RB and McLaren were only joined by Sauber in running the softs in FP1, which ended with Yuki Tsunoda fourth ahead of Fernando Alonso and Max Verstappen in fifth and sixth for Aston Martin and Red Bull respectively.
Most of the pack headed out immediately at the start of the one-hour session where windy conditions prevailed in relatively cool temperatures, with all the early running conducted on the medium tyres – the C2 variety at last weekend's test.
