Galway made it two out of two in Division 1 when seeing off Dublin 1-17 to 0-6 at Duggan Park, Ballinasloe.
The visitors were coming off a fantastic victory over Tipperary but never got going against the westerners, who were outstanding, particularly in the opening half.
Whereas Dublin only managed one point in that first period, courtesy of free-taker Muireann O'Gorman, Galway registered 13.
Jessica Gill, Veronica Curtin, Aislinn Connolly, Tara Rutledge, Brenda Hanney and Noreen Coen put their names on the scoresheet and Dublin had no answer.
The Sky Blues were much more competitive after the resumption, but with Sarah Dervan a commanding force at centre-back for Galway, they remained heavily reliant on O'Gorman's accuracy from placed balls and she added four more points from frees. Ciara Berkeley registered their only point from play 10 minutes from time.
With two minutes to go, Connolly found Curtin in space and she drilled a powerful shot to the net to complete the scoring and put Galway in a strong position to grab a semi-final spot.
Meanwhile, Waterford stayed on the rise with a brilliant 0-10 to 0-7 victory over neighbours Wexford in Division 2.
Jackie Quigley and Susie McGovern were among the scorers for Wexford, but Waterford always had their noses in front, due largely to Deirdre Fahy's five points.
With Zoe O'Donohue and Nicola Morrissey also finding the mark, that was enough for the Suirsiders to celebrate a memorable win.
