Khairul Idham Pawi took a dominant maiden Moto3 victory in just his third start in the series, having beaten the field by an astonishing 26 seconds in Argentina.
Despite the track being wet, a few dry patches and no rain meant the entire field kicked off the race on slicks with the exception of Livio Loi.
Although he was 10th on the grid, Loi understandably rocketed through the field at the start.
However, he could only settle into second as Pawi had an even better launch, and lapped several seconds quicker despite running on dry tyres.
Impressively, the Malaysian rookie built a lead of 20 seconds over the course of just eight laps.
As the track dried out, most of Pawi's advantage in pace disappeared, but he continued to stretch his advantage.
Loi on the other hand quickly dropped down the field, eventually settling for 16th.
Estrella Galicia rider Jorge Navarro and another Malaysian Adam Norrodin separated themselves from from the rest of the chasing pack at the halfway point onwards.
Norrodin waited for his chance to overtake until the final lap, but lost control at the very final turn of the race. He suffered a violent crash, but managed to make it to the finish on foot in 11th.
Navarro secured second as a result, with Brad Binder completing the podium after a race-long battle with several others. The South African was closely followed by Andrea Locatelli, Joan Mir and Hiroki Ono.
John McPhee passed Jorge Martin to take seventh with the Spaniard losing eight seconds during the final stages - but still finishing eighth.
The top 10 was completed by Jakub Kornfeil and Qatar winner Niccolo Antonelli.
Aron Canet was part of the second group, running as high as fourth, but failed to finish the race after crashing out.
