Maverick Vinales gets the better of Marc Marquez during opening practice for the Austin MotoGP round.

Both riders set their best time while using the medium compound tyres front and rear.

Andrea Dovizioso was the first of three Ducatis in the top six, while rookie Johann Zarco continued to impress with fourth for Tech 3.

Vinales' team-mate Valentino Rossi once again made a slow start to the weekend, in eighth, while using the soft tyres.

Cal Crutchlow was the only faller...
