In FP4, the PETRONAS Yamaha SRT riders experienced a drastic change in conditions, as the sun broke through the clouds. Morbidelli and Quartararo started the session with wet tyres, but the track rapidly began to dry, allowing both to change onto slicks in the final minutes. Morbidelli was fourth fastest in FP4, while Quartararo placed 14th.
In Q2, Quartararo had a solid session, setting the ninth best time of 2:04.941 on his second attempt with the soft tyre compound. As it happened in Argentina a fortnight ago, the Frenchman will start from the third row of the grid. Morbidelli will be just behind his teammate tomorrow, on the fourth row, thanks to a 2:05.278 lap that lifted him to tenth place.
The 20-lap MotoGP Grand Prix of The Americas takes place at 2pm local time on Sunday.
