Mayo’s misery will extend to a 66th year after Dublin’s excellent bench scored them a second successive All-Ireland title this evening, their hero in the drawn final Cillian O’Connor widing a last gasp free to force extra-time.

In front of 82,249, Dublin’s depth of reserves were to the fore in guiding them to glory in this replay, substitute Cormac Costello scoring three points, Bernard Brogan one and Michael Darragh Macauley was a human wrecking ball in setting up scores.

This replay threatened to go out of control in the first half but calmed down after the break when Dublin never looked backed after Diarmuid Connolly’s 42nd penalty goal, coming courtesy of Rob Hennelly fouling Paddy Andrews after misjudging a Paul Flynn kick. Hennelly was black carded and replaced by David Clarke

It put them three ahead, a lead they never lost although it was reduced to one on three occasions by Mayo. Brogan cancelled out a Kevin McLoughlin point and Patrick Durcan’s second point was followed by a Costello brace.

Two Cillian O’Connor frees made it a one-point game and then Brian Fenton, already on a yellow card, was fortunate to stay on after a cynical foul. Costello sent over his third in the first minute of additional time only for O’Connor to convert a free for a foul on Barry Moran. A foul by Costello by Durcan gave O’Connor that 11th hour chance but it tailed wide of the near post.

Referee Maurice Deegan was the talk of the first half having neglected to black or red card John Small for obvious incidents. Instead, the referee chose to dismiss Jonny Cooper and Lee Keegan for cynical if not black card offences.

Small should have walked for a trip of Andy Moran in the eighth minute but only the foul was acknowledged, while he appeared to make an attempt to strike Cillian O’Connor off the ball in the fifth minute of first half additional time. Connolly could also have been collared for a third man tackle on Donie Vaughan in the same movement.

There was football played too and Dublin jumped into a 0-4 to 0-0 lead after seven minutes as they feasted on Mayo indiscipline and some pretty awful kick-outs. Hennelly had come in as a late replacement for Clarke but he wasn’t enjoying much success.

Mayo fired back with four of their own points before Dean Rock kicked over a brace of frees, two of six from him in the first half.

But then Mayo goaled, Aidan O’Shea moving superbly behind Philly McMahon to slide in front of Cian O’Sullivan. He made some progress before offloading to the on-running Keegan who finished to the net.

Dublin were quickly back on level terms through a Rock free and then went ahead with another as Mayo’s foul count shot up. A Cillian O’Connor arrested that run but then Connolly fired over beautifully and from the resultant kick-out drew the black card free from Keegan and Rock did the rest.

O’Connor finished the half’s scoring with his fourth free and the half came to an unseemly finish with a row originating from the Connolly-Vaughan and Small-O’Connor flashpoints.
