What happened: On lap 32 of 66, Williams brought Alex Albon and Carlos Sainz into the pits together for a coordinated double stop, fitting both cars with fresh hard tyres. The stacked stop is a strategic gamble aimed at making one final set last to the checkered flag.

Why it matters: A double stack minimizes total time lost in the pit lane but forces the second car to idle behind the first, ceding precious seconds. With roughly a third of the race left, tyre durability on the hard compound will decide whether Williams can hold its track position to the finish.

What to watch: Watch whether the hard tyres survive the final stint without hitting a cliff, and where Albon and Sainz rejoin in the running order after the stacked stop.
