Twice defending world champion Marc Marquez maintained his unbeaten record in the United States with a decisive victory at the Indianapolis MotoGP in the United States.
Marquez bided his time in second place behind Jorge Lorenzo for most of the 27-lap race before making a decisive pass of his fellow Spaniard at the end of the home straight with three laps left.
The Honda rider was never seriously challenged after that as he crossed the line 0.688 seconds ahead of Yamaha rider Lorenzo at the Indianapolis Motor Speedway.
World championship leader Valentino Rossi of Italy was nearly six seconds back in third place on his Yamaha, just ahead of Spaniard Dani Pedrosa on a Honda.
Marquez has never been beaten in motorcycling on three different American tracks and has won for the past five years in Indianapolis in Moto2GP and MotoGP.
Marquez struggled in the first part of the season, but is hitting form now.
His latest triumph came after he escaped injury in a crash during practice in the morning.
With his third victory of the season, Marquez picked up 25 points to jump from fourth to third place in 2015 championship standings.
After 10 of 18 races, he is 56 points behind Rossi (195 points), who leads Lorenzo by only nine points.
The next round is in the Czech Republic.
