Oscar Piastri carried McLaren's Bahrain Grand Prix practice domination through to pole position, but his Formula 1 world championship leading team-mate Lando Norris was only sixth fastest.
Mercedes duo George Russell and Kimi Antonelli initially qualified in second and fourth but both were handed one-place grid penalties for a red flag breach.
Mercedes sent the drivers to the end of the pitlane when the estimated restart time was issued rather than the finalised restart time, leading to a grid drop.
That puts Leclerc's Ferrari onto the front row alongside Piastri and moves Pierre Gasly's Alpine into fourth.
