Tommy Dunne’s team produced a defiant display in the west to secure their most impressive result since returning to the top flight 17 months ago.
Plagued by inconsistency since the start of the seasonthis match confirmed Galway’s ability when the mood strikes.
Though Dundalk dominated vast chunks of the game Galway contributed to a lively encounter demonstrating an admirable willingness to graft throughout.
When a chance was presented on the stroke of half-time Faherty pounced for his 11th goal of a productive campaign.
When the action recommenced in the second half Dundalk just couldn’t find a way past a Galway defence that was marshalled in superb fashion by Stephen Folan.
Dundalk pressed forward in search of a leveller, but Galway held on to eke out the full complement of spoils in front of 2,578 spectators.
Buoyed up by their stirring European Champions League qualifiers run Dundalk started brightly putting Galway under duress. Galway goalkeeper Conor Winn had to be alert early on as Galway survived a couple of real scares with Dundalk keen to exploit their superior physical strength.
A fifth minute Darren Meenan free-kick forced a fine reflex save from Winn and Dundalk came close again following the resultant corner.
Meenan’s delivery caused panic in the Galway area with Ciaran Kilduff making a firm headed connection, but again Winn was able to thwart the visitors’.
Initially the Tribesmen were struggling to pass the ball with any real fluency such was Dundalk’s industry, especially in the centre of the park where Robbie Benson was prominent.
In the 33rd minute a Daryl Horgan free-kick was gathered by Winn with the Lilywhites keen to land a blow. But as the first-half lingered on Galway improved considerably with skipper Ryan Connolly’s influence increasing.
Three minutes before the break Folan hooked the ball over the bar following a Connolly free-kick, but Galway still managed to land a blow.
Stephen Walsh’s splendid 45th minute cross located Vinny Faherty, who supplied a similarly sweet header and suddenly Galway had a lead to protect.
After the restart Dundalk boss Stephen Kenny introduced prolific striker David McMillan to partner Kilduff. Chris Shields flashed an effort over the bar in the 61st minute, while a crisp Benson attempt drifted narrowly wide. There was no shortage of attacking talent on the pitch for Dundalk, but Galway were brave with Paul Sinnott and Connolly busy in the centre of the park.
In the last minute substitute John Mountney’s corner was headed over by Kilduff and a resilient Galway held on to record a fine win.
