Ballinamallard 0 St Pat's Athlone 1: Ballinamallard United must attempt to turn around a one-goal deficit in the second leg of their Setanta Sports Cup quarter-final against St Patrick's Athletic.
Craig Forrester's 21st minute close range finish settled the first leg at Ferney Park, but the Mallards will still believe that they have a chance of causing an upset.
St. Pat's made the breakthrough when former Republic of Ireland international Keith Fahey rolled the ball across the box for Forrester to tap in.
And the visitors, who dominated throughout the first period, went close to doubling their advantage 10 minutes later when Forrester rose to meet a Conan Byrne corner but he could not steer his header on target.
St. Pat's continued to press early in the second half with Killian Brennan having a free kick punched away by McCusker.
It was a much improved second half though from the home side and it needed St. Pat's defender Kenny Browne to be alert as he cleared away a through ball with Davy Kee ready to pounce.
Ballinamallard then forced St. Pat's goalkeeper Rene Gilmartin into a fine save to deny Kee, who got his head to a Cathal Beacom free kick with 20 minutes to go.
The Mallards had a chance to snatch a draw through Andy Crawford in the 86th minute but he could not beat Gilmartin.
