The European Tour championship is set for its final round with the British golfer and a slim lead after an alarming return leg.
Sam horsfield finished a second consecutive lap as leader in the classification of the Hero openBut he will regret an alarming result of nine that could give confidence to his pursuers on the last day in Birmingham.
Five birdies on a flawless ninth front made the British golfer seem destined for a dominant advantage as he found himself with a six-shot lead.
However, his form sank after the turn, going four above the last nine, a score exacerbated by a double bogey on the twelfth hole.
Oliver Farr and Mikko Korhonen shot 67, while a 66 for Rasmus Hojgaard meant he joined that duo just one hit from Horsfield at -13.
Chris Paisley and García Rodríguez, who went to the round, have a new shot back, but still have their respective chances on Sunday.
