Romano Fenati gave Valentino Rossi's VR46 Moto3 team its first win after bumping his way to victory in Sunday's Moto3 Grand Prix of Argentina.
The battle at the front was intense from start to finish, culminating in Fenati steering his KTM inside Alex Marquez and leader Jack Miller at the penultimate turn, making contact with both.
Fenati, who has had a virus over the race weekend, swept to only his second grand prix win, and first since Jerez 2012. Despite the drama, and an investigation, the result stood but there was a long wait for victory to be celebrated as the French anthem initially belted out of the Rio Hondo circuit.
A delighted Marquez also benefited from the incident he started which to claim second for the Honda powered Estrella Galicia team.

The initial breakaway trio of Miller, Fenati and Efren Vazquez were reeled in by the chasing Estrella Galicia riders,who brought Livio Loi with them.
Loi celebrated his 17th birthday with a career best finish of fourth for the Marc VDS racer, blowing away his previous best of twelfth on the Kalex KTM, a spectator as the controversy unfolded for the podium spots after an excellent chase to catch the frontrunners.
Alex Rins finished fifth on the second Estrella Galicia bike just ahead of Efren Vazquez in sixth who faded from his early position at the front for SaxoPrint-RTG.
Isaac Vinales finished in seventh for Calvo team. There was more drama behind the Spaniard across the line as Danny Kent was taken out by his Husqvarna team-mate.

Tenth went to rookie Enea Bastianini for the Go & Fun team.
Alexis Masbou was eleventh for Ongetta Rivacold ahead of Aspar rider Juanfran Guevara in twelfth.
The Mahindras of Alessandro Tonucci for the CIP team and Ambrogio rider Brad Binder were next to cross the line in 13th and 14th respectively. Ongetta's Zulfahmi Khairuddin claimed the final championship point in 15th.
John McPhee was battling in the chasing pack when he lost the front of his RTG bike with 14 laps remaining.
Italians Niccolo Antonelli and Bagnaia both crashed out in separate falls shortly after the Scotsman.
Czech hopes ended on lap one when Calvo rider Jakub Kornfeil was knocked out of contention by Francesco Bagnaia. Just a few corners later Karel Hanika crashed into Andrea Locatelli.

Miguel Oliveira didn't make it to the end of the first lap before a failing clutch forced the Portuguese rider back to the pits to retire.
