Marquez back on top of the timesheets during warm-up for the Austin MotoGP.

Vinales - who has inherited pole position after Marquez's grid penalty - is a close second, with title leader Crutchlow back on form in third.

Syahrin was taken to the Medical Centre for checks after a big highside on his outlap. Update from Monster Yamaha Tech3: 'Rider ok'.

Pedrosa is returning from a wrist fracture sustained last time in Argentina.

Riders have reported major problems with the bumpy surface, especially on the back straight and turn 18, despite efforts to grind down the bumps from turns 1-9 and 16-19.
