Marc McCann scored twice in the second half at Lakeview Park

Gary McCutcheon gave the Ports a 1-0 interval lead by firing home from six yards after Wesley Boyle's cross had been mishit by team-mate Alan Teggart.

McCann made it two on 61 minutes with a neat finish from an acute angle.

The former Glenavon man scored again two minutes later when he latched on to a long ball out of defence and drove his right-foot shot past Marc Robinson.
