The 60-minute evening session was interrupted early on when George Russell lost the rear of his Mercedes at Turn 16, breaking his front wing and triggering barrier repairs. On the restart, tension rose in the lane when Leclerc exited his Ferrari garage and struck Norris, shoving the McLaren against the wall and breaking its front wing. Leclerc’s 1m31.466s left him ninth after the pitlane clash, while Hamilton rounded out the top ten on 1m31.491s using mediums. Further back, Yuki Tsunoda managed 11th for Red Bull (1m31.708s) ahead of Haas’ Oliver Bearman (1m31.711s). With the Marina Bay surface evolving rapidly, teams will have much to digest ahead of final practice and qualifying on Saturday.
