Maverick Vinales continued his perfect start to 2017 as he topped first practice for the Grand Prix of the Americas.

MotoGP championship leader Vinales ended FP1 0.577s clear of Austin specialist Marc Marquez, who has traditionally dominated in previous seasons, winning all four races at the Circuit of the Americas since 2013.

Marquez led team-mate Dani Pedrosa after the first runs but Vinales soon stamped his authority on proceedings, being the first and only man to dip into the 2m04s on Yamaha.

Andrea Dovizioso went third ahead of Johann Zarco and Alvaro Bautista late on with the former using a soft rear tyre.

Like Ducati team-mate Dovizioso, Lorenzo opted for the soft rear tyre and improved significantly on his initial benchmark to go sixth.

Dani Pedrosa ended up seventh and was just over a second shy of Vinales’ benchmark.

Like it has been for the whole of 2017, Valentino Rossi lagged well behind his younger team-mate and languished outside the top 10 before putting on two soft tyres to go eighth fastest.

Aleix Espargaró and Danilo Petrucci were ninth and tenth fastest respectively.

Cal Crutchlow recovered from an early crash at Turn 6 to end first practice in 11th ahead of Jack Miller.

FP2 for MotoGP gets underway later this evening at 2005 BST.
