Kevin Moore and Jonathan Corke in semi-finals
Reigning Isle of Man Men's Golf Champion Paul Lowey has been knocked out of this year's event.
The five-time winner from Rowany was beaten by two-time former title holder, Kevin Moore, by the narrow margin of one hole at Ramsey last night (Wed).
Moore will now face Jonathan Corke in the semi-finals.
The other last four contest will be between another former winner, 2010 champion, Daryl Callister and Tom Gandy.
In the Ladies Championship, the finalists from a year ago are both through.
Champion, Breeshey Jansen, was pressed hard by Catherine Cassidy before a strong finish and Shirley Price overcame Jane Gaines in a tight contest.
Price will play Joy Morris and Jansen faces Lynda Simpson for a place in the final on Saturday.
