Marc Marquez claimed his third pole in as many outings at the Argentina GP, despite suffering a heavy fall at the end of an eventful day's action.
Two-time MotoGP premier class world champion Marquez, who lost his title to Jorge Lorenzo in 2015, was the class of the field during qualifying at Termas de Rio Hondo - having earlier topped the timesheets in two practice sessions.
Valentino Rossi was the only man able to get within half a second of the pole-securing time of one minute and 39.411 seconds - the Italian finishing 0.375secs back.
However, things did not run entirely smoothly for Marquez, who was the last of several riders to fall at turn one during qualifying sessions delayed by an earlier incident involving Scott Redding in FP4.
Race direction opted to red flag the final practice session on safety grounds, after an issue with the rear of Redding's bike resulted in debris being scattered across the track.
Lorenzo fell at turn one when FP4 resumed, before claiming third position behind Marquez and Rossi in the subsequent qualifying.
Marquez won from pole in Argentina in 2014, but failed to make the most of topping the grid 12 months ago, when he retired.
