The first running of the new F1 Sprint format played out on the streets of Baku on Saturday afternoon.
There was no shortage of action in the opening stages with George Russell and Max Verstappen going wheel to wheel before Yuki Tsunoda collided with the wall at turn 13, bringing out an early safety car.
Leclerc's grip on the lead lasted the better part of eight laps with Perez cruising past the Monegasque driver at turn one with help from Red Bull's immense DRS.
The Mexican scampered off into the distance to take a well-earned victory, while Leclerc held off Verstappen to secure a valuable eight-point haul for Ferrari.
