Austin MotoGP: Marc Marquez continues to dominate practice

The reigning world champion quickly retook his place at the top of the timesheets with his first flying lap of the session and comfortably remained there until the chequered flag.

His best time of 2m03.490s came early on in his second run and nobody could come within a second of beating it through the latter half of the session.

Ducati's Andrea Dovizioso showed good pace and managed to pip Marquez's Honda team-mate Dani Pedrosa for second in the final few minutes, with Andrea Iannone just 0.046 seconds behind in fourth on the Pramac Ducati.

Valentino Rossi continues his impressive start to the season and was the top Yamaha once again, rounding off the top five, albeit 1.303s off the ultimate pace.

Open class honours went to Aleix Espargaro once again, as he narrowly edged Stefan Bradl by 0.026s for sixth.

The LCR Honda rider enjoyed his moment in the spotlight when he went second for a long spell mid-session while the majority of the field headed back to the pits for set-up changes.

He finished the day ahead of Jorge Lorenzo, who was visibly unhappy with the traction of his Yamaha.

Cal Crutchlow and his former Tech 3 team-mate Bradley Smith completed the top 10.
