Fernando Alonso topped the times for Aston Martin ahead of Ferraris Charles Leclerc and Red Bulls world champion Max Verstappen in opening practice for the Singapore Grand Prix on Friday.
Championship leader Oscar Piastri and his McLaren teammate Lando Norris managed only the fifth and sixth quickest times in the session behind the other Ferrari of Lewis Hamilton.
Spanish veteran Alonso, winner of the first Formula One race in Singapore in 2008, put in consistently fast times over the session and his best lap of one minute 31.116 seconds put him top of the time sheets for good.
