A brilliant feat of defensive driving saw Oscar Piastri take a famous win at the Azerbaijan Grand Prix, helping his McLaren team move up to first in the constructors' championship for the first time in a decade.
Piastri was hounded by Charles Leclerc for the second half of the race after he passed the Monegasque with a daring move down into the first corner, but kept the Ferrari at bay despite a constant DRS disadvantage.
Sergio Perez had been trailing the pair for their entire battle, having been denied the chance to come out of the pits ahead of Piastri after some smart teamwork by Lando Norris, but was passed by the fast-finishing Carlos Sainz in the final laps.
Perez attempted to re-pass the Ferrari immediately, but the pair collided heavily and caused the race to end under a virtual safety car. Both were summoned to the stewards to explain themselves after the race, but the crash was eventually ruled a racing incident.
