Halfway through final practice, top 10: Martin, M.Marquez, A.Espargaro, Bagnaia, A.Fernandez, Vinales, A.Marquez, R.Fernandez, Binder, Bastianini.
Friday leader Brad Binder is currently ninth (medium tyres) with KTM team-mate Jack Miller 13th (medium-soft).
Title leader Francesco Bagnaia, who will join the likes of Marc Marquez and Fabio Quartararo in Qualifying 1, is now the quickest on the medium rear tyre, in fourth.

Normally of course, with the Sprint race before the main race, teams can examine the soft tyre after the Sprint and decide if it can last the full Sunday distance or not.
Jorge Martin, Marc Marquez adn Aleix Espargaro are setting the early pace. All three have the soft rear tyre, but around half the field has the medium as they rush through data gathering to work out if the soft might last the full distance this afternoon or whether they will need to use the medium.
