Limerick 37 defender Shane Tracey held his nerve to fire home two dramatic late penalties to secure his sides first win of the season at Jackman Park.
Tracey netted his first from twelve yards in the 87th minute after a Youths defender handled the ball on the line, and then converted another following an Anthony Rossiter handball two minutes later.
To compound the misery for the visitors, ex Lims favourite Conor Sinnott saw his injury time spot kick saved by keeper Dave Ryan after the hosts were penalised for handball.
The Youths almost drew first blood, James Hayes flashing a low shot across the face of the goal, and the same player then drove a volley inches over from Sinnotts resulting corner.
Lims responded via ex-Arsenal youth ace Tracey, whose cross landed on the roof of the net, much to the relief of visiting keeper JasonRussell.
The visitors posed a threat late in the first half after a flying Paul Malone header from another Sinnott cross drifted just outside Dave Ryan's right post.
Lims, who played most of the football in the first half, almost edged ahead in the 43rd minute when Tracey's free kick shaved the outside of Russell's left upright.
And the hosts had the visitors on the back foot again in injury time, forcing two corners in a row after some nervy defending from the Youths.
Padraig Fogarty and the hard working Wayne Colbert went close for the Shannonsiders after the break but were denied by some fine saves from Russell.
