Rasmussen was back on form though as the racing moved to Mexico. He extended his own record of pole positions in the series to 15, claiming his fourth of the season. Ronhaar took second, while Opmeer’s best performance of the season saw him start third.
This time Ronhaar went backwards, starting on the hard tyre, as Opmeer, Josh Idowu (AlphaTauri), and Blakeley all streamed past on the medium rubber. The front four held station until the pit stops, as Idowu and Blakeley opted for earlier stops, followed by Rasmussen, and Opmeer pitting last of all – using the overcut to take the lead.
Boroumand and Ronhaar, now on the medium tyres, were carving through the pack and soon passed Rasmussen, who seemed to lose his cool. Clearly feeling he’d been run off the road by Ronhaar at the Ese del Lago chicane – picking up a track limits penalty – Rasmussen dive-bombed the Haas at the same turn on the next lap, scoring another penalty as well as a later grid position penalty for the next round.
Opmeer crossed the finish line over three seconds ahead of Boroumand, claiming his first win – and a first for Mercedes – since the one he took at the same track in 2021. Ronhaar kept third, while Rasmussen’s red mist saw him drop out of the points; with Blakeley claiming a sixth position that could prove vital at the end of the year.
