Sebastien Ogier remains on course to win a third successive Mexico Rally after dominating on day three in Guanajuato.
The two-time defending world champion extended his lead by more than a minute after winning four of the eight stages on the penultimate day.
Volkswagen driver Ogier, who had an overnight lead of 10.9 seconds, won the first two stages of the day - the 11th and 12th - before also triumphing in the 15th and 17th.
"It has been a perfect rally up to now, everything is working like a dream. There is a very long stage tomorrow morning but with the lead we have we can afford to drive safely," Ogier told www.wrc.com.
His overall time of three hours 33 minutes and 27.4 seconds is one minute 15.2secs quicker than second-placed Mads Ostberg (3:34:42.6) of Citroen, who leads third-placed Andreas Mikkelsen (3:34:47.1) of Volkswagen by 4.5secs.
M-Sport's Welsh driver Elfyn Evans (3:35:56) is fifth overall, while Northern Ireland's Citroen driver Kyle Meeke (4:24:36.6) is 25th overall.
Ott Tanak, who had a narrow escape when his car left the track, plunged into a reservoir and subsequently sank in Friday's racing, was able to take part in Saturday's racing and is currently last in 28th.
