The Yamaha rider was one of only two riders – the other being teammate Valentino Rossi – to opt for the soft front tyre, while the rest of the field went with the hard owing to the scorching track temperatures.
Vinales got the holeshot off the line from second and tried to break away from the pack, hoping that doing so would allow him to safely ease off later on to conserve his rubber.
But the Spaniard started having moments on the front end early on and, by lap nine, he had lost the lead to Petronas Yamaha man and eventual winner Fabio Quartararo.
