"It was just plants that I missed, really. Both times he made big breaks to clear up. From my point of view I felt I didn't make too many unforced errors.

He's never won at the Waterfront Hall, reaching semi-finals in Belfast in 2005 and again two years ago.

"If I get on a run anything could happen," he said of claiming a first Northern Ireland Open title.
