Hughes provides cushion for Shels
The opening goal came in the 18th minute after Cassidy broke from an Athlone corner and fed Chris Mulhall on the right. His cross seemed to have too much on it but Conan Byrne controlled the ball superbly and set up Kevin Dawson for a tap-in.
On 66 minutes Shels pulled further ahead as the Athlone defence stood still, allowing Mulhall to steal the ball. Michael Schlingermann dived in, Mulhall tumbled and referee Darren Coombes pointed to the spot.
