American John Catlin produced a finish worthy of the immortal names carved on the Waterford Crystal trophy when he birdied three of his last four holes to claim a two-shot win in the Dubai Duty Free Irish Open at Galgorm Castle.

James Sugrue leads the home challenge but he lamented his lack of luck with the blade as a two-over 72 left him 10 shots off the pace with a round to play in the Dubai Duty Free Irish Open at Galgorm Castle.
