Sean McCaffrey’s side will be kicking themselves for not putting the visitors to the sword, though, in a first half they dominated. The Lilywhites got a dream start when Michael Rafter fired them in front after just 22 seconds.
However, despite a series of chances, they failed to add a second and Monaghan equalised with their first shot of note, three minutes into the second half as Keegan hit a thunderbolt from 25 yards. The ex-Southampton trainee then clinched victory bursting through on 63 minutes before steering a low shot past a helpless Peter Cherrie.
