Toro Rosso driver Carlos Sainz has been handed a three-place grid penalty for the Russian Grand Prix after being deemed "predominantly to blame" for a collision with Lance Stroll in Bahrain.
The duo came together at turn one on lap 12, when Sainz connected with the side of Stroll's Williams shortly after leaving the pits.
"Video evidence showed that car 18 [Stroll] was on the normal racing line," read a statement from the FIA.
"Car 55 [Sainz] left the pit lane and made a very optimistic attempt to pass car 18 into the corner. The stewards decided that the driver of car 55 was predominantly to blame for causing the collision."
Discussing the incident after the race, Stroll - who is yet to complete a grand prix - said: "I saw Sainz coming out of the pit lane, I was 50 or 60 metres in front of him in the braking zone, and was already turning in and he drove into my side.
"There is not much else to say, as I have just seen the video and it was ridiculous. I think the race wasn't going badly. I had a bad start and lost a couple of positions, but boxed early and had a really good beginning to the stint on the soft tyres.
"I am just disappointed and hope my luck turns round sometime soon. I can be frustrated, but it won't get me anywhere. On the bright side there are many races to go."
Sainz has also been awarded three penalty points, taking his total for the 12-month period to seven. Drivers who accrue 12 will have their super licence suspended for one race.
