DUBLIN got back to winning ways at the expense of Mayo who flopped before a crowd of 13,548 at MacHale Park, Castlebar.
The home side had no answer to the blistering pace and power Dublin displayed as they revelled in the room that Dublin created for themselves, particularly in the first half.
Jim Gavin's team made two changes to their published line up - Diarmuid Connolly returned to county duty after his club campaign with St Vincent's in place of Emmet O'Conghaile, and Paul Flynn made his first start, replacing Paddy Andrews.
Mayo started as selected, and did not include ace scorer Cillian O'Connor in the subs. O'Connor was reported to be suffering from a hamstring problem.
Mayo opened the scoring with a point by Jason Doherty after just 25 seconds - and then the roof caved in on them as Dublin stormed through the first half in irresistible mode.
They scored 2-10 in the opening half while the home side were helpless to stop the Blue marauders, with Kevin McManamon showing his blistering pace to great effect.
The first goal came after seven minutes. Paul Flynn played in Bernard Brogan whose goal-bound shot came off the crossbar and Denis Bastick slotted the ball to the net.
Goal number two had a question mark as from the stands, it appeared that McManamon bounced the ball twice during a searing run that gave Bernard Brogan a chance to palm the ball home in the 22nd minute. However, referee Padraig O'Sullivan saw nothing wrong and allowed the goal.
The Dubs came out for the second half leading by 2-10 to 0-6 and Mayo were left with a huge task to save face, never mind the League points at stake when play resumed after the interval.
It did not start well, with early wides by Mark Ronaldson and Keith Higgins, and Dublin tacked on points by Jack McCaffrey and Paul Flynn to extend their total to 2-12 after 43 minutes.
Only a fine save by Mayo keeper Rob Hennelly prevented McCaffrey's shot from going into the net.
Denis Bastick made a superb goal line save to stop a Ronaldson shot giving Mayo a goal in the 44th minute, and a Rock free extended the Dubs lead to 13 points, before scores by Doherty from a free and sub Danny Kirby got Mayo off the mark in that second half.
The game became a tighter and at times niggly affair, but the Dubs stayed in command. The only blemish was a late black card for Dean Rock who could leave the field with his head held high, having scored six points, all from frees.
