While there were fears of rain, it was under a mild sky that the last free practice session of Moto3 took place in Argentina. An exercise where we went below the 1'50 per lap mark for the first time, thanks to a Romano Fenati from his good days riding a KTM in great shape.
Because there are three of them in the top three with one Brad Binder who led most of the exercise while Open up quickly acclimatized to the route he discovered. The best performer from the day before, Bastianini, is fourth with the first Honda, ahead Oettl et Law who narrowly misses the top 5.
Pawi, Navarro, Antonelli follow, so much so that you have to go up to tenth place to find any trace of fabio quartararo. The Frenchman has not yet found the solution to climb to the forefront but remains the leader of a Leopard team far from his performances last year. The other tricolors are a little further away with a Jules Danilo fourteenth and one Alexis Masbou always forced to remain anonymous since here he is twenty-eighth. His teammate McPhee is thirty-second and he is the only one to regret a fall just before qualifying which will begin at 17:35 p.m. French time.
