MONTREAL (REUTERS) - Toro Rosso driver Carlos Sainz will take a three-place grid penalty at the Azerbaijan Grand Prix as punishment for causing a collision at the Canadian Grand Prix on Sunday.
Race stewards found the Spaniard had made a dangerous move that caused a collision with French driver Romain Grosjean's Haas before he then hit Felipe Massa's Williams and shunted the Brazilian out of the race.
Sainz accepted he had been at fault, apologising to his rivals on Twitter.
"Apologies to @RGrosjean and as a consequence @MassaFelipe19 Romain was simply on my blind spot and never got to see him. Glad we are all OK," he said.
The stewards ruled that while the collision was not caused by a deliberate act, Sainz had made a "careless and potentially dangerous assumption" that there was no car alongside and he could move track position safely.
