Kris Meeke rolled the dice by sticking with hard compound tyres, and it paid off on Saturday as he extended his lead over Sebastien Ogier heading into the final leg of the Rally of Mexico.
Britain's Meeke, who is seeking his fourth career victory, decided to gamble and go with his Michelin tyres despite the threat of rain.
Luckly for him, the weather forecasters were wrong and he was able to seize a commanding 30.9-second advantage over defending world champion Ogier heading into Sunday's final day of racing.
Citroen driver Meeke won one of nine speed tests Saturday in the mountains near Leon.
"It has been a perfect weekend so far," said Meeke. "That was going to be the defining loop of the rally. I had to make it stick on this loop and it worked."
Ogier won two tests in his Ford Fiesta and ended 39.6 seconds in front of Thierry Neuville, who also captured a stage.
Sunday's final leg comprises two tests. After a mid-morning start, crews drive the 32.96km La Calera before the 21.94km Derramadero live TV Power Stage, which offers bonus points for the fastest five drivers.
