If the big question at the Circuit of the Americas was "Who can beat Marc Márquez?" then we found out the answer on Sunday: Nobody. There were only two brief moments during which Márquez was not leading the MotoGP race. Off the line, Jorge Lorenzo was a fraction quicker going into Turn 1, but Márquez turned earlier and already had the lead on the exit. Lorenzo tried once more into the hairpin of Turn 11, but overshot and ran wide, Márquez taking back the lead immediately.
After that, Márquez was gone. Andrea Dovizioso and Jorge Lorenzo kept Márquez honest for a couple of laps, but the Repsol Honda rider's relentless pace forced them to concede. Márquez went on to win his fourth straight Grand Prix of the Americas, and his tenth straight win in the United States of America. Since ascending to MotoGP, he has never been beaten on American soil.
There are plenty of adjectives you could throw at Márquez' performance – imperious, dominant, superlative – but perhaps the best word to sum up Marc Márquez at the Circuit of the Americas is "Unbeatable." His rivals will have to wait another year to try to find a way of stopping him.
