Marc Warren took a one-shot lead at the Portugal Masters on Thursday but speculation that the European Tour could witness a round of 59 at the rough-free Victoria Clube de Golfe proved premature. Scotland's Warren began with six straight birdies but a bogey on the seventh stalled his momentum before he went on to make three further gains in an eight under par 63. Callum Shinkwin, David Lipsky, Eddie Pepperell, Matthew Baldwin and Mikko Korhonen are all a shot back.
