BURIRAM, Thailand – Fabio Quartararo led a Yamaha sweep of the top three positions during MotoGP practice on Friday at the Buriram Int’l Circuit.

Quartararo shot to the top of the practice charts in the final moments of practice, leading the Yamaha onslaught with a fast lap of 1:30.404 aboard his Petronas Yamaha SRT bike.

Maverick Viñales was second fastest aboard one of the two factory Yamaha bikes, .193 seconds off the pace set by Quartararo. Franco Morbidelli was third fastest on the second Petronas Yamaha SRT.

Jack Miller broke up the Yamaha party at the front of the field by going fourth fastest for Pramac Racing, with Valentino Rossi giving Yamaha four bikes in the top-five after going fifth fastest.

Marc Marquez had a fairly rough afternoon, which started with a massive high side crash in the first practice. He was taken to a local hospital and was declared fit to compete despite some lower back pain.

Despite the crash, Marquez was able to return for the second practice and set the sixth fastest time of the weekend thus far.

Aleix Espargaro, Andrea Dovizioso, Joan Mir and Alex Rins completed the top-10 on the overall MotoGP practice charts Friday.
