WATCH: Piastri crashes out of Sao Paulo Sprint in blow to championship hopes

Oscar Piastri dramatically spun into the barrier during the Sprint in Sao Paulo, putting a dent in his hopes of picking up maximum points in a remarkably tight championship battle.

Conditions around Interlagos were treacherous from the formation lap onwards, with parts of the track appearing damp and slippery, making it tricky to find a racing line that was both dry and effective.

This came to a head on Lap 7, when Piastri drifted onto the kerb at Turn 3. The slick surface sent up a spray of water, forcing him into a spin that ended with his McLaren crashing into the wall and out of the Sprint.

There were eerily similar incidents for Nico Hulkenberg and Franco Colapinto, both of whom dropped a wheel onto the kerb before finding the barrier. The amount of debris resulted in the red flag being waved, temporarily halting the session.
