18-year-old Mercedes rookie Kimi Antonelli has stunned the Formula 1 world after he became the youngest-ever pole-sitter of all race formats in F1 history.
The Italian racer shot to the top of the timesheets after team-mate George Russell looked set to claim pole position, but Antonelli stole the show with a lap time of 1:26.482 in the Miami Grand Prix sprint qualifying.
The Mercedes star now holds the record for the fastest lap at the Miami International Autodrome having also smashed the record by two and a half years for being the youngest-ever driver to claim pole position in any format.
McLaren will line up behind Antonelli on the grid for Saturday's sprint, with Oscar Piastri finishing SQ3 in P2 ahead of Lando Norris in P3.
Further down the order Red Bull got off to a disappointing start ahead of the sprint race this weekend with Yuki Tsunoda making an SQ1 exit on Friday.
This marks the first time this year the Japanese racer has gone out in a Q1 or SQ1 session, with team-mate Max Verstappen also struggling with his RB21 throughout the session.
After claiming his first sprint pole position and race victory with Ferrari at the first 100km event of the year in China, seven-time champion Lewis Hamilton was wrestling with his SF-25 throughout SQ3, finishing sprint qualifying in P7.
