Moto2
In Moto2 we are guaranteed a first-time winner at Austin. The winners of the last three Moto2 races at the circuit – Alex Rins, Sam Lowes and Maverick Vinales – have all graduated to MotoGP.
The only other rider to have won a Moto2 race in Austin is Nico Terol, in 2013, but he no longer competes in Moto2.
Similarly, all three podium finishers from last year – Rins, Lowes and Johann Zarco – are all competing in MotoGP this season.
Like Vinaless in the premier class, Franco Morbidelli has won the opening two races of the season in the intermediate class, a feat last achieved by Jorge Lorenzo in 2007 – when the machines were 250cc two-strokes. Morbidelli is also the first Italian rider to win consecutive races in the class the late Marco Simoncelli in 2009.
