St Sylvester’s forward Niamh McEvoy ended the contest with an impressive personal haul of 1-5 and was instrumental in steering the Metropolitans towards a second consecutive top-flight triumph.

Trailing by six points (3-2 to 1-2) after 20 minutes, Mick Bohan’s charges slowly reeled in their Connacht rivals.

After the westerners stormed in front with unanswered points from the Kelly sisters – Niamh and Grace – full-forward Rachel Kearns rattled Ciara Trant’s net with a powerful strike.

Dublin’s initial response to this set-back was immediate – Niamh McEvoy’s unstoppable effort raised a green flag at the opposite end – but they suffered a further blow on 11 minutes. Despite hitting the post off a close-range free, Kearns bagged her second goal off the ensuing rebound.

The holders narrowed the gap with a second Davey point, only for Fiona Doherty to subsequently fire home from a tight-angle for Mayo’s third major of the half.

The early introductions of Siobhan Killeen and Jennifer Dunne – Player of the Year Sinead Aherne followed in the second half – added an extra spark to the Dublin play, and they helped to reduce their deficit to 3-4 to 1-6 at the interval.

Nicole Owens and McEvoy split the posts on the resumption to bring the gap down to two, but they breathed a sigh of relief when Kearns' 38th-minute penalty blazed over the crossbar.

Although full-back Niamh Collins was sin-binned as a result of the latter incident, Dublin out-scored their opponents 0-4 to 0-1 in her absence. McEvoy (two), Carla Rowe and Killeen found the range in this period, while Clodagh McManamon mustered a solitary Mayo score.

The returning Aherne and McEvoy edged Dublin in front for the first time with consecutive frees, before Doherty’s two-point salvo levelled matters moving into the home stretch.

Dublin never panicked though, and McEvoy and Davey raised white flags in the dying moments to see off the Mayo challenge.
