Jaume Masia took advantage of his first ever pole position to win his first Moto3 Grand Prix from Darryn Binder and Tony Arbolino at the Termas de Rio Hondo circuit in Argentina.

Starting from pole, Masia had to shake off a morning warm up crash and an awful start that nearly saw his Bester Capital Dubai KTM fire him straight off when the lights went out.

The Spaniard found himself at the front of the race early, but with a lead group of twenty riders, lead changes were often and the race never settled into any rear rhythm.

Two of the pre-race favourites John McPhee and Kaito Toba were out halfway through the race when the Scot collided with Alonso Lopez. Toba was caught up and whilst Toba and McPhee continued, neither were able to challenging.

Whilst the lead group remained at seventeen, however, the race looked between Masia, Binder, Arbolino, Gabi Rodrigo and Lorenzo Dalla Porta.

Going into the final lap, Dalla Porta led on the back straight, only to see his slipstream help propel Rodrigo into the lead. Binder pushed Dalla Porta well back. Masia took the lead two corners later from the home rider and despite a late scare into the final corner, the Spaniard held on to take his first Grand Prix win.

Binder tried to out-brake the Spaniard, but with no way through, he left Rodrigo with nowhere to go, forcing the Argentine wide, allowing Arbolino through to take the final step on the podium, leaving Rodrigo down in sixth.

Nico Antonelli was fourth, ahead of Sasaki with Rodrigo, Dalla Porta, Dennis Foggia, Marcos Ramirez and Kaito Toba rounded out the top ten, with the Japanese rider just 1.280 seconds off the win.

Andrea Migno was eleventh on his KTM ahead of Canet, who led large portions of the race, with Tatsuki Suzuki, Celestino Vietti and Raul Fernandez completing the point scorers.
