Gary Shaw’s first two goals of the season sealed all three points for Shamrock Rovers who took a deserved win at Eamonn Deacy Park.
Shaw fired the Hoops ahead early on, then stepped up with a winner midway through the second half after Ronan Murray drew Galway United level 13 minutes after the break.
In front of 1,051 supporters in Galway, Shaw ran on to Ronan Finn’s through ball and hit the net for the first time this season in the second minute.
After that early blow, United suffered another setback with the loss of striker Padraic Cunningham through injury after 15 minutes, and they never looked like finding the equaliser before the break.
Rovers were good value for their 1-0 half-time lead, but after some good work from David Cawley, Murray hit the leveller with the aid of a slight deflection.
But when Conor Winn couldn’t punch clear, Shaw gratefully cleaned up for a vital three points.
Galway United – Winn; C Horgan, Grace, Folan, Ludden; Shanahan (Melody 78), Byrne (Deevers 89), Holohan, Cawley, Murray; Cunningham (Faherty 17).
Shamrock Rovers – Chencinski; Madden, Devine, Webster, Clarke; Meenan (Corry 69), Finn, Lopes, Connolly, Miele; Shaw (Boyd 75).
Referee: R Hennessy (Clare).
