Stephen Carson congratulates goalscorer Davy Patton

Davy Patton controlled a John Neill through ball and fired a left-foot shot past Dwayne Nelson to score Coleraine's winning goal after two minutes.

Paddy McLaughlin then had an effort cleared by defender JP Gallagher.

The Swifts piled on the pressure, with Aaron Baker having a shot deflected wide and Timmy Adamson going close.

Jamie Tomelty skewed a shot wide, Gallagher was off-target and Mark McAllister had a shot blocked while Nelson saved from Matthew Crossan.
