Moto2: Marquez dominates at Indianapolis
Marc Marquez reasserted his authority over the Moto2 field by cruising to his fifth victory of the year at Indianapolis.
The championship leader hit the front by lap five of 26 and then calmly pulled away, his Monlau Suter crossing the line 5.9 seconds clear of title rival Pol Espargaro's Pons Kalex to extend his cushion in the standings to 39 points.
Espargaro got past Julian Simon to claim second, but the 2010 runner-up was still able to take his first podium of a very tough 2012 campaign with Avintia.
Marc VDS duo Mika Kallio and Scott Redding sandwiched Thomas Luthi in a close battle for fourth place.
Dominique Aegerter and Andrea Iannone both led for spells early on but could not sustain that pace and fell to seventh and ninth respectively, split by Simone Corsi.
