Colm Moriarty posted a second consecutive four under par 66 and take control of the Skandia PGA Open at the tournament's halfway stage.
Moriarty's room-mate for the week - Dubliner Stephen Browne - was two strokes behind the Athlone man with two holes to play but finished the day in the worst possible fashion with a triple bogey eight and a double bogey five to fall back to one under.
Justin Kehoe (four over) and Tim Rice (nine over) missed the halfway cut of three over par.
