AUSTIN, Texas (Reuters) - Honda's MotoGP leader Marc Marquez won for the fourth year in a row at Austin's Circuit of the Americas on Sunday while his bitter rival Valentino Rossi was one of several riders who crashed out.
Spain's Marquez was again in a race of his own at the Texan track, starting on pole position for the fourth successive year and pulling away after a brief tussle for the lead on the opening lap with Yamaha's reigning world champion Jorge Lorenzo.
Lorenzo finished second, 6.107 seconds behind his compatriot, with Italian Andrea Iannone third on a Ducati.
The win was Marquez's second in a row, and 26th in MotoGP, and left the double world champion on 66 points after three races. Lorenzo moved up to second overall on 45, with Rossi remaining on 33.
