The team finished the session with Lance Stroll in 18th and Fernando Alonso in 20th, but neither driver got in representative laps on soft tyres after a scrappy session.
Once again Stroll’s running was compromised by an issue outside his control as he lost time in the garage with a stuck left-front wheel.
It required some extensive hammering from a mechanic before it could be removed and he could continue. Alonso meanwhile made a mistake and had a spectacular spin early in the session.

Like others, when the Aston drivers went out at the end for a soft run, they were caught out by light rain that compromised lap times.
“Basically we had the normal start of the session,” Krack told Sky Sports F1. “Then we didn't manage with soft tyres to put the lap together. Fernando spun in Turn 8.
“We had an issue to remove the front-left tyre from Lance's car. Then we were not ready when the sky opened. We were on track with the new softs, and unfortunately, we could not set a lap.”
