Joan Barreda was the pacesetter on the eighth stage of the 2017 Dakar Rally, as overall leader Sam Sunderland added to his advantage over his nearest rivals.
Barreda, who had led the rally early on but was thrown virtually out of contention by a one-hour penalty for illegal refuelling, was unmatched throughout Tuesday's Uyuni-Salta stage.
The Spaniard led the Bolivian part of the special, (originally due to be 492km, but shortened due to rainfall by 73km), and pulled further ahead once the race returned to Argentina.
Sherco's Joan Pedrero ran Barreda closest before the border, but lost time in the Argentina section.
As such, it was KTM duo Matthias Walkner and Sunderland who made up the top three, with Walkner finishing 3m51s behind Barreda and just three seconds clear of Sunderland.
With his second stage win of the Dakar, and the 16th of his career, Barreda remains in ninth, more than an hour and 10 minutes adrift of the lead in the overall classification.
Crucially, Sunderland gained time on his main chasers, the Briton outpacing Husqvarna's Pablo Quintanilla and Yamaha's Adrien van Beveren in the stage.
Quintanilla and van Beveren remain second and third overall, trailing Sunderland by 21 and 29 minutes respectively.
Walkner moved up to fourth at the expense of KTM privateer Gerard Farres, but remains 34 minutes behind teammate Sunderland.
