting the gravel traps, fortunately without any outcome.
Bottas was fastest with a lap of 1 minute, 18.148 seconds at the Circuit de Barcelona-Catalunya on Friday, almost a second quicker than teammate Lewis Hamilton, who was second fastest.

The MCL33 features a revised nose and front wing, which appeared to offer some improvement with a time 0.359s off Raikkonen.
Vettel said the updates brought by Ferrari to Spain - which included the mounting of the mirrors to the halo and tweaks to the SF71H's floor - all "seemed to work".
