Marc Marquez wins third straight Grand Prix of the Americas

Marc Marquez has won world championship titles in three different categories

Spanish World Champion Marc Marquez won the Grand Prix of the Americas for the third successive year on Sunday.

After a fifth-place finish in the 2015 MotoGP season-opening race in Qatar, the 22-year-old Honda rider finished more than 2.3 seconds ahead of Ducati's Andrea Dovizioso in Texas.

Nine-time world champion Valentino Rossi was third on a Yamaha.

Danny Kent, Moto3, and Sam Lowes, Moto2, became the first two GB riders to win on the same day since 1977.

The last time that happened was in 1977, when Mick Grant, 250cc, and Barry Sheene, 500cc, won their races in Sweden.

Leopard Racing's Kent won by over 8.5 seconds from Frenchman Fabio Quartararo, while Lowes held off France's Johann Zarco for his victory.

Danny Kent, 21, made a return to Moto3 in 2014
