George Russell went quickest in a twice red-flagged opening practice session at the Mexican Grand Prix, as Alex Albon and Oliver Bearman collided at Turn 9.
Russell set a 1m17.998s on the soft-tyre runs to go three-tenths faster than Ferrari's Carlos Sainz in a stop-start session, with the first interruption coming five minutes in to clear a sliver of debris sat ahead of Turn 1.
