Normally, the Grand Prix of the Americas, as the MotoGP round at COTA in Austin is known, is a straightforward affair. 24 MotoGP riders line up on the grid, and 23 of them stage a fierce battle over who is going to come second behind Marc Márquez.

The Repsol Honda rider has won every single one of the five editions staged at the Circuit of the Americas. In fact, the Spaniard has never been beaten in any of the nine MotoGP races he has contested on American soil, at Laguna Seca, Indianapolis, or in Austin.

Will someone finally break Márquez’s winning streak in the US? On the evidence of the 2018 season so far, the only person capable of beating Márquez at one of his strongest tracks is Marc Márquez himself.

In Argentina, the Repsol Honda rider managed to thoroughly sabotage his own race. First by stalling his bike on the starting grid – a grid already thrown out of kilter by the changing weather.

Then by trying to make up for the time he lost serving a ride through penalty for a multitude of infractions at the start by charging through the field like a wrecking ball, slamming into one rider after another, taking out his arch nemesis Valentino Rossi, before being hit by another penalty, this time adding 30 seconds to his race time and demoting him out of the points.

After the race and in the intervening days since, Rossi has gone on the attack, calling Márquez a dangerous rider who is a threat to everyone on the track with him. He doesn’t feel safe on the track with Márquez, Rossi said.

Rossi’s remarks, while understandable, should be seen within the wider context of his vendetta with Márquez, after he lost the 2015 championship, which Rossi blames entirely on deliberate interference by Márquez.

Further stoking the fire, Rossi was pictured in a social media post with a framed picture of the Argentina incident lying on a sofa at his dirt track ranch.

Whatever the root of Rossi’s remarks, there can be no doubt that they are a distraction, both for Márquez and for Rossi himself.

When the pair arrive at the Circuit of the Americas in Austin, they will face questioning on one subject only. And that won’t be Márquez’s chances of winning on Sunday.
