Poor finishes cost the Irish as close friends Jérôme Lando Casanova and Julien Brun recorded rounds of 66 to get to 12 under par and open up a four-shot lead going into the final day at the Open de Bretagne.

Paul McBride was three-under with two holes to go but finished double-bogey, bogey to card a level par 70 that left him tied 37th on one-under-par at Golf Bluegreen Pléneuf Val André.

St Anne’s Cameron Raymond dropped four shots in his first six holes but while he played the next eight holes in four-under, he bogeyed the last for a 71 that left him tied 47th on one-under.

it was also a trying day for Gavin Moynihan, who was one-under with four holes to go but double-bogeyed the 15th and bogeyed the 16th and 17th to card a 73 that left him tied 55th on three-under.

Lando Casanova has not dropped a single shot all week as he aims for victory on home soil, while his countryman and playing partner Brun matched his four under par score on Saturday with a round that included six birdies and two bogeys in wet and windy conditions at Golf Bluegreen Pléneuf Val André.

Austrian Niklas Regner and in-form American Chase Hanna are the closest challengers to the home favourites at eight under par.
