With large storms hitting the Circuit of the Americas (COTA) on Saturday morning, all three classes have had their Free Practice 3 session canceled.
The lightning and heavy rain have simply left the track too dangerous to venture out on. This meant that several delays culminated in canceled sessions.
However, this weather had been predicted and resulted in a heavier focus than usual placed on Fridays Free Practice 1 and 2.
As a result, it was Maverick Viñales who came out on top, marginally ahead of Marc Marquez. The reigning champion is chasing his seventh COTA win. Moto2 saw Marcel Schrotter and his Dynavolt Intact GP bike lead the way in both Friday session. Romano Fenati dominated both Mot2 sessions on the VNE Snipers machine.
Qualifying is still due to go ahead as normal, however this is subject to the conditions at the time. They are scheduled to kick off at 20:10 (UK time) for Qualifying 1 and 20:35 for Qualifying 2.
