Jari-Matti Latvala's hat-trick of stage wins on the morning of day three has enabled him to open up his lead on Sebastian Ogier to over a minute while Thierry Neuville suffered a second stoppage.
Starting down the order by virtue of his awful start to the WRC season, which saw him fail to finish in either Monte Carlo or Sweden, Latvala has continued to make his advantageous road position pay to extend his stage win count to eight in Mexico to pull out a 1m 16.3s lead on his Volkswagen Motorsport team-mate Ogier.
The Finn has mastered the treacherous longer runs this morning to more than double his overnight lead as the pair inch clear of Hyundai's Dani Sordo and VW's Andreas Mikkelsen.
The biggest mover of the morning was M-Sport's Mads Ostberg who claimed fifth from Hyundai's Hayden Paddon, as the Ford-powered trio of Ott Tanak, Martin Prokop and Lorenzo Bertelli completed the WRC premier class runners.
It was a disastrous morning for M-Sport's Eric Camilli who crashed out just 2km from the end of SS11 Ibarrilla and sustained damage to the front-right of his Ford Fiesta RS WRC which effectively ruled him out of the running.
Heartache was also shared by Neuville, who having crashed out yesterday, suffered another off on SS12 under Rally 2 regulations and required precautionary medical attention.
