Franco Colapinto and Pierre Gasly have lost their respective P8 and P10 finishes at the Mexico City Grand Prix, with the Alpine pair penalised after the race for separate yellow flag infringements.

The Frenchman had outqualified his team mate at the Autodromo Hermanos Rodriguez, but it was Colapinto who enjoyed the better start and improved from P11 to P7 over the opening laps.

Although they managed the 71-lap affair well to secure a hard-fought double points finish for Alpine, they were later summoned to the stewards for failing to slow under yellow flags – Colapinto doing so in a single yellow sector, and Gasly in a double.

Their subsequent penalties – 10 seconds for the Argentine driver and a stop-and-go for Gasly – have dropped them down the final classification and promoted Red Bull's Isack Hadjar and Haas newcomer Ryo Hirakawa to P9 and P10.
