Marc Marquez took another step closer to the Moto2 World Championship after thrashing the opposition at Indianapolis, winning by over five seconds. The stage seemed to be set for a head-to-head battle with Pol Espargaro but Marquez was untouchable from the moment he took the lead on lap four.

Andrea Iannone was quickest off the line from the outside of the front row but Dominique Aegerter was on a mission, climbing up to third behind polesitter Espargaro. The Swiss rider wasn’t done there, breezing past Pol at the start of lap two, and just seconds later, he’d deprived Iannone of the lead. The surprises didn’t stop there as Aegerter not only led, but started to disappear up the road. Marquez was quick to notice the break though and swiftly moved into second before wiping out Aegerter’s advantage.

Within a single lap, the one second lead had been wiped out and Marquez overhauled the Technomag Suter in short order, diving up the inside into turn one on lap four. Espargaro was languishing down in fifth and was powerless to stop his compatriot disappearing at the front. Fourth placed Julian Simon was the first to be dispatched on lap five before Pol followed Iannone past Aegerter moments later. The top three on the grid were back at the front of the field.

At the start of lap eight, Espargaro got the better of Iannone for second and it quickly became apparent that the Italian was hobbled as Simon snatched third later in the lap. The former Moto2 runner-up couldn’t keep up with the two ahead of him but a first podium in fifteen months was still a sensational return to form.

By the time he’d taken second, Espargaro had 3.6 seconds of empty track between himself and Marquez, a margin that would only get bigger as Marquez cruised to his fifth win of the year, extending his championship lead to 39 points.

With Simon third, the two other title contenders were forced into damage limitation mode. For Thomas Luthi, it was mission accomplished despite having started on the third row, recovering up to fifth between the Marc VDS riders Mika Kallio and Scott Redding. Aegerter faded back to seventh but his demise was nothing compared to Iannone who was beaten to eighth by Simone Corsi.

The two remaining Brits in the field both toiled for little reward. Bradley Smith made a bright start but the poor pace of the Tech 3 this weekend would bring his unbroken streak of points finishes to an end. Smith was sixteenth while Gino Rea was twentieth past the chequered flag.
