At the break calming words asking Pats to show a little more composure and patience saw them start the half better and begin to pass the ball well.
But as the half wore on it looked like a result would be hard to find as Cabinteely defended resolutely. Will McMahon forced the Cabinteely keeper into two fine saves but still no break-through.
Eventually it did come and it took something special.
In the 53rd minute Keifer Byrne's brilliant bursting run from midfield had the Cabinteely defence scrambling, a one-two with Karl Tims, saw Byrne break the last line of defence to shoot low into the corner, one-all.
Now back on level terms and with the news from Carragh Road that it was still scoreless between Naas and Templeogue it meant that if both games remained the same it would be enough, however Pats continue to press for a winner.
With just 8 minutes remaining another bursting run by Keifer Byrne was halted on the edge of the box. Karl Tims fired in the resulting free kick and saw it loop into the top left corner. Mobbed by his team-mates it gave Pats that precious lead.
Cabinteely chased the game for the last few minutes but could find no way through, so when the final whistle sounded Pats had secured the 3 points needed for 2nd spot.
The result from Naas was immaterial but even that went Pat's way as it ended 0-0 in Kildare.
The 14's now go into a play-off against the 2nd from bottom team in the Premier Division for promotion.
