Pierre Gasly has accepted responsibility for the heavy crash which prematurely ended his first test for Red Bull and put the team's participation in the final day in jeopardy.
Gasly, who took the seat vacated by Daniel Ricciardo's move to Renault, lost control of the rear of the car on the high-speed, uphill run through Turn 9. Onboard replays appeared to show the Frenchman dip a wheel on to the grass just before the approach the entry to the corner.
That caused him to spin off the circuit, across the gravel and into the tyre barrier, wrecking the left-hand side of his car.
