McLaren locked out the front row at the Spanish Grand Prix as arguably their most dominant weekend of the season continues.
Oscar Piastri knocked Lando Norris off provisional pole by more than two tenths of a second with an absolutely mighty lap at the death, as the pair continue to duel for the drivers' title.
Max Verstappen was beaten by more than quarter of a second by Piastri in every part of the session, but team-mate Yuki Tsunoda was the headline-maker on Saturday afternoon, setting the slowest time of the session to qualify 20th and last.
Lewis Hamilton struggled with his Ferrari early on after some issues in free practice, struggling through in 11th in Q1 before picking up the pace in Q2 to edge ahead of team-mate Charles Leclerc, putting eventually putting himself fifth on the grid, outqualifying his team-mate for just the second time in grand prix qualifying this year.
Franco Colapinto caused an almighty traffic jam in the pitlane with just a few minutes left of Q1, his car unable to pull away and leaving him stationary at the head of a large queue.
The Argentine was unable to set a final lap time, ending up parked at the pit exit, sending him out of the session early.
