It was frantic stuff as all the cars headed out for all their final runs. Cars crawled as each searched for a tow down the main straight from each other.
Things then all came to a head at Turn 1 as Tsunoda and Sainz both crashed within seconds of one another.
The Japanese buried his AlphaTauri at T3 before the Ferrari driver span off spectacularly in sympathy, taking his front wing off – he was lucky not to do more damage.
The session was then ended before anyone could set another lap.
As a result, the top five was Leclerc, Hamilton, Verstappen, Gasly and Sainz – who may need a gearbox change.
The under-investigation Norris was sixth, with Perez behind. Fernando Alonso and a beleaguered Bottas, who was sent out early to give Hamilton a tow on the first run, coming home 9th and 10th.
