At the start, Márquez and Dovizioso shot away, but they were so engaged with one another that Fabio Quartararo was able to pass them and lead, with Jack Miller and Rins in the thick of it. This was battle, cut and thrust, daggers drawn. But as it must, the track begins to act as a filter, letting through those with what’s needed and screening out those without. Quartararo led five laps but then it was Dovizioso, and two laps later Márquez, leading the next 11. A look at the times shows Quartararo’s tire dropping at about lap 11, so his strong run, though marvelous for this 20-year-old Frenchman, couldn’t last.
