World champion Sebastien Loeb extended his lead over Citroen team-mate Mikko Hirvonen to 11.2 seconds as leg one of Rally Mexico concluded in Guanajuato.
The Frenchman won the Leon street stage and then gained more time on the Finn in deteriorating conditions despite finishing only eighth on the two evening runs through the superspecial.
Third-placed Mads Ostberg (Adapta Ford) maintained his 16-second cushion over Ford driver Jari-Matti Latvala through the three short stages, with Latvala's team-mate Petter Solberg finishing the first day in fifth spot overall.
With Loeb one of a number of drivers affected by heavy rain for SS11 and SS12, Nasser Al-Attiyah (Qatar Citroen) claimed his first World Rally Championship stage win on the opening run and Chris Atkinson (Monster Ford) enjoyed victory in the second.
Saturday's action begins with the 29.90-kilometres Ibarilla.
