DESPITE dominating much of the second half of a disappointing match at MacHale Park, Sligo were unable to breakdown a resolute Mayo team who had done the damage in the first half.
Trailing by five points at the interval, the Yeats County hit the ground running in the second half with two points in as many minutes.
However, the point of the match came from Mayo's star man Michael Plunkett, who restored a four-point lead, but in truth Sligo should have closed the gap further but for some wastefulness up front.
Mayo were not in the least bit flattered by their interval lead of five points and only for some excellent goalkeeping by Sligo's Kevin Kelly, they could have bagged three goals.
The one they did score came via the penalty spot from Adam Gallagher on 24 minutes.
But once Sligo took control of midfield in the second half, Mayo were on the back foot but an excellent half-back line of Plunkett, Pat Durcan and Cian Burke played no small part in securing a place in the Connacht final for the home side.
