This morning Viñales calmly prepared for Sunday's race at the Termas de Río Hondo track, steadily upping his pace. He tried various tyre specs and bike settings, to reduce wheelspin in order to be able to put in a good challenge during the important FP2 session. He set a best morning time of 1'41.657s for 18th place, 1.830s from first.
The young gun again displayed his patience in FP2. He used most of the session to make some further set-up changes, before pouncing at the right moment. With 15 minutes of the available time left, the game was on. He quickened his pace to the 1'39s, setting a provisional third fastest lap before the general mini time attacks took place. He responded in the final minutes, concluding the session with a 1'39.345s lap for third place in the FP2 and combined free practice timesheets, 0.164s from first.
Rossi started the Argentina Grand Prix weekend on a more positive note. He worked diligently on his bike's setting in FP1 in preparation for the race on Sunday. Focusing on bike improvement rather than lap times, he ended the morning practice with a 1'40.827s best lap for tenth place, 1.000s from the top of the timesheets.
The Doctor used the second free practice to further fine-tune the balance of his bike, to match it to Termas de Río Hondo's layout, setting everything up for a final push at the end of the session. The Italian rider executed the plan to perfection. As various rivals were also trying to put in a hot lap, the Italian avoided traffic and posted a 1'39.441s lap, earning sixth position in both the FP2 and combined free practice results.
