Jack Miller got the holeshot from second on the grid at the start of the race, but soon dropped behind polesitter Bagnaia on the sister factory Ducati and the fast-starting Gresini bike of Bastianini in third, paving the way for a two-horse race for victory.
Bastianini started piling pressure on the Spanish GP winner in the second half of the race, with the two circulating just a few tenths away from each other on the 4.1km circuit.
